I have been playing with K2.1 since the update this morning. I became very excited at the much improved pianos that were downloaded. I was then quite frustrated when the PMI Hybrid pianos, which I have come to love, now do not seem to work correctly. The sustain pedal seems to now only hold "sustain resonance" and not the notes themselves (except for a couple of exceptions). I would appreciate guidance if I am missing something (which is very possible do to the fog I am experiencing after a day with the computer).
