- Volume and Voices — more voices cost more CPU.
- Semi and Detune (±50 cents).
- Stretch — stretch tuning. Real tines and strings don't behave like the ideal model, so equal temperament can sound off on pianos; stretching sharpens high notes and flattens low ones. Negative values do the reverse.
- Pitch Bend — global bend range; Note PB — MPE per-note bend range.
