- attack is too slow compared to original, the punch is missing
- envelopes don't go as far as original does
- sliders don't poll often enough, fast tosses cause stepping
- arpeggio range switch contains only 2/3
- octave switch has only two values, neither of them do anything
- tuning switch doesn't have effect on sound
- arpeggiating notes causes clicks
- setting cutoff to max and lowering it causes a low peak of volume, same applies to envelope
