Keyboard range

Keyzone Classic 4 is not a single piano patch. It combines multiple acoustic pianos, electric pianos and organ presets so you can move from realistic grands to brighter supporting parts inside one library.

Play and shape

Start with one of the 19 included presets, then shape the response with velocity, filter, tremolo, vibrato and ambience controls. The light presets stay immediate, while the deeper grands are there when detail matters more.

Key features

  • From grand pianos and uprights to electric pianos and organ colors in one focused library.
  • The deepest flagship programs cover the full 88-note range with layered velocity detail.
  • The shared Bitsonic Sample Player layout keeps tone, envelope and modulation shaping fast.
