Am I missing something obvious, or am I right in saying that you can only have 1 of each part? i.e. PART_REAL_GUITAR PART_REAL_GUITAR_22 PART_REAL_BASS, etc? I have done a couple of songs where both rhythm and lead need all 24 frets, or I have done 4 separate guitar parts (1 lead, 1 rhythm, 2 combo as bonus lead/rhythm).... This might be due to the original design, but in a future release, how hard would it be to just have "track 1,2,etc", and then assign the instrument part to it?
