A-165 Dual Trigger Modifier

The A-165 Dual Trigger Modifier contains two separate and identical trigger modifiers for use with logical / digital levels.
In fact it works pretty similar to the A-175 Dual Voltage Converter, only this module works on Gates, Clock and Triggers.

Each half of this module enables signals, generated by the A-100, to communicate with other instruments (such as an external sequencer), or is simply used for reversing a trigger's polarity.
Whatever signal is patched into the input is inverted by the module, and fed out of the Inv. Out (inverted output) socket.
At the same time, a short trigger signal (of roughly 50 ms) is generated every time an edge of the trigger pulse is sensed (negative as well as positive).
This trigger signal is available at the +/- output.
Two LEDs show the level of signal available at the two outputs.

Because the original and inverted trigger signal are often both needed at the same time, it is possible to use these two inputs as a mini-multiple - using one of them to send the original trigger to another module.

The A-165 manual has a few interesting patch-examples, but i use it the most in combination with my A-160/A-161 Clock Sequencer/Divider combo to mess up my rhythms.

If you are only looking for simple trigger inverters, you might want to take a look at the A-166 Dual Logic module which also has two simple inverters, only minus the  +/- pulse that the A-165 has.

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…
