You should use [waveform~] to get your loop start & end points ….
Then store them in a [float] (right inlet) one [float] for start & the other one for the end points! & then just bang to the left inlet of your [float]s to your groove~
Hope it helps !
if you take a look at the groove~ help..
i copied the delta~ -> … -> edge connection.
so everytime the loop is played through edge sends a bang to stop -> groove~.
so even if loop is turned on the sample will only play once.
but now the problem is i cant play the sample reversed.
iam sure its because of the (< =~0.) object in between delta and edge...
i need to change the value of this.. but i dont know how…
