VIC-20 MIDI SEQUENCER

This is a simple 16-step MIDI sequencer written in BASIC for the Commodore VIC-20. It is using the VIC-20 MIDI cartridge from RETRO Innovations.

There is a short demo video over on YouTube

Installation

Copy the file vicseq.prg over to your favorite device to get data onto the VIC-20, eg. SD2IEC or Pi1541 floppy disk drive emulator. A memory expansion needs to be in place in order for the program to run.

Start it with the following commands:

LOAD"VICSEQ.PRG",8
RUN

Replace the device number accordingly.
