Doepfer NAMM 2018 A-100 Polyphonic Module Announcements

Right in time for the upcoming NAMM exhibition later this week (January 25/28 2018, Anaheim, Hall A, booth 10706), Doepfer announced a few more interesting A-100 modules (next to the Dark Energy III news). Too many new modules for one blogpost, so I had to split it up into multiple blogposts... The next one will contain their new 'standard' modules.

The magic word for Doepfer this year seems to be Polyphony, because most of the new products are perfect companions for the highly anticipated A-190-5 Polyphonic CV/Gate Interface, a module that has been in pre-production for a loooong while now. 

On the Doepfer website we can still read the message We cannot yet specify a definite release date but hope that it will be available in 2011, from the early prototype stages.

We already know most of its features, i have been blogging about it since 2011, but here are the details once more:

A-190-5 is a Midi/USB interface that generates 4 gate signals and 12 control voltages to control up to four synthesizer voices (i.e. VCOs and associated modules like envelope generators, VCFs and VCAs) for polyphonic sound generation. 

The A-190-5 will be equipped with different polyphonic, duophonic, paraphonic and monophonic modes which are selected by means of menu buttons and the display.
For each channel a gate, a note controlled CV (1V/Oct.) and two auxiliary CVs (e.g. for velocity or controlled by midi control change messages) are available. In play mode the states of the four gates are displayed by four LEDs integrated into the buttons 1-4.
Firmware updates are possible via USB.

The A-111-4 Quad Precision VCO will be available soon too... adding 4 wide-range precision-VCOs to complement the Polyphonic module and was already announced at Superbooth 2017. Read all about this at http://patchpierre.blogspot.nl/2017/04/superbooth-2017-new-doepfer-module.html

A-105-4

Brandnew is the A-105-4 Quad SSM VCF filtermodule, their first polyphonic filter and contains four identical 24dB Lowpass filters (SSM2044 type).
The special feature of the 4 pole low pass SSM2044 is the patented so-called "true open loop design that delivers a characteristic fat sound not available from other devices"

This chip was used e.g. in these synths: Korg Polysix, Korg Mono/Poly, Fairlight II, PPG Wave 2.2 und 2.3, Emu SP-1200, Siel KIWI,  DK600, Siel Opera 6, and the Simmons SDS5.

The first Prophets 5s used the SSM2040 - the precedessor of the 2044 - that generates a very similar sound. (source)  Version 3 of the Prophet 5 switched to the thinner sounding Curtis CEM3320. The Pro One also used that chip.

It has available common manual controls and CV inputs with attenuators for these parameters:
• Frequency (F)
• Frequency Modulation Intensity (FM)
• Resonance (Q)
• Audio Input Level (L)

Each filter has available a separate FM input as well as an Audio Input and Output. The FM input is typically connected to the output of the associated envelope
generator (e.g. A-141-4). The envelope amount for all four filters is controlled by the FM knob and the CVFM input by means of four built-in VCAs, which are controlled by the FM control and CVFM input.

A-132-8

This allows also voltage control of the envelope amounts. In addition common frequency modulation for all filters is possible (e.g. by an LFO). For this the CVF input with attenuator can be used.
The range of the audio input level control (L) allows also clipping/distortion with typical A-100 audio levels (e.g. from A-111-4) at the filter inputs.
Even this parameter is voltage controllable as well as the resonance (Q).
Application: polyphonic patches (four VCFs with same parameters)

Another new Polyphonic module is the A-132-8 Octal VCA:
The A-132-8 contains four VCA pairs. Each pair includes two daisy-chained VCAs. One VCA has a linear control scale, for the second VCA linear or exponential control scale can be chosen by means of jumpers.
Doepfer decided to provide two VCAs for each voice because usually one VCA is required for loudness envelope and a second one for velocity (or another function).
For each VCA these in/outputs are available:

A-141-4

• CV Input VCA 1
• CV Input VCA 2
• Audio Input
• Audio Output
Audio Sum Output is also available.
The module features two Initial Gain controls, that enable the opening of the first (G1) and/or second VCA (G2). This is necessary when the VCA in question is not in use (i.e. no external CV available). Otherwise the VCA would close. They are also useful for testing polyphonic patches.
Application: Polyphonic patches with two VCAs per voice.

