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

SYNTH-MIXER6-01
Eurorack 6HP
Adapted from HAGIWO's 5 Channel Mixer Module

RP2040 VCO

SYNTH-VCO-03
Eurorack 6HP
(3) Card set
Views: Control Panel rear side, Control Panel controls side, Logic card component side, Logic card rear side, Front Panel

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

Eurorack DIY Panel

Front/Back View
Left = top

Based on HAGIWO design

6HP wide
3U tall
Power and Ground bus on either side of the card
Reduces wiring
Slotted mounting holes
5mm Grid on rear side makes it easier to locate connectors for drilling
