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).

Find more info in the English User's Guide of MAUSI.

DIY Modular Case Ideas

There are many ways to house your (eurorack) modular synth, i wrote about the pre-manufactured options from Doepfer earlier, find that post HERE, but of course you can also try to build you own case.
There are many ways to make your own A-100/Eurorack case if you start out with just the basic rails and busboard, and you can make it as cheap or expensive as you can.

Check out a few ideas;
Wooden cabinets and side-panels are still very popular amongst (modular) synth enthusiasts.
These simple case standards for the pre-manufactured LC9 cases are very simple, and can be sooo useful

Matthew Goike (@Goiks) also has some nice wooden cabinets on display and for sale on his website: http://www.goike.com/node/5

...or do what Stretta did (or rather what his brother did), make a high-end wood/brushed aluminium cabinet with integrated LED-lights and some …

Doepfer A-150-8 Octal Manual/Voltage Controlled Programmable Switches Announced

Doepfer has just released some info on their new modules for NAMM 2017 (19-21 jan.) Besides some vintage editions of existing modules, the A-135ABC VC Performance mixer modules, the A-110-6Trapezoid Thru Zero Quadrature VCO and a new A-100LC1 case (economically priced small housing with 48 HP width) there was also one other interesting new module announcement:
Module A-150-8 contains eight manually/voltage controlled switches.  Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2).  The switches are bi-directional, i.e. they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. 
Two LEDs show which in / output is active (ie. which is connected to the common out / input).  In addition the LEDs are used for the programming of the module: For each unit the operating mode can be selected:  Toggle or Level controlled. In Toggl…

Happy New Year From PatchPierre

Hi there, it's me again... Happy New Year!

You might have noticed that I havent posted a lot in the last 2 years...
It's been a rough time for me since the sudden loss of two parents within a relatively short time-span and I really needed some time to get myself together... to set things straight, finding myself and selecting priorities... even my regular work suffered from this breakdown.

It took a while to understand it all, and to get a better grip on it, and it's sometimes still not very clear.
I think I have found a way to cope with most of it now... although the slight autism that I have (ADD-like) doesn't make it easy for, especially in crowds with lots of people I don't know...
On my journey I also (re-)discovered the beautiful woman that has always lived inside of me and that i need to accept and cherish... more on that maybe later... I'm not considering changing the name of the blog to PatchPetra.Net 😇 (...yet), but you might spot me somewhere at mod…
