Doepfer NAMM 2018 A-100 Standard Module Announcements

A-123-2
My third and last post about the New Doepfer announcements for NAMM 2018... (January 25/28 2018, Anaheim, Hall A, booth 10706)
The other 2 blogposts are about the  Dark Energy III and their new Polyphonic Modules...
Among the newly announced "Standard Modules" there are these little gems

The A-123-2 6/12/18/24dB Highpass Filter is an interesting voltage controlled highpass filter with four filter outputs (6, 12, 18 and 24dB slope). It also features voltage control of the resonance. These controls and in/outputs are available:
• Audio In with attenuator (Lev)
• Manual Frequency control (Frq)
• FCV1: Frequency control input (~ 1V/oct)
• FCV2: Frequency control input with polarizer
• QCV: Resonance control input with attenuator
• Manual Resonance control (Q)
• 6dB Output
• 12dB Output
• 18dB Output
• 24dB Output

A-140-2
The new A-140-2 Dual Micro ADSR
contains double ADSR type envelope generators behind a front panel with 8 HP only. Each ADSR provides these controls and in/outputs:
• Attack (A), manual control
• Decay (D), manual control
• Sustain (S), manual control
• Release (R), manual control
• Gate Input
• Retrigger Input
• CVT Input with attenuator (CVT = CV Time)
• Envelope Output 1
• Envelope Output 2
• LED control

By means of internal jumpers one can select which parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question). By means of another jumpers output 2 can be set to normal or inverted envelope).
Two more jumpers are used for the optional bus
access to the gate signal of the bus for each ADSR.

A-142-3
A-142-3 Envelope Controlled VCA Module A-142-3 is the combination of a simple AD/AR envelope generator and a VCA behind a front panel with 4HP only.
The type of envelope can be selected by means of a toggle switch between A/D (Attack-Decay) and A/R (Attack/Release). Another toggle switch is used to choose envelope or (free running) LFO mode.
The envelope output controls a linear VCA.
These controls and in/outputs are available:
• Attack control
• Decay/Release control
• AD/off/AR switch
• Envelope/LFO switch
• LED (envelope display)
• Gate Input
• Manual gate (momentary switch)
• Envelope Output
• VCA CV Input (normalled to Envelope Output)
• Audio Input with Level control
• Audio Output (the outputs of several A-142-3 can
be internally mixed together)


Furthermore, the modules that were already announced at Superbooth 2017 like the A-138s Mini Stereo Mixer and A-150-8 Octal Voltage Controlled Switch will be available pretty soon now...  and the A-180-9 got a final facelift and got upgraded from 12 to 14 channels through standard network cables.

Mutable Instruments Peaks Demo by DivKid

Another lnice and long Eurorack demo by DivKid, demonstrating the multifuncional Mutable Instruments Peaks module.

" Peaks is a multi-function module, but the general rule is that cool things happen whenever a trigger
is received. Its four main functions are:
Envelope generator – the gate/trigger input starts and holds the envelope.
LFO – the gate/trigger input resets the waveform cycle.
LFO with tap-tempo synchronization – the gate/trigger input sets the period of the LFO oscillations. Note that Peaks can “learn” irregular trigger sequences and lock onto them.
Drum generator – the gate/trigger input triggers the drum sound.

Peaks provides two channels of processing – each of them has a gate/trigger input jack, a gate/trigger button with an output indication LED, and an audio/CV output. Both channels provide the same function – the exception being channel 1′s drum generator being a bass drum generator, and channel 2′s drum generator being a snare drum/hi-hat generator.

Both channels can be “synchronized” (aka twin mode), in that they both share the same front panel controls – for example in ADSR envelope mode, the first knob will control both channel 1 and channel 2′s attack time. This can be used not only to create duophonic patches (for which you actually want both channels to behave similarly), but also to obtain two synchronized outputs of the same LFO waveform with different phase shifts…

Another way of controlling the module is the split mode in which the potentiometers 1 and 2 control channel 1′s settings; and the potentiometers 3 and 4 control channel 2′s settings. This mode only gives access to the 2 most essential parameters of each function (for example attack and decay time for an envelope) – the other parameters being set to default “neutral” settings.

Finally, if breaking the one knob per function rule is not a taboo for you, an expert mode allows individual control of channel 1 and 2."

" Another hugely feature packed module from Mutable Instruments! Peaks has 4 modes with envelopes, LFOs, Tap-LFOs and drums then an additional 4 'hidden' modes which are a mini step sequencer, trigger delay and repeater, trigger stream randomiser and a dual Anushri style synth drum generator.
As always all comments are welcome!

