ØCHD-OBER-FEST (live event) with DivKid, Instruo & Signal Sounds // ochd expander launch party

video upload by DivKid

"In case you missed the live stream at the time, made it but would like to watch again, or were even at the in person event itself and wish to relive the beer, pretzel and modulation good times... here's a fresh 4k HD edited version of the OCHD-OBER-FEST event that myself (DivKid), Instruo and Signal Sounds had back in October 2023 to launch the new ochd expander.

I've also just put up a new video with the case and patch that I set up for this event. This was filmed more long form and in detail when I got back home. It's a polyphonic, generative ambient piece that makes use of lots of ochd and it's expander. Check it out here // [below]

If you'd like to support work like this and the wider range of what I do, considering heading over to Patreon at and supporting for as little as $1 a month to gain access to the DivKid Discord community, plus lots of exclusives such as PDF patchbooks, videos and more.

The patch that launched the OCHD EXPANDER // Polyphonic Generative Ambient Eurorack Modular

video upload by DivKid

"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."
