Here we have a detailed run down of the patch that launched the expander. I brought this case and exact patch back from my journey up to Glasgow for the OCHD-OBER-FEST live event with Instruo in Signal Sounds. We launched the ochd expander at that event and this patch was my demo for that event. Note – you can check out the live event re uploaded and editing in 4k below.

This is patch is a 4 voice, polyphonic generative ambient piece that uses 4 wavetable oscillators into 4 VCAs for heavily modulated chordal sound sources. That is then tone, drive and level modulated before feeding two FX with a novel patch routing. It’s highly dynamic, from near silent quiet sections to loud sections. All that dynamism comes from ochd and the ochd expander.
