Hello everyone. After working a lot on the 8bit music app(which I decided to call tonnoform), it's available as a beta! Here's the github link: https://github.com/Nikos1001/Tonnoform

Please try it out. I compiled it for Mac and Windows. Here are the app's controlls:

MIDI EDITOR(the tab called "Track"):

+: create new pattern

-: delete pattern

UP / DOWN: arrow keys: scroll pattern up/down

W / S: scroll pattern list up/down

click in pattern editor: create new note

drag note in pattern editor: extend / unextend note

right click note in pattern editor: delete note

click in sequencer: place selected pattern

right click on pattern in sequencer: remove pattern

click on instrument name in sequencer: switch instruments

INSTRUMENT EDITOR:

+: create new instrument

-: delete instrument

W / S: scroll instrument list up/down

drag rectangles in the middle: edit instrument envelope
