Hi Micco

Before you invest in an expense sample CD, please realize that you might not end up with a useable piano sound. The PSR9000 can import .wav files, so you will be able to import samples in that format. (Better than using the PSR9000 to sample audio clips of pianos). The problem is that piano "samples" are "multi-samples", that is, (good) piano samples are made of many separate waveforms that are triggered at different respective key positions and velocities. It may be that the PSR9000 cannot handle the number of distinct waveforms required for a good Piano multisample. Check on this before you invest.
