  • Tone generation: variable oscillator assignment options, two new operating modes (dual oscillator and single oscillator)
  • Polyphony: max. 32 voices
  • Sounds: 500 sounds and 100 ROM performances
  • Sequencer: the sounds can be edited while the sequence is running, LFO can be synchronized with MIDI clock
  • Internal memory: A battery-backed RAM disk can be set up (with additional memory modules)
  • Sample features: Sample Translator integrated into the operating system, import of samples in many formats, Akai multisamples are read (no sound data)
  • MIDI: Compatible with the GM and Roland GS standards
