Scratch is really slow at running this project; try it in Phosphorus for better performance: https://phosphorus.github.io/#172620559 The MIDI file I used for this is the ending theme of Dragon Quest IV; I got it from the Dragon's Den: http://www.woodus.com/den/music/midi.php (The song is long; give it a moment or two to get going..!) I used midicsv to convert the MIDI file into a CSV, then fed that into my own program to generate a tosh script: https://gist.github.com/towerofnix/eafeb4de9cfb3ab8056cf5a3f686f956 (If you use it, you'll probably have to change the "fake tempo" variable.)