The A-141-4 Quad Poly VCADSR contains four ADSR type voltage controlled envelope generators with common manual controls and CV inputs with polarizers for the parameters Attack (A), Decay (D), Sustain (S) and Release (R).

Each of the four envelope generators has available a gate input, a control LED and an envelope output.
Application: Polyphonic patches (four envelope generators with the same envelope parameters to control four VCFs, VCAs or other modules)

More A-190-4 MIDI-CV/Gate/Sync Interface Specifications

Last year, quickly after the A-190-4 prototype suddenly appeared in the wild, i already contacted Dieter Doepfer about some of the specs of the module.

The Doepfer A-190-4 will be the new replacement for module A-190-1 which is no longer available.

The functions of A-190-1 and A-190-4 are nearly the same (Midi In, Midi Out, CV1, CV2, Gate, Clock, Reset), but the operation of the A-190-4 has been improved because a 3-digit LED display is available.

The current values of all parameters (like Midi channel, reference note, clock divider) can be read back and modified by means of up/down buttons.

In addition A-190-4 is equipped with an USB interface and the external +5V supply is no longer available.

A-190(-1)  MIDI-CV/Sync
Interface

The A-190-1 has 2  DACs (Digital-to-Analog Converters)

In the original A-190-1 DAC 1 is 'hard-wired' to receive MIDI note messages and convert them into control voltages available at CV output socket CV 1. This DAC has 12-bit resolution, which gives excellent tuning resolution (in steps of 1/4096th). As a rule, DAC 1 will be used to control VCO pitch.
DAC 2 can be assigned to your choice of MIDI controller. This DAC has 7-bit resolution (1/128th steps).

At the time (almost one year ago) Dieter couldn't tell much about the processing power and if any other functions would be available (arpeggiator? like the A-190-3), but this week I have managed to get a bit more info.
Christian Assall, software developer at Doepfer, was kind enough to explain a few more things about the A-190-4 via e-mail:

A-190-4 Prototype

- "The A-190-4 will have 2 new DACs... Because the development of the A-190-1 was now before more than 15 years, it makes sense to use modern pieces."

- "DAC2 will now also be 12 bit and will have a range of 0 ... 10 + volt ( but can also only use it for velocity/controller and things similar to the A190-1 , but not for pitch/tune controlling like the CV1 - so it's not possible to control two voices - because you also have only one gate ;-) - for polyphonic things we have the A190-5 in development"

About future firmware updates:
- "As the next development in schedule list is the A-190-5 - which is something like a 'great' brother of the A-190-4 - the A-190-4 has in most cases the possibility to inherit his features...

...so it's more a question of what we and the users want and decide to include in a preferably easy to use CV-interface the A-190-4 should be... This also belongs to the topic arpeggiator."

The A-190-1 Arpeg. mode never got released 

About the somewhat hidden arpeggiator-function in the A-190-3:
- " It's more a cost-free present or an eastern-egg like thing than a real feature in my eyes, because it hasn't any dedicated switches or display for that - so I think it's for many users hard to use ...
But if you can - sure you can use it and you can do some arp. things without any additional devices/software ...."

- " We never released this feature in the A-190-1, mostly because of the not optimal user interface, that was not suited in our eyes for additional and such a complex features.
An arp. should have a dedicated/suitable user interface - otherwise it didn't make much sense in my experience/eyes.
Sure also the weak processor power was a reason, not to try with many tricks to get an arp. which is in timing and didn't interfere with the other functions of the module.
So, never to release, was more a matured consideration that came from practical experiences..."

The A-190-1 will be replaced by the A-190-4 from about April 2014.

As of April, the Doepfer BS basic systems will come with an A-190-4 installed...

DIY Eurorack MIDI-to-CV Converter by Stereoping

Today i discovered Stereoping and its interesting line of products.

Stereoping was founded by Gregor Zoll.
Since his graduate to a graphics designer he is selfemployed in 3D-computeranimation, programming and development of computergames.
As a sideline he always made lots of music and repaired, altered and – in the end – developed lots of musical equipment like drumcomputers and synthesizers.

