Description
Each sketch lives in its own folder and documents its pin assignments for the MOD1's pots, jacks, button and LED. Others in the repository are a simple knob-to-CV and latch utility, a one-button drum sequencer, a CV sequence recorder marked as work in progress, and MS-20 converter sketches. The percussion sketch modifies another builder's dual attack-decay design to behave like the Befaco Percall.
Install notes
Open a sketch in the Arduino IDE and upload it to the MOD1's Arduino Nano. If uploads fail, the MOD1 build page suggests switching the processor option to the other ATmega328P bootloader setting.
