reeloy thank you for your interest ,

even though i would have preferred some answers rather than questions…
I’ll explain anyway:

I prefer to create long sequences of generative music that I can use especially with the rhythm parts, i really like to use lfo on the notes and their length especially randomly often with the arpeggiator,

so have different lengths for each track increases the possibility of variations on the arrangements. As you say the two sequencers are very similar so i don’t understand why in the same length works and with different length no, (firmware upgrade for MM would be greatly appreciated …)

what I’m trying to do with the OT, I did it with ableton and reaktor so I just wondered if it happens only to me or someone else has found the same limit.
I just have to try to keep on MM 64 steps for all tracks and use the OT per track with master 64.
reeloy you’ve ever tried to use the OT as midi master?
cheers
