Are you talking to me? 
if so…
You are right it’s no secret… I’m after a manipulating track tempo multipliers with step events or the effector, but I have asked that even in a separate thread some time ago, I think it would create some exciting rhythmic possibilities (I don’t know if and how it’s doable and whether anyone else could be interested in it) .
The fact that mutes determine the length of a track it’s totally understood, then in another thread I said it was bit of a pain the new mute mechanism, that’s why I proposed that convoluted alternate way here in this thread.
But I got worried :dry: when I misunderstood(?) the intention to replace the length modifier for a shorten a track facility. Having understood the misunderstanding I’m cool 
now.
