Xpand!2 is a multitimbral workstation offering four active sound slots, or parts, per patch. Each part is provided with its own MIDI channel, Note Range (Zone), Mix, Arpeggiation, Modulation, and Effects settings—an excellent method for creating individual parts.

Harnessing the four parts together to build one amazing Patch is where Xpand!2 reveals its true power. The Voice Mode for each part can be set to polyphonic or monophonic. Polyphonic parts can have up to 64 voices; monophonic parts offer First, Last, Highest, or Lowest priority making it easy to designate a bass, lead, or solo instrument.
