I do not understand how groove~ works in term of looping and i hope someone can please advise. Please try the follwing: 1) Open the attached patch 2) Read a sample into the buffer 3) Adjust the two numberboxes to be e.g 2000 and 2100 4) Click "loop 1" message and click "1" to start loop at normal speed. This works fine. 5) Then click "loop 0" and the loopend point is ignored and the loop plays to the end. What I want to do is if loop is 0 then I only want to play the selection once and not to the end.
