- Imbalance: Hi-hat too loud and bass drum too soft with same dynamics.
- Missing of instruments/soundfonts: Suspended cymbal, Wind chimes.
- Complicated drumset input mode: The piano keyboard contains all 'notes' of percussion but entering a note and pressing up and down keys skips some of the 'pitch' eg. cabasa. When you highlighted a pitch in drumset input mode, clicking in the piano keyboard always input that pitch.
