Hmmm, if only I could use maths to shrink the loop size as [sig~] speed falls, and vice-versa. Here’s a small excerpt of the patch, highlighting the problem:

But I think the [expr] calculation you are asking for is frequency to milliseconds, which is
1000 / $f1.

I’d like to stick with [groove~] if possible; but no matter how i implement the [expr $f2/$f1] function, playback is always relative to sigspeed, ie if sigspeed=0.5, loop length is half of that when sigspeed is 1. This is really frustrating me. Any further suggestions?

That equation up there will make it so the overall loop time remains constant, and the loop points move accordingly.

I think that’s what you are asking for?

Yes, this does perform the same function; but i had got bogged down in trying to use [expr] cos i thought that’s where the answer lay – well spotted, and thanks to both for the solutions – btw: I’m compiling a ‘live granulation’ tutorial for someone on youtube, to expand on the excellent ‘Baz Tutorials’, so i’ll post a link when its done, tomorrow
Good wishes
Brendan
