Back and forth of the length of a sample for live playing

Hi guys,

I’m trying to figure out how doing this, what I want is triggering a sample and then being able of playing with its length when it is looped, I think this could be done using varispeed + dub looper and mangling somehow the looper but I’m not with the right key

any tip someone? :slight_smile:

Edit: you can do this with the manual grains unit but the inconvenience is that is poly, could it be possible to have an option in the future for playing with just one grain? @odevices
