Our Kawai K4 sound banks are quite legendary and they truly transform the Kawai K4 (or Kawai K4R) into much better instruments than people usually think.
When you recieve the package what it contains is five unique and excellent Bitley soundbanks;
1. Analog Classics
2. New Age / Pads
3. Xtravaganza
4. Bitley 2019
5. Xtravaganza II
The package also includes a backup of the Kawai factory presets so that you have it if you ever feel for going back to its preset state. Also something you also should do if you after all decide to sell your synthesizer.