Stereoping MIDI-to-CV
Converter

As his ideas got more concrete and his developments got more professional through the years, he started a business in 2013 for the development and worldwide shipping of innovative diy-assembly kits for musical devices.

If this business will develop as he hopes, his goal will be to offer complete out-of-the-box products in some years...

Stereoping produces 'DIY assembly kits for making magical music' and will be opening a webshop in early 2014, where he will be selling some of the products shown on their site.

Some modules will also be available as a DIY-kit...

They also have a special Eurorack section on their site with interesting stuff.

The latest product is this Eurorack MIDI CV Interface, a basic MIDI-to-CV converter which is really not that innovative, but still a good piece of work IMO.

I like the plain and simple design of the panels, and I'm looking forward to seeing more modules coming from this new company.

Video: Demo for my DIY Eurorack Module 'Midi CV Interface'

" Short and musically quite boring demo of the features of my Eurorack diy Midi-CV-Interface. In case you dont know: such an interface lets you integrate the analogue module system into the digital midi production set. It has - besides Pitch-CV and Gate - simultaeneous outputs for velocity and 2 controllers. It can learn the midichannel (and remember it) and be set to single trigger (held notes will not send another gate) or multiple trigger. It also has a potentiometer to set the glidetime (portamento). A switch lets select if all notes should be glided or just held notes.The latter gives kind of temporary glide like on the tb303. It also has 5 Volt outputs for midiclock and sequencer-start/stop (both not features in this video). More technical info on my homepage. Sorry for the bad video quality, forgot to disable manual focus."

Doepfer A-190-8 Midi/USB to Sync Interface Now Available

At the end of the year, Doepfer finally announced that the A-190-8 Midi/USB to Sync Interface is available starting today.

A-190-8 Prototype

Basically this module divides the incoming MIDI or USB clock messages into smaller steps.
You could look at the A-190-8 as a modular version of the MSY2 MIDI-to-SYNC Converter.

It was already announced in December last year, and besides the normal MSY2 functions this module also features multiple simultaneous outputs and added USB support.

Here are the most important features of this version of the module:

- Midi input (recognizes only Midi realtime messages clock, start, stop and continue)

- USB input for Midi via USB

-Clock outputs:
96: outputs the Midi clock 1:1 (96 pulses per measure/ppm or 24 pulses per quarter note/ppq)
32: outputs the Midi clock divided by 3 (32 pulses per measure/ppm or 8 pulses per quarter note/ppq)
16: outputs the Midi clock divided by 6 (16 pulses per measure/ppm or 4 pulses per quarter note/ppq)
8: outputs the Midi clock divided by 12 (8 pulses per measure/ppm or 2 pulses per quarter note/ppq)
1: outputs a pulse at the start of each measure

- Other outputs:
Start: outputs a pulse at each Midi Start or Continue message or generates a gate signal that remains in the high state until a Midi Stop message occurs (selectable via jumper)
Stop: outputs a pulse at each Midi Stop message
Reset: outputs a pulse at each Midi Start message that follows a Midi Stop message

- Wait control input, can be selected by means of a jumper between Gate function or Switch function: in - Gate mode the positive edge of a gate signal is used to init the Wait state, in Switch mode an external switch that connects to GND is used to init the Wait state (equivalent to Switch-Trigger)

- Wait button / Wait control input: Whenever the Wait button is operated or a positive voltage is applied to the Wait input the module waits for the next measure start until the clock signals are generated.

- LED displays for clock, "1" and start (display of Start depends upon the chosen Start mode, see above)
output voltages can be selected between +5V and +12V by means of an internal jumper (for DIN Sync applications +5V has to be used !)
firmware updates via USB (provided that there will be updates available)

Doepfer History: MCV8 8-Voice MIDI to CV Interface

In the mid 80s Doepfer released the MCV8, an 8-Voice MIDI to CV Interface.
The MCV8 was/is a simple MIDI-to-CV converter, featuring MIDI in/THRU plus 8 CV and 8 Gate outputs on the backside.
On the front side it had a two-digit LED plus 8 buttons.

MCV8 V2 frontside

A preliminary version of the MCV8 (very different from the final version) was available around 1985/86.
It was very primitive and had only one mode: 8-voice polyphonic.

