Keyzone Classic 4

Bitsonic has announced the release of Keyzone Classic 4, a focused keyboard collection for the Bitsonic Sample Player.

Keyzone Classic 4 combines acoustic pianos, electric pianos and organ tones in one ready-to-play library. It is designed for quick playing, songwriting and production work instead of endless patch hunting.

The collection includes 19 presets, from deeper grand piano programs to lighter keyboard sounds such as Bright Piano, Triton Piano and Hammond. Concert Piano, Steinway B and Dark Grand cover the full 88-note range, with the flagship Concert Piano using four velocity layers per note.
