I'm new to pure data, and have been trying to construct a granular synthesis patch for use in the prototype module in the program VCVRack. My current goal with this patch is to get pitch shift and time stretch functionality working properly. I'm running into an issue in the form of some buzzing or glitchy sound whenever I play the audio. I made sure to have envelopes on each grain, however it still has that sound when I play a sound. My other guess is it has to do with the metro controlling the snapshot in the player abstract, but I'm not sure of how to properly adjust that.