The only controls were a learn button and a LED (to learn the Midi channel and the reference note for 0V CV). The unit had no storage and the Midi channel and reference note was lost after power off.

Only very few units were manufactured (as far as Dieter remembers less than 10). 

MCV8 V2 backside

A few years later a totally revised version of the MCV8 was available (both kit and ready made). 

The kit was about Euro 150 without case and about Euro 180 with case. 

The ready built unit with case was about Euro 280. It had a 2-digit LED display and 8 buttons with associated LEDs and was available without or with case (a ugly black plastic box, not yet 19"). 

The CV and gate outputs were available as a sub-d socket (no jack sockets) and one had to solder a special cable that converted the sub-d e.g. to 1/4" jack plugs. 

It had already different modes (8 voice polyphonic, 2 x 4 voice, 4 x 2 voice, additional controller outputs and so on) but it had no memories.

Around 1990 version 3 of the MCV8 was released.

It was available as a 19" unit with 16 1/4" jack sockets at the rear panel for 8xCV and 8xGate.

The unit had a non-volatile memory for several user presets.

Doepfer MCV8 19-inch rack with Version 3.1 Manual

The buttons could be used to setup different parameters like Legato On/Off, Gate Polarity, Pitch Bend On/Off (only in V/Oct. mode), Type of CV Characteristic (V/Oct. or Hz/V), MIDI Note Reference for 0V CV in V/Oct. mode and Pitch Bend Travel of CV (only in V/Oct. mode)

The MCV8 Version 3 Offered 6 standard modes/configurations:

Poly 8 (P8): 8-Voice polyphonic
All 8 CV outputs are pitch outputs (controlled by MIDI note on/off) on the same MIDI channel
Poly 4 (P4): 4-Voice polyphonic
The CV outputs 1-4 are pitch outputs (controlled by MIDI note on/off) on the same MIDI channel.
The CV outputs 5-8 are the corresponding velocity outputs (controlled by the velocity values of the note on/off events)
Poly 2 (P2): 2-Voice polyphonic
The CV outputs 1 and 2 are pitch outputs on the same MIDI channel, 3 and 4 are the corresponding velocity outputs, CV5 is the (monophonic) after touch output and CV 6...8 are controller outputs.
Single 8 (S8): 8-Voice monophonic
Each CV output is a pitch output on a different MIDI channel.
Single 4 (S4): 4-Voice monophonic
The CV outputs 1-4 are pitch outputs on 4 different MIDI channels.

The CV outputs 5-8 are the corresponding velocity outputs.
Single 2 (S2): 2-Voice monophonic
The CV outputs 1 and 2 are pitch outputs on two different MIDI channels.
CV 3 and 4 are the corresponding velocity,
5 and 6 the after touch, 7 and 8 controller outputs.

Besides the User Presets it had a memory for 6 user definable presets, what made this a very versatile MIDI-CV converter for its time
The CV-range could be configured to do the usual 1V/Oct (standard) or the Korg/Yamaha type Hz/V,
and the Gate output could be configured to do +5V / +7.5V and/or the Moog type S-Trigger by switching internal jumpers.

The price for the ready built unit was about 380 Euros, the kit was about 275 Euros.
There were some differences in the Version3 firmware features but details are unclear.

Doepfer MCV8 Version 3 Backside

Doepfer still has a text file of the manual on their website, you can find it HERE but a nicer  PDF of the manual can be found via the Cykong site.

It is difficult to say how many were sold as Doepfer only have records from since 1990. 

From 1990-1995 about 300 were sold, but they have no quantities before 1990. 

Dieter expects around 400-500 units were sold altogether.

Doepfer A-190-5 Polyphonic USB/MIDI-to-CV/Gate Interface Preliminary Info

Planned to be released in the fall of 2013*,  so more and more details keep popping up on the internet about the A-190-5 four voice Polyphonic Midi to CV/Gate interface.

The prototype of this module already been displayed at MusikMesse 2013 and at Dieter´s latest workshop in Munich, Germany last month.

The first design of the
A-190-5 (then A-190-3)

To keep the price low, the first design of the A-190-5 was based on Doepfer's  MTV16 Midi-to-Voltage Interface with 16 Analog Voltage Outputs ( an OEM/DIY product that is still available)
The 16 outputs of the MTV16 were buffered and connected to 16 jack sockets.
Additional controls (momentary button, LED, rotary switch) had been added compared to the MTV16.

