Hello all,

I have Machinedrum with OS 1.19c and have troubles with lock 
parameters on midi tracks : when I set a lock on a step, the next two 
or three notes keep using those parameter settings (they do not come 
back to initial state). This behaviour stops a few notes after. I can 
only correct this by locking those notes, which can be a very memory-
consumming process. Has anybody ever experienced the same bug ?

Thanks,
mike