New A-141-2 Voltage Controlled ADSR/LFO Announced

A-141-2 Voltage Controlled
ADSR/LFO
Doepfer announced another new module this week.
The A-141-2 Voltage Controlled ADSR/LFO will replace the old A-141 module that is running out now. (the last ones are on sale)

The newly announced 14 HP wide A-141-2 Voltage Controlled ADSR/LFO will be similar to the A-141 but it has a lot of extras/ improvements.
For example it has a common CV input for all time parameters (A/D/R), a 3-position range switch for time range 10:1:100 and digital outputs for EOA (end of attack) and EOR (end of release).

It also has three envelope outputs: one with fixed ADSR, one inverted output and a third output with additional CV input for level (i.e. built-in level VCA)
There's also the possibility to change the shape of each segment of the envelope (exponential - linear - inverted exponential), it has a VCLFO mode and is planned for summer 2013

The price will be around 125.00 Euro, price and planned release date (August 2013) are still without obligation !

A-143-2 Quad ADSR - Power to the Quads!

Good value-for-money and serious rackspace-savers are Doepfer's Quad modules.
These modules offer four (-duh-) identical but individual modulation sources in one module.

My A-143-2 Quad ADSR is at the heart of my A-100 system.
With 4 envelope generators in one this is a very powerful module, and this is where the 3 individual gate outputs from my MAQ 16/3 come together.
Also see THIS post.

The Gate inputs of the units 2, 3 and 4 are normalled to the Gate input of unit 1, so Gate input 1 is connected to the switching contacts of the Gate input sockets fom submodule 2, 3 and 4 if no other input is connected.
With only one Gate signal applied to Gate input 1, it can be used to trigger all four sub-modules simultaneously.
A switch for each individual channel is available for switching between high, low and medium ranges.

All 4 sub-units have additional input sockets for Re-Trigger, but the re-trigger behaviour of the A-143-2 is slightly different compared to other envelope generators;
During the attack phase the envelope cannot be re-triggered or reset. (unlike the A-140 ADSR envelope, that envelope can be re-triggered while the gate is still open).

Each sub-unit also has three digital outputs (high/low) that sends a trigger signal at the End of Attack (EOA), End of Decay (EOD) and End of Release (EOR).
This is very useful if you want to daisy-chain the sub-modules to create more complex envelopes. (or even complete loops)
The envelope outputs are displayed with LEDs and the maximal envelope voltage (Attack/Decay reversal point) is about +8V.

The Quad series consists of the following Multiple modulation sources so far;
A-143-1 Quad AD, A-143-2 Quad ADSR 
A-143-3 Quad LFO
A-143-4
Quad VCLFO/VCO
 (just released), A-143-9
VC Quadratu
re LFO and modules A-142-4 Quad Decay, plus Quad Amplifiers A-132-2 Quad VCA I and A-132-4Quad exp. VCA

A-140 ADSR Envelope Generator

Perhaps i should have started my whole PatchPierre blog with writing about the most basic and essential A-100 modules first.

How the four parameters A, D, S and R
change the shape of an ADSR envelope
The A-140, Doepfer's envelope generator was released back in 1995/96, and was one the first modules available.
It is a simple ADSR (Attack, Decay, Sustain, Release) generator.
When this module is triggered it generates a variable voltage, changing in time, called an envelope.

The shape of the envelope is set by four variable parameters: Attack, Decay, Sustain and Release.
The envelope is started (triggered) by a gate signal either from the internal gate voltage on the system bus or, if a signal is put into it, from the gate input socket.

The varying voltage (visualized by an LED) is output in normal (positive) and inverted form, and can be used for all kinds of voltage controlled modulation of any VCO, VCF,  VCA or other CV controlled inputs.
The envelope can also be re-triggered, but that only works when the gate is opened.
The module  has a three-position toggle switch between three time ranges.
The envelope time can be set from about 50 microseconds up to several minutes.

Okay... There's not much extra to write about this elementary module, although i do like the inverted output (plus that it has two 'normal' outputs).
I should say that there are more economicly priced other envelope generators available.
My advice is to get yourself one of the Quad envelope generators for example... if your modular gets bigger you will probably need more EG's anyway.
I do have the four-fold A-143-2 Quad ADSR, but the A-143-1 Quad AD with only Attack and Decay, or perhaps the A-142-4 Quad Decay with just decay are just a few of the other options if you are looking for expanding your modular with basic EG's...
