Interestingly enough this can be a much better solution than an installed system and of course sampled sounds.
Because it sits on top of the keys, all of the software and mechanical adjustments are in your control. Its interaction with the piano is left only to the specially designed tips (no springs). When set correctly the mechanical playback sound is imperceptible. You then have the flexibility to bring it to different pianos, work late…. Special studio user interface is also included.