Early last year Doepfer gave up the idea to built the A-190-5 on base of the MTV16.

The new A-190-5 is now a completely redesigned version that contains an LC display (similar to the A-187-1), some control buttons, a USB interface and higher resolution DACs with higher voltage range (probably 12 bit and 0...+10V).
It will have 12 CV and 4 Gate outputs, different modes (e.g. unisono, four-fold monophonic or polyphonic, and different four voice polyphonic modes)

For each voice a pitch control voltage (CV1, 1V/octave standard to control VCOs), a gate output (to control envelope generators) and two additional control voltages (CV2, CV3) are available. The two additional CV outputs can be controlled by Midi velocity, volume, modulation, pitch bend, after touch or free assignable Midi controllers.

Doepfer A-190-5 Final Prototype

The basic modes can selected by means of a momentary switch (probably Mode or Algor.) and is shown in the LC display.
Certain parameters of each mode can be edited (e.g. the midi channel(s), the midi reference note for 0V CV, assigned controllers for CV2 and CV3).
For this the momentary switch Edit/Play is used.
The parameter values (e.g. midi channels) are shown in the display and can be modified by means of the momentary switches 1...4.
In Play mode the LEDs of these four switches display the gate states.

The range of the CV outputs (CV1...CV3) is 0...+10V (i.e. 10 octaves for CV1). The resolution is 12 bit.
The gate voltages are 0/+5V (maybe even adjustable to 0...+10V for non A-100 applications).

The first version of the module will be available around fall 2013 at the price of approximately Euro 300.00* and will include the most important assign algorithms.
Updates and bug fixes can be installed by the customer via the USB interface.

Update September 1:
Dieter Doepfer: " The A-190-5 is still under development. The hardware (pc boards, frontpanel) is ready made but the firmware is not yet ready. But I hope we will release the A-190-5 still this year."

More A-190-4 News

I contacted Dieter Doepfer about the A-190-4 USB/MIDI-to-CV/Gate/ Sync Interface that showed up at a modular synthesizer workshop in Munich earlier this month...
They showed a prototype of a module that wasn't announced yet, and i was glad Dieter had a bit more information.

A-190-4 prototype

He replied to me that the A-190-4 will replace the A-190-1 as the A-190-1 has been developed more than 15 years ago and is a bit old-fashioned and long-winded to operate.

Mainly the missing display has been complained by several customers (i.e. no display of the parameter like midi channel, reference note, scale settings, portamento and pitch-bend range, clock divider, status of the built-in (software) LFO and so on). 

The basic functions of the A-190-4 will be the same as the A-190-1 but the man-machine interface will be better because of the display that shows the parameter value. It will also be equipped with USB. 

The module is still in the prototype state and they expect that it will be available end of 2013 or early in 2014. 

Pricing was not yet available.

At this time Doepfer could not promise that an arpeggiator will be included. 

The programmer of the A-190-4 (Christian Assall) has to decide if this feature will be available (maybe in a future firmware version as the module can be updated via USB)

I guess it does have a little bit more processing power than the original A-190-1, because the 'promised' arpeggiator function on that module never got released.
Last year Dieter already explained to me that there were plans to add an arpeggiator when the A-190-1 was designed about 15 years ago. 

But they found out later that the processor power was not sufficient to add this feature...

Doepfer A-190-4 USB/Midi to CV/ Sync Interface Prototype Revealed at Workshop

A few weeks ago, on July 13, Dieter Doepfer personally appeared at a modular synthesizer workshop in a shop in Munich, Germany, together with a huge Monster Base rack filled with Doepfer modules and an LCB angled basic case with some of the newer modules like the earlier announced A-157 Trigger Sequencer subsystem and the A-190-5 Polyphonic MIDI-to-CV/Gate Interface.

The two-part workshop was very well attended: 50 synth freaks (newcomers and advanced users) followed Dieter Doepfer’s explanations and presentations with enthusiasm.
Although i wasn't there, it can see what an amazing event this must have been; the A-100 modular system explained by its inventor...

