Frank,

I've forgotten where I read it, maybe in the promo material for RTs, but I think +/- 10% was mentioned somewhere. So 165 translates to 148 to 183 BPM, approximately. So you are stretching too far on the low end at 106 BPM. It's an audible degradation to my ears. It loses that "sparkle," as it were. Hopefully, that issue will be addressed in future updates, perhaps with more tempo choices for each soloist.

A great ear experiment would be to get Brent picking on a scratch track then rotate the tempo wheel to both extremes nd note where it gets objectionable.
