yes, I find the main problem is it's transposing when there is no need to, like during rhythm it plays the same rhythm an octave up or down that throws you off, also on beat 3-4 of a chord.
It's understandable to transpose solo playing to give a lot more playing over different chords.
The only way to get better user tracks and less transposing is more playing not just the standard template that pg supply, like 1min 10min is nothing when you compare it to the amount in real tracks.
I think once they get all the problems ironed out you might get 3rd party user tracks as they will be competitive with real tracks.
