An analog synth voice, designed by AI
A complete analog voice with no firmware in the path: a triangle-and-square OTA oscillator, a voltage-controlled filter, an attack/release envelope from a gate jack, and an OTA VCA into headphones. Describe the voice; Ohmni wires the analog chain.

What ends up on the board
- USB-C power; analog voice on the 5 V rail, logic and headphones on 3.3 V
- Charge-pump negative rail so the OTAs swing around ground
- LM13700 VCO with a panel pot on pitch CV (triangle and square)
- OTA low-pass VCF and OTA VCA, both opened by the envelope
- Attack/release envelope from a gate jack, plus a headphone amp
How Ohmni designs it
- The voice is composed from light blocks — VCO, VCF, envelope, VCA — not a single synth-voice IC.
- Supply spans are checked (the LM13700 needs at least 4 V across the rails) and the layout is rule-checked before you see it.
- You download gerbers, a BOM, and a 3D preview, ready for your fab.
