Hi if you wanna use this it's in a super mega testing phase rn, but run " python3 -m midi_editor.app " in the app folder and it will launch. controls are scroll wheel to scroll view, CMD +scroll to zoom x axis and ALT +scroll to zoom the other axis. just have import a midi file mess around and have some fun this is not a real build.
Install it like this: git clone https://github.com/Hackerman696/Porymusic cd python3 -m venv .venv source .venv/bin/activate python -m pip install -U pip pip install -r requirements.txt
run it like this from the root: python -m midi_editor.app
