Chopin Piano Rolls in MIDI format

By far the best (meaning most accurate) publicly available Chopin piano rolls are those painstakingly encoded by Peter Phillips. His website, where selections can be purchased is at www.petersmidi.com

 

There are several selections available and Peter welcomes enquiries on individual requirements. The package of Romantic Piano Music at $40 (U.S.) contains many Chopin MIDI files and I can confirm that these can be realised using a good quality sampled instrument (see below, which uses the Hammersmith piano, with additional high-end reverb and mastering tools).
