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.
Price and release date are still without obligation

Doepfer A-155 Video Tutorials by Raul Pena

Last week Raul Pena celebrated one year of Doepfer demo-video-creating with a nice video.
Today he is back with a new series, this time all about the A-155 Analog Trigger Sequencer.

A-160 to A-161 Connection

Module A-161 is an eight-step Clock Sequencer which is internally connected to the Clock Divider (A-160).

Eight outputs are sequentially switched by the clock signals from the A-160 and can act, for instance, as sequential rhythmic triggers for an envelope. 

A question that popped up in the Doepfer A-100 Usergroup on Yahoo some time ago was how the A-160 and A-161 should be connected together.
This can be found in the A-161 Manual (PDF) ,but i think this post (and picture) will provide the info you need.

A-160 <> A-161 connection

The A-161 must be positioned directly to the right of the A-160.
Join the two modules with the supplied 10-way ribbon cable.
Use the upper 10-way socket on each module.
Make sure that the ribbon cable is not twisted, and that the colour-coded section is oriented the same on both modules.
Only join the A-160 to the system bus! 
Leave the lower 10-way socket on the A-161 unused.

Pay attention not to damage one of the parts on the boards (especially none of the transistors).
If necessary, you may bend the transistors a little (carefully) to plug in the cable.

MATRIXSYNTH Swag

Whoohoo!
Yesterday i got my brand new MATRIXSYNTH T-shirt, that i ordered only one week ago...
Yes, i am a fan, and i've been following MATRIXSYNTH(.com) for a very long time.
They have promoted a lot of my YouTube videos and PatchPierre articles in the past.

As a small gesture of thanks i decided to buy a T-shirt from their website, hoping they still earn a few dollars on it to keep the blog alive... (although they have ads too, unlike my own blog)
I must say the quality of shirt and print looks superb and it fits perfect too (size M)
They also added 3 cards and a nice MATRIXSYNTH magnet, but it sadly does not stick on my (aluminium) Doepfer front-plates ;-)

My new MATRIXSYNTH swag

Donations to PatchPierre (big or small) are also welcome, and possible via: http://patchpierre.blogspot.nl/p/patchpierre-donors.html, but i have no swag to give away... ;-)
Thanks in advance!

A Short Guide to Sound Synthesis by Zoë Blade

You have probably seen this next video already somewhere on the web, but i thought it was a good idea to post it here too... just in case you missed it.

" A brief guide to sound synthesis / how synthesisers (synthesizers) work. Using a Doepfer A-100 modular synthesiser, I demonstrate CV pitch and gate signals, oscillators, attenuators, mixers, ADSR envelope generators and filters."

Korg Monotron

Monotron Packaging

I've got a nice little new toy since last month;
A complete analogue synthesizer, at the size of a large Matchbox.
The Korg Monotron is a cheap (39 Euro) battery-powered synthesizer, but what a lot of fun i already had with this little thing.

It features one VCO, a real VCF (This true analog filter is taken from the classic MS-10 & MS-20 synthesizer) with Filter-Cutoff and Peak (resonance) Control.
An LFO with variable speed (and an LED that flashes in tandem) can be applied to the Pitch (VCO) or Filter(VCF)

The synth can be played on the Ribbon controller keyboard which is tiny, but can also be played with a stylus (i use an old thermometer that works perfect).

The Aux input jack lets you apply the filter to any audio source and it also has a Built-in speaker.
The headphone jack can be used for private use, but also to export the sound to your amplifier or mixing-desk.
The speaker sounds a bit chirpy (but not extremely bad), but once you've plugged it into your sound-system you really get a feeling on how good this synthesizer actually sounds.

Korg Monotron Analogue Ribbon Synthesizer

I have been using the Monotron for almost a month now, and i find it a very cool little machine.
I have it always somewhere near me... and not really as a sketchbook, but just to make funny sound effects.
The sound quality impresses me every time, considering it runs on just two AAA batteries...
I will try to add a nice little self-made Demo-video to this post if i can find the time to record one...

Another A-157 Series Update

A little bit more info on the A-157 series (or Mini-Schaltwerk) has appeared on the Future Models section of the Doepfer website.
The A-157 series is Doepfer's  trigger sequencer sub-unit with 8 tracks, and 16 steps each.

I am still looking forward to this module, ever since it first appeared on the website and on exhibitions, and i wrote about the various prototypes several times already.
Find all PatchPierre posts about the progress on the A-157  HERE

The biggest announcement is that the series will not include two, but three separate modules;

A-157-1: A button/LED control unit with 8x16 momentary switches and LEDs, 8 trigger outputs

A-157-2: A standard control unit for A-157-1, inputs and buttons for Start, Stop, Reset and Clock, memory for at least 64 patterns

A-157-3: An enhanced control unit for A-157-1 with still to be specified features (e.g. separate Clock/Start/Stop functions for each row or groups of rows, forward/backward/pendulum/random, shifting of tracks relative to the other tracks, ...)

The A-157-1 and A-157-2 are planned for the end of 2012/early in 2012, price is still unknown.

So far there is no planned release date for the A-157-3
