Just your average MIDI composer. I like to make Black MIDI pieces (not the band, the genre) that have lots of notes. Many of these are not playable here or cause intense lag. Download their MIDI files and play them on a program on your device if you want to listen to them. I've made many over the 1,000,000 note limit, which sadly are not possible to share here. Sometimes I also remix existing songs or just mess them up.
