Requirements

• abc2midi - https://abcmidi.sourceforge.io/
  • brew install abc2midi
  • if not installed using homebrew set path here: https://github.com/supersational/JAMMIN-GPT/blob/main/generate_midi.py#L15
• pip install openai>=1.1.1 rtmidi mido==1.3.0
• place 'client' folder in Ableton's Remote Scripts folder (for me it's in /Users/sven/Music/Ableton/User Library/Remote Scripts/AbletonOSC/client/)

Optional Requirements:

• fluidsynth (to use GM soundfonts)
  • run fluidsynth and select it as an output MIDI device in Ableton with 1 channel per track
  • fluidsynth path_to_soundfont/FluidR3_GM.sf2 -pFluidSynth is the command I use

Screenshot

Add AbletonOSC as a control surface in Ableton

Run the python script

In a seperate terminal window run:

python main.py

• You should see the output: waiting for named MIDI clip to appear..
• Now create an empty MIDI clip in Ableton and rename it something like: "piano arp"
  • Create MIDI clip shortcut: cmd+shift+m
  • Rename MIDI clip shortcut: cmd+r
• If the script works correctly the clip's name should change
• The MIDI clip should now contain LLM-generated music, make some more!

Debugging

• Make sure you have added AbletonOSC as a control surface in Ableton
• Sometimes there is an orange colored message in the bottom status bar of Ableton
• There are ways to debug remote scripts in Ableton and see print statements, guides can be found online
