🍑 PEACH – Dual Digital Unison VCO

Code & Core Design by HAGIWO

PEACH is a compact, expressive 4HP digital oscillator designed around HAGIWO’s brilliant open-source dual-VCO architecture. Powered by the Seeed XIAO RA4M1 microcontroller, it delivers rich, detunable unison textures, punchy wavetable timbres, and modular-ready voltage control—all for an incredibly low cost, power and space footprint.

We took HAGIWO’s open schematics and software, built a custom PCB, and wrapped it in a star-studded matte black panel with our signature flair.

✨ Features:

• Dual Oscillator Architecture
  OSC1 provides the base frequency while OSC2 brings variable detuning (up to 2 octaves) and level control for thick, layered unison tones.

• 16 Wavetable Waveforms
  From harmonically rich to glitchy digital goodness, all switchable via a dedicated push button. The selected waveform is stored in EEPROM.

• Voltage Control

  • 1V/Oct input for pitch tracking

  • CV input for OSC2 level—dial in evolving textures with envelopes or LFOs

• Front Panel Controls

  • FREQUENCY knob (OSC1)

  • DETUNE knob (OSC2 relative pitch)

  • OSC 2 LEVEL knob

  • Waveform selector button

  • Outputs a 10Vpp audio signal, Eurorack-ready
