- Tempo changes. If you wanted part of a song to be at a different tempo than the rest, then you could press a button, select the section that you want to be a different tempo, and then enter the tempo.
- Pitch bending. This should work kind of similar to BeepBox, you press a button that activates the pitch bending mode, and drag a note up or down to bend it.
- Soundfont support. This would be cool because you could get some better instruments. For example, all of the string instruments have extremely low decays, meaning that the sound doesn't last long, which is bad for imported MIDI files that use long string notes.
- Envelope editor. There would be a button that has some type of waveform, which you can edit to your heart's content.
