midi88 lets you press lower and higher keys in the virtual piano, by clicking the control key. Usually, Roblox pianos only have five octaves on the piano, but a lot of songs use seven octaves. So when you are autoplaying with midi88, the song will sound a lot more full because it will be using the full seven-octave piano. The downside is that only some games support the usage of midi88, some of them being: Visual Pianos, Piano Rooms, Tac's Piano Stuff
MIDI2LUA is branched off of TALENTLESS, a Roblox script that autoplays the virtual piano by injecting fake keystrokes. MIDI2LUA extracts the rest intervals between notes in your MIDI file and converts them into a custom LUA format, which was also created by hellohellohell012321 and is used in his script, TALENTLESS.