A-190-4 prototype

Find the full report and many great pictures at http://greatsynthesizers.com/en/general-en/2013/07/dieter-doepfer-introduces-new-a-100-modules/

Besides all the new A-100 modules there was also a prototype of an A-190-4 USB/Midi to CV/ Sync Interface, that hasn't even been announced yet...
It looks a bit like any other basic Doepfer MIDI-CV converter (like the A-190-1 and A-190-3), but this one has a basic seven segment LED display for showing parameter settings.
I hope that this one does have a (basic arpeggiator function though...

I hope to get more info soon...

Doepfer History: Doepfer MCV1 MIDI-to-CV Converter

In 1986 Doepfer introduced the first in a series of MIDI-to-CV interfaces, the MCV1.
The MCV1 was a monophonic MIDI-to-CV/GATE-Interface that could control other vintage analog synthesizers equipped with CV and Gate/Trigger inputs via MIDI.

MCV1 front (version 4 or 5)

MCV1 was equipped with MIDI in and Thru, one CV (control voltage) output to control the VCO's (Voltage Controlled Oscillator) and a Gate/Trigger output to control the Envelope Generators.
It was suitable for synthesizers using standardized V/Octave or Hz/V and gate voltages from +5V to +12V or switched trigger (S-Trig)

The factory setting and adjustment of the CV output was 1.00V/Octave. To change or re-adjust the scale you had to insert a small screw driver into the the hole labeled ADJUST/ or SCALE right of the CV jack and turn the potentiometer setting to the desired value.
The factory setting for the GATE output was +5V voltage gate, and if you wanted to change the setting you had to remove the cover plate.
On the PC board inside you could find a  jumper that could be set in 3 ways: +5V or +U voltage gate or SWITCH TRIGGER (S-TRIG. e.g. used by MOOG).

There was also the possibility of changing additional settings by Program Change control numbers.

The interface had no separate ON/OFF switch nor have a built-in power supply. Instead it used an external plug-in type.

Back side of the MCV1 plus external adapter

The pictures probably show version 4 or 5. 

Versions 1 and 2 were available only as kits and there was no suitable housing available (i.e. pcb only). 

Version 1 had no sockets on board. The MIDI and CV/Gate sockets had to be wired manually. 

Version 2 had MIDI and CV/Gate sockets on board. MIDI channel and other parameters were adjusted by means of a DIP switch. 

Version 3 was a redesign of version 2 so that a small standard case could be used (the case in the picture). 

As far as Dieter remembers the only difference between versions 3 and 4 was the non-volatile memory. Version 3 did not store the settings (i.e. after power off the settings for MIDI channel, reference note and other parameters were lost and the unit started with Midi channel 1 and reference note 36 after the next power on). 

Version 4 had a non-volatile memory for these parameters 

The price range of the MCV1 was from around Euro 50 (kit version without case) to about Euro 90 (ready built with case).
Approximately 500 units were sold (i.e. all versions together).

Another fun fact: The guy who programmed the firmware for the MCV1 about 30 years ago showed up at the Doepfer/Alex4 booth at MusikMesse in Frankfurt this year. They had not seen each other in more than 15 years...

Doepfer USB/CV/Gate/MIDI Converters Update

A little bit more info (by Dieter himself) on two upcoming Doepfer modules popped up in the Yahoo Doepfer Usergroup today.

It said that the A-192-2 Dual CV/Gate-to-MIDI/USB Interface is in the starting blocks and will be included with the next (fall 2012) production series.
Module A-192-2 contains two independent CV/Gate-to-Midi/USB interfaces.
Another product that almost reached the production stage is the A-190-5 four voice polyphonic Midi to CV/Gate interface that will probably be included in the last production series in 2012.

The A-190-5 will have 12 CV and 4 Gate outputs, and different modes (e.g. unisono, four-fold monophonic, different four voice polyphonic modes)
The hardware of the A-190-5 module is ready and Christian is working on the firmware.
Though it was planned to use 12 bit DA converters Doepfer thinks about 8 bit converters to reduce the price a bit.
"12 bit converters don't seem to have any advantage because the module only converts 7 bit midi data into CV (no software LFOs or software envelopes or software glide) and in this case 12 bit DACs

are wasted money because the last 5 bits are not used.", according to Dieter.

