hi
this bug has plagued the midi machines in the past and its very frustrating *howewver* it was addressed two updates ago and i havnt been able to get it to do this since i upgraded to UW. (the unlocked step following a locked one would play the same note as the locked one, subsequent steps would play the default note as indicated.) i cannot test what you say @ the moment im at work
i did notice a very similar problem in midi machines with the note LENGTH.. same symptoms you describe.. 1.29D perhaps you could double check that for me?
