Synth Modules

MIDI-IN-OUT

MIDI-IN-OUT REV1 FRONT 3D.png

  • MIDI-IN-OUT - MIDI In/Out
  • MIDI In/Out Jacks
  • 5V MIDI
  • 3.3V or 5V Serial connections
  • MIDI In is opto-isolated
  • (2) 4-40 Mounting holes

SCF-2

  • SCF-2 - Dual 3.5mm Audio Jacks (Scale, Clip, Filter)

SCF-2 REV 1 FRONT 3D.png

  • Digital Inputs or Outputs
  • (2) 3.5mm Jacks
  • Scaling resistors
  • Schottky Clamping Diodes
  • Filter cap
  • Ring pin brought to connector
    • Ring pin is not used in Synth applications
    • Card can be used as a 3.5mm breakout
  • (2) 4-40 mounting holes

SYNTH-VCO-01

SYNTH-VCO-01 REV1 FRONT 3D.png

  • Build of Pico VCO by HAGIWO
  • Digital Voltage Controlled Oscillator (VCO)
  • Three modes: Wavefold, FM and AM
  • PWM output with 2 pole low pass filter
  • Each mode has eight built-in waveforms
  • XIAO RP2040 CPU
  • (5) Pushbuttons
    • Octave Up/Down
    • Mode Up/Down (Wavefold, FM and AM)
    • Push Timbre switches between 8 waveforms
  • (2) Knobs
    • Freq fine adjust
    • Mod adjust
  • Standard EuroRack 16 pin header
    • Supports 12V in with on-board 5V regulator
    • 5V regulator can be not installed if 5V is available on EuroRack connection
  • Card is not a Eurorack card
    • Probably too deep, needs cabling
  • (4) 6-32 mounting holes

SYNTH-MIDI-CTL-01

SYNTH-MIDI CTL-01 REV1 FRONT 3D.png


  • Adapted from HAGIWO's MIDI to CV module
    • Translate from Japanese to English using browser
  • XAIO RP2040 CPU
    • Arduino MIDI library has not yet been ported to Pico so will need to use CircuitPython
  • MIDI In/Out
    • Standard MIDI Jacks
    • MIDI out jack for future functionality
  • (2) 0-5V Analog CV outs
  • (2) Digital Outs, eX:
    • Gate
    • Clock
  • Pot supports setting Clock rate
  • Standard EuroRack 16 pin header
    • Supports 12V in with on-board 5V regulator
    • 5V regulator can be not installed if 5V is available on EuroRack connection
  • Card is not a Eurorack card
    • Probably too deep, needs cabling
  • (6) 6-32 Mounting holes

SYNTH-MIDI-CV4-01

  • Adapted from HAGIWO's MIDI to CV module
    • Translate from Japanese to English using browser
    • Removes Digital Outputs
    • Has 4 Analog Outputs instead of 2
  • XAIO RP2040 CPU
    • Arduino MIDI library has not yet been ported to Pico so will need to use CircuitPython
  • MIDI In
    • Standard MIDI Jacks
    • MIDI out jack for future functionality
  • (4) 0-5V Analog CV outs
  • Standard EuroRack 16 pin header
    • Supports 12V in with on-board 5V regulator
    • 5V regulator can be not installed if 5V is available on EuroRack connection

Projects

  • elkayem midi2cv GitHub page - Nano based project
    • Arduino MIDI library has not yet been ported to Pico so will need to use Python
    • Drives 4 CV outputs: Pitch Blend, Control, Note, Velocity
    • This card only drives Note (Voltes/Oct, Mod)
  • PicoPicoSynth
