[$9] DIY eurorack modular synth Arduino Unison VCO w/ Seeed XIAO RA4M1
video upload by HAGIWO
"My 83rd original eurorack modular synth DIY projects.
Seeed XIAO RA4M1 based Dual Oscillator VCO.
You can create a thick sound by using detune or adding a 5th.

"Specifications
Eurorack standard 3U 6HP size
Power supply: 10mA (±12V), 20mA (5V)
2-oscillator digital VCO using Seeed XIAO RA4M1.
Supports V/oct, and the waveform can be selected from 16 types of wavetable.
The frequencies of OSC1 and OSC2 are always in a relative position relationship, and detune and overtones can be added by shifting the frequency of OSC2.
OSC1 FREQ POT: Adjusts the reference frequency of OSC1 and OSC2
OSC2 FREQ POT: Adjusts the frequency of OSC2 relative to OSC1. Can be set from 0 oct to 2 octs above.
OSC2 volume POT: Adjusts the volume of OSC2
OSC2 volume CV in: CV input for adjusting the volume of OSC2
Wave push SW: Selects the wavetable. 16 types in total.
V/oct IN: V/oct input, range is 0~5V.
OUT: Audio output, range is Vpp10V.
The selected waveform information is stored in EEPROM. When the power is turned on again, the last selected waveform is selected."
