Hello friends,

I’m running PD with pisound on RB3+ headless controlled via VNC.
I have a patch basically just made out of a cpitchshift object it does sounds like a ring modulator rather than a pitch shift. The same patch on mac sounds great but I wonder why on raspberry's pure data this patch has some issues.

Strangely if I use the freeze command the pitchshift suddely stabilyzes at the correct frequency. If I unfreeze it goes back to slightly sharp with a ring mod tone.

PD set at 48k using JACK and tried all buffer sizes. Very strange as it used to sound fine! perhaps the zexy installer for linux doesn’t have the right version of the z~ object?
Tried to test the microSD speed but it tested ok.

Anything you think I should look into?
