It deserved a topic!
I did it similarly here :
Megabreak of Doom for Analog Rytm
Also mentioned it in that interesting topic. Timestretch
Instead of silence you can add a truncated loop, or several loops with different lengths (in steps)
64+56
64+32+16+8
You can also play loops with lfos, different speeds, placing trigs on all steps.
Velocity Mod can be used with start/end target, Velocity to Vol off.