The estimated price for the A-192-2 is approximately 130 Euro, expect to pay around 300 Euro for the A-190-5.

Doepfer M.A.U.S.I.

The Doepfer MAUSI (MIDI-Analog / SYNC Interface) was released in 1995 (around the same time as the A-100 system) and was a MIDI-to-CV and MIDI-to-SYNC interface to control analog vintage synthesizers, bass lines and/or drum machines via MIDI.

Doepfer MAUSI front

It was a small, half 19-inch sized grey box, and until a few weeks ago, i never realized why the Doepfer MAUSI looked so familiar to me.

An email from Dieter Doepfer confirmed that not only on the outside, but also internally this module is for 95% the same as the A-190 MIDI-to-CV/Gate/Sync Interface.

One of the small differences between these two modules is that the MAUSI had a DIN SYNC output, and the A-190 has a clock and a reset output.

Doepfer explained to me: " In modular systems the RESET feature was more popular than the Start/Stop of
the DIN SYNC, but after all it's nearly the same (just the opposite levels: Start/Stop of DIN SYNC goes high at the Start and low at the Stop, RESET goes low at the Start and high at the Stop)"

Doepfer MAUSI backside

MAUSI allowed you to control synthesizers via either V/octave (Moog, Roland, Sequential, A-100) or Hz/V characteristics (Korg, Yamaha).

Beside that, you could also switch between gate/trigger (+5...+12V) or switched trigger control (S-Trigger).

Around 400 MAUSI's were made from September 1995 until April 2000

MAUSI included an external power supply for 230V AC.

For other mains voltages the power supply had to be purchased separately by the customer. (7...12V DC/500mA with 2.1 or 2.5mm connector required).

The Doepfer Mogli and Gesture Control

In 1993 Doepfer presented the Mogli MIDI Data Glove Controller, an alternative controller device that was based on a Nintendo Power Glove controller.
It had traditional NES controller buttons on the forearm as well as a program button and buttons labeled 0-9.

The complete Mogli set with Power Glove,
receivers,  Mogli interface box and adapters

There were two ultrasonic speakers (transmitters) in the glove and you had to put three ultrasonic microphones (receivers) around your TV monitor.
The ultrasonic speakers took turns transmitting a short burst (a few pulses) of 40 kHz sound and the system measured the time it took for the sound to reach the microphones.
A triangulation calculation was performed to determine the X, Y, Z location of each of the two speakers, which specified the yaw and roll of the hand.
It could also sense the bend of the individual fingers, the only dimension it couldn't calculate was the pitch of the hand, since the hand can pitch without moving the location of the two ultrasonic speakers.

The Power Glove was originally released in 1989 and was in general a critical and commercial failure.
Partly because of the lack of accuracy and the availability of games (for it's original use with the NES)

The Mogli interface box, Power Glove and adapters

In 1993 Doepfer introduced an external box that could receive the glove's data and convert it into MIDI signals.
The name Mogli stands for 'Midi Output GLove Interface'
The original Mogli interface box was equipped with MIDI in and MIDI out, and it had a red 3-digit LED display.
The display was needed to program the unit (i.e.to assign different function to the fingers, to the X/Y/Z coordinates, to the rotating angle and so on).

After a calibrating procedure the glove could be used in different controller modes.
The 'Virtual Play' mode was maybe the most attractive mode, in which could make you play a virtual keyboard in the free space.
In Direct Mode you could assign any movement to any MIDI controller, other modes were Gesture Mode (converting sign-language to MIDI controllers) Vector Mode (position sensing only) and Manipulation Mode (for manipulating incoming MIDI with the glove).

Although i am not the world's greatest electronics-guy i do have a feeling that the original Mogli converter box could be easily transformed into a version that sends Control Voltage and/or Gate signals.

Original Nintendo Power Glove

If you can find one, it will probably just work just fine with one of Doepfer's MIDI-to-CV modules, but you might not get the most out of all the glove's many functions.

