I am trying to make a patch, where I play a .wav-sample forward and if it reached its end then beckward again. I want this loops to be pitchable, so I thought it would be nice to do this with groove~.

But I didn't figure out, to play the loop backwards if its reached its end... Any help? Any workaround?

groove~ plays backwards when the pitch value sent 
to it is negative (e.g. -0.5)

Yeah. But I did not figure out how to detect "end" of the loop best way in MSP-accurate timing...

Great! Thanks. The xsample does ist very fine!

Something like this? It uses a triangle~ with play~ instead of

groove~, but the idea is essentially the same. It outputs a

synchronized bang you can use for many things, including driving

check for reaching the end, I use edge~ for that:

I use the solution proposed by Stefan Tiedje, thank you very much! (I just couldn't use his patch because it doesn't copy and paste right, so I had to wade through the helpfiles a bit.).

If the loop is repeated forwards and backwards it goes out of sync with a clicktrack I have running on another track.

I use a delta~ object at the sync output to detect a change in direction, which triggers a bang via an edge~.

I think the problem is, the the edge~ bangs after the change in direction, which is too late, it has to trigger precisely at the end of the loop.

Do you know any solution to that problem?

I encounter one problem though:

Looping forward and backward with groove~?
