I'm looking for "good" MIDI files (for example of Bach pieces) i.e. :
* really played by a real organist, no MIDI written with a software

* one channel per keyboard (1 channel for Pedale, 1 channel for GrandOrgue, 1 for Positif, etc.)
* and above all, NOT stuck to a strict BPM from beginning to end, that makes the interpretation "robotic" (because there is no slowdown, no acceleration, etc.)
Has someone such MIDI files ?
Or has someone interpretation skills that allows to record MIDI files ? (I'm not good enough to be able to record well played difficult Bach pieces

Thanks a lot in advance!