The price of the system was 598 DM (i.e. about 300 Euro) for the ready built unit including a Nintendo power glove.
The kit version was 448 DM (i.e. about 225 Euro) incl. Nintendo power glove.
The control box only (without the glove) was 398 DM (i.e, about 200 Euro)
A kit version of the box was also available for just 258 DM (i.e. about 130 Euro)

The unit was available from March 93 until December 1995, but Doepfer had to stop the production because the Nintendo Power Glove was no longer available.
Around 350 units were made in total.
Interesting fact is that the Mogli was also used by Kraftwerk (on 'Pocket Calculator' and 'Music Non Stop') during their concert at the Brucknerhaus in Linz/Austria on the occasion of the ARS Electronica Festival for Art, Technology and Society in 1993.

Okay, i admit that the technology of the Power Glove might be outdated by now, but the idea of controlling sounds/patches with the move of your hand will always stay an interesting subject.
Roland is famous for its D-Beam technology since 1998.
The A-178 Theremin Control Voltage module (or the discontinued A-179 Light Controlled Voltage Source) definitely do not offer all the functionality of a glove like this.

However, i do think we will see some kind of gesture-control-trend coming up this year with the recently announced Kinect motion sensing input device by Microsoft, that was already available for the X-Box platform but that will soon be available for the Windows platform too.
I wonder how soon the first interesting gesture-controlled modular synth-video's will pop up on YouTube...

Most Wanted VI - Special Vocoder MIDI-interface

I read the following text on one of Doepfer's A-129 vocoder system pages a long time ago, but it is still on Doepfer's website;

" A special MIDI-interface for the vocoder system is planned.

The basic functions are a 16-way CV-to-MIDI interface and a 16-way MIDI-to-CV interface (way 16 will be used for other functions like controlling slew-rate or voiced/unvoiced).

The CV-to-MIDI section converts the CV outputs of vocoder analysis into MIDI controllers which may be recorded by a computer sequencer. 

The MIDI-to-CV section converts incoming MIDI controller information into CV's for the vocoder synthesis section. 

Additionally we plan to store some factory and user definable 'vocals' in the MIDI interface so that you may call up complete vocals (like 'a', 'e', 'o', 's', 'sh' and so on) by MIDI program change events (may be we use another MIDI event type for this purpose). 

Thus the vocoder system will become a universal MIDI controlled filter system not limited to the standard vocoder features. "

Okay, i must say that it all sounds impressive and also very useful.
I do hope this module will be taken into production, but i believe this has been
on Doepfer's webpage for a while now, which makes me think that this module will probably never be made.
It might be in the Universal 12 bit AD-processor-DA module plans, because these things do need some processing power but i'm not so sure about that...
With all the announced features you could imagine this would not be a cheap module to make, but we'll see though...

How To Hide an Arpeggiator

An arpeggiator is a feature available on some synthesizers that automatically steps through a sequence of notes based on an input chord, thus creating an arpeggio.

One of my biggest personal complaints about the 'original' A-190 MIDI-CV Interface was the fact that the front-plate had the text 'arpeg.' on it while an arpeggiator function wasn't even implemented (and still not) in this module.

Doepfer recently stated that "...there were plans to add an arpeggiator when the module was designed about 15 years ago. But we found that the processor power is not sufficient to add this feature..."
He also stated that the new A-190-3 USB/Midi-to-CV module does have an arpeggiator available. ( the A-190-3 is the modular version of the Dark Link and Dark Energy USB/Midi interface, watch an 8-minute video about the Dark Energy's arpeggiator functions below ).

The same functions should work on the A-190-3 ( and Dark Link ) too, but i haven't had any hands-on time with this module to check and haven't seen much info on the web.
It does look like a very basic arpeggiator that will be hard to program, only with external MIDI-controller-messages ( like the R2M if i am correct ), but it is a good start.
I would rather see a more dedicated arpeggiator module from Doepfer, with easy accessible buttons and switches for the different settings and run-modes. Something like the Toppobrillo Quantimator (PDF) or the forthcoming Flame Chord Machine would be nice...

The weird thing though is that the whole arpeggio function is not mentioned anywhere on the module's web-page while this is such a useful function.
In fact; it's the first A-100 module that has a (basic) arpeggiator (!)

Because an A-190-3 manual isn't available yet, you can find a bit more info on how the arpeggiator works in the Dark Link manual ( PDF /page 13)*
