PSYC03
PSYC03, alias PerCussive SYnth 03, is the result of the combination of a Syncussion and a TB303, an acid percussive synth.
It is based on Motherboard9.
NOTE: This is a work in progress.
Features
- 3 shapes
- Acid style filter
- Filter with LFO
- FM
- MIDI over USB
- MIDI over mini jack
- Audio jack output
Dimensions
Height: 3U / 128.5mm
Width: 12HP / 60mm
Getting Started
Prerequisites
What things you need to make it work:
1 Teensy 4.0
1 Teensy audio board
1 MOTHERBOARD9A pcb
1 MOTHERBOARD9B pcb
1 PSYC03 front panel pcb
9 vertical linear 10k potentiometers
3 14 pins male header
5 14 pins female header
6 CD4051 multiplexers
6 DIP16 IC sockets (optionak)
2 3.5mm jack connectors
1 resistor ~ 22ohm
1 LED
1 4 positions dipswitch (optional)
I personally get these parts from multiple stores: digikey.com, thonk.co.uk, modularaddict.com
In order to run any sketch on the Teensy you have to install the Teensyduino add-on to Arduino. Follow the instructions from the official page: https://www.pjrc.com/teensy/teensyduino.html
Then open the sketch located in the Synth folder of this repo.
In the Tools -> USB Type menu, choose "Serial + midi".
Then you are ready to compile and upload the sketch.
How to use
Here is a description of the 6 inputs and what they do:
1. Shape
1. Sine
2. Triangle
3. Square
2. Tune
3. Sweep
4. FM
- Modulator frequency and amplitude
5. Attack (0 to 2000ms)
6. Release (0 to 2000ms)
7. Cutoff
- Low pass resonant filter
8. Speed
- Frequency of the filter LFO
9. Depth
- Amplitude of the filter LFO
MIDI
The MIDI input and output jacks are directly connected to the Teensy serial input and output. That means there is not protection against voltage or current. It is primarily ment to connect 2 of these modules, or 2 Teensy together. If you want to connect something else to it make sure to provide a maximum of 3.3v and 250 mA.
