Hi Julian, I just looked at the patches and I hear what you're talking about now. The erratic changes are because it's really hard to get nice smooth tracks by analyzing this kind of signal. With violin samples I got useable results, but the rougher timbre of your viol has a lot of high frequencies that emerge and disappear unpredictably. I think that getting 48 stable tracks out of it is probably a lost cause...even with only 10 it was pretty bad with sigmund~'s default settings.
The only way I could imagine improving things is to use the flag that shows up with each track list to indicate whether it's a new track or a continuation of an old one. With that information, you could try fading in new tracks on free oscillators in the bank to avoid the sudden discontinuity when frequency jumps by a huge amount. Data from a continuing track could safely be sent to the same oscillator. I guess you could also EQ it to get rid of those unpredictable high frequencies - I plotted the spectrogram and the most troublesome ones are above 2500Hz. Of course, that would also put a big damper on the timbre you're interested in... I wish I had a great solution for you, but this is a tough one. Assigning frequencies to specific oscillators in your bank based on track flags really seems like the best bet.
