A MIDI-to-TIC-80 converter.

"The mission, the nightmares... they’re finally... over." - CT-5385 (presumably about switching to TIC-MIDI ;) )

• Utilizes up to all 4 audio channels simultaneously
• Has variable audio resolution to use more or less space in exchange for audio quality
• Can map midi tracks to sfx as dictated by the user, allowing for different instruments
• Has variable volume
• Sets tempo and speed to match input
• Can insert music into existing cart
• Can use any memory bank

• Can only write a single file to a single track
• Disregards multiple MIDI channels
• Only considers the following MIDI messages: set_tempo, note_on, note_off
• Only uses the Master Volume TIC-80 command
• Does not generate sfx and waveforms

Make sure Python (3.8+) is available on your system.

Install the dependencies:

$ pip install -r requirements.txt

Then, simply invoke the script:

$ python tic_midi.py input_file -o output_file

To learn about the settings you can use, invoke the script with the -h flag:

$ python tic_midi.py -h

When playing the music with your lua code, set sustain=true in your music function call, since the converter currently doesn't re-play notes when starting a new frame.

A sample MIDI file, and the cartridge produced with it, can be found in the example directory.
