I love to make Kontakt pianos, but I think I've run out of Public Domain and Creative Commons piano samples. I've just done the OLPC samples, already used the Iowa Samples, converted over the Salamander and all the Musyng Kite Sound Font pianos which Sarcyan kindly let me do. I found lightly sampled but fun Upright and Prepared piano samples. Does anyone know of any more out there with PD or CC type licenses?
The Maestro Grand while a vintage free piano is copyrighted, otherwise I'd convert that to Kontakt in a heartbeat.

 

you could have a look here,but id say you been there already ?
