THANK YOU, liszt1022 for making available the entire set of "The Pianist" performances by PG music. I had purchased the Valery Tryon set of 300+ performances of Classical Piano pieces released in the mid 1990s on floppy disc and I extracted the midis for use in my Pianodisc grand piano. Her performances are uniformly excellent and now, to have courtesy of you, several hundred more by other pianists as well, is truly wonderful.
Pianodisc offer a free program (app) called MusiConnect which converts the midis to .wav to drive the piano via the rear of its CD player, but far superior and very much more realistic reproduction is achievable by playing direct from raw mid thru the midi-in port. I have a Mac computer and open and play the midis from MidiSwing, a free app (which I'm told does not work as well on PC). A USB to midi cable connects my computer to the piano. I am able to convert Type 1 midis to Type 0 and to quickly adjust note velocities throughout an entire midi to optimise the reproduction out of my piano, as the original unaltered midis would otherwise play back far too loudly. MidiSwing also permits me to edit sustain pedal, correct wrong notes and adjust tempi throughout. In fact, I am now able to successfully emulate favourite performances of piano works I have on CD, simply by manipulating these parameters, bar by bar through the entire piece.
Another immensely rich source of classical piano midis is the thousands scanned from piano rolls for made for reproducing pianos from 1904 until the 1930s and available for free download from the internet. These rolls differ from standard pianola rolls in having additional perforations which define not only which notes are to be played, but how loudly or softly they are to be played and when the sustain and soft pedals are to be used. I edit these in MidiSwing to enhance the playback through my grand piano. Performance practice has changed greatly over the past century and these are a valuable learning resource from that point of view alone.
