I did a quick retest. I used a 4-bar pattern, this time C->G->Am->F (Bossa tribute to Let It Be), Copy From.. To.. number of x to repeat copy = 10 and it worked fine. I re-entered my initial chord progression, C->Fm6->Bb7 ,Bdim->C, copied it number of x to repeat copy = 10, and it crashed during Regeneration.

Did I find the chord progression that is to never be played?
