Synth Modules

Synthesizer interfaces and modules
- MIDI-IN-OUT - MIDI In/Out
- SCF-2 - Dual 3.5mm Audio Jacks (Scale, Clip, Filter_
- SYNTH-VCO-01 - Synth Voltage Controlled Oscillator
- SYNTH-MIDI-CTL-01 - Synth MIDI Controller
- SYNTH-MIDI-CV4-01 - 4 Output MIDI to CV controller

MIDI-IN-OUT

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)

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 - Synth Voltage Controlled Oscillator

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
- Stacks with SYNTH-MIDI-CTL-01 card

SYNTH-MIDI-CTL-01

SYNTH-MIDI-CTL-01 - Synth MIDI Controller

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
- MCP4822 12-bit D/A - SPI Interface
  - MCP4822 Datasheet
- Use with SYNTH-VCO-01
  - CV1 = V/OCT
  - CV2 = MOD
(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
- Stacks with SYNTH-VCO-01 card

SYNTH-MIDI-CV4-01

SYNTH-MIDI-CV4-01 - 4 Output MIDI to CV controller

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
- MCP4822 12-bit D/A - SPI Interface
  - MCP4822 Datasheet
- Use with SYNTH-VCO-01
  - CV_1 = V/OCT
  - CV_2 = MOD
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
- Stacks with SYNTH-VCO-01 card

6 Channel Mixer

Eurorack +/- 12V Power Supply

115VAC in, 24V CT, 24 VA Transformer
- 12*1.414 = ~17V
  - Leaves 5V for regulator headroom and ripple
L7812CV, +12V, 1.5A Regulator
L7912CV, -12V, 1.5A Regulator
