Junkmatrix – aisynthesis matrix mixer build

I was stalling this build for quite some time and after being done with it I have to say rightfully so. I still haven’t gotten too many FX in my rack and got enough mixes to build feedback loops easily. So not a must have but a fun tool to play around with. Original source: […]

Patchpals 2 – VU- Meter

I searched for a VU meter build to be able to check signals for their level. This is nothing fancy really. It basically shows the voltage of the signal. Between every diode you have a drop of approximately 0.7V so you can take that as a rule of thumb. I usually use this if I […]

Dual Buffered Multiple

I haven’t drawn the schematic yet but it is really simple: Each input goes into a buffer – voltage follower opamp circuit = signal into noninverting input, inverting input and output connected and output connected to all output jacks. Thos one uses switched jacks and the second inputs switch pin is connected to the signal […]

1:1 patchbay

When I got new equipment I needed a more space so I bought a keyboard stand that doubles as a table for performing. I’ve put my mixer there and the beatstep pro as well as a tapelooper and my FX units. To be able to patch everything into my modular I would need endless cables […]

Active Mixer – with output gainstage

This was the second active mixer I built and I wanted some more features as in the first one so I extended the first design a bit. Every channel can be muted and there is a gain stage at the output. i am really happy with this design because I have a couple of modules […]

Logic Module – AND OR NOT

This is one of my own modules and by far the simplest. I built it because I wanted logic gates for my CV and I have to say it works nicely. The AND gate has two inputs and one output, the OR gate has three inputs and one output. Both are based on diode logic. […]

Gate2Trigger – Dual G2T

This is another Bummbummsteffen Module that has served me well over the last months. I use it currently for my drum modules and sometimes for envelopes or to ping filters. A really neat addition to any system I believe. stripboard layout

PU2 – Passive Utilities 2

This module is so simple and that is what makes it so versatile as performance module. It consists only of two SPDT on-off-on switches and every pin is connected to a jacksocket. I use it mostly to prepare patches, being able to switch between CV sources mid performance/jam makes it very useful to me. You […]

quad-buffered-mult

Soo this was the first mult design I built and it served me well, but I know it is very basic. I think it was originally from a LMNC post but I couldn’t find it on his page and he had since upgraded to a design where every output is buffered which is arguably the […]
