We are working on a build guide – it should be online next days.

Please download the BILL OF MATERIALS REV1.1.0 and FIRMWARE REV1.0

to program the unit:

  1. flash the bootloader using STLink
  2. turn DD off, then turn on holding SHIFT button – unit should start in USB device mode
  3. connect to your computer via USB, DD should mount as a flash drive, format it as FAT32, put both firmware and presets file to
  4. reboot the DD, get to settings (SHIFT + CANCEL), then perform a reset to defaults, then get to calibration menu, calibrate sliders first and oscillators after. Initial oscillators calibration takes ~15 minutes.
  5. Synth should be working

synthCube has full parts kits in stock.
