Looping forward and backward with groove~?

020200's icon

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)

Feed groove~ a triangle wave.

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

Hi

I'm looking for information on how to integrate GPS devices with
MAX-MSP -
are there converters / patches which exist to make the linkage? Is
there available
documentation on this integration?

Any help would be most welcome!

Cheers

Marc

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
groove~.
If you want to loop over small portions of a buffer, that will require
some additional calculation, but setting the lo and hi points of the
triangle~ should provide that.
