OscPocketD/Base - VA synth with multi FX and CV/Gate in/out

StaffanMelin · July 30, 2021, 6:27pm

Finished the OscPocketD/Base - it is a two voice monophonic VA synthesizer and multi FX unit, with 2 CV in, 2 Gate in, 2 CV out and 2 Gate out (as well as LFOs) for modulation. All code is running on a Daisy Seed. Effects are Filter, Gate, Bitcrusher, Overdrive, Delay, Chorus and Reverb. It will also serve as a hardware bed for sonic exploration.

In the photo the oscillators are controlled by CV0 in connected to CV1 out which outputs the 2nd potentiometer value!

This is a development and aggregation of stuff I learnt while making the

I’ve started to work on a sister unit with MIDI in. After that one is finished I will publish code and build instructions in case anyone is interested.

Any audio examples we could listen to / demo video we can have a look at ?

@Sef, thank you for your interest! I will make a video when I’ve finished the MIDI-version and put together the build instructions (+ code, GPL’ed). The FX part is the same as for the OscPocketD/FX: https://youtu.be/fKHz_6E0YFA.

THe CV operates at 3v3, but this still makes it useful for modulation and control, as well as 3+ octaves of CV pitch control (and kept the electronics simple and within my knowledge horizon! ). All ins are protected against overvoltage, though.

Midi is now working on the sister build.
