I'm working on my first patch in pd and before I proceed working on it, I woud like to get some input on the sample playback engine I'm using. I'm wondering if I'm losing any sort of sample accuracy that I might obtain by using different objects or methods - I used phasor~ because it seemed easier to pitch. I haven't installed any other libraries other than the base install of pd. please forgive any 'newbieisms' present in the patch. the pseudo-granular implementation is unenveloped and very clicky. what I would like to do is some sort of bpm-locked manipulations (for example: 1/4 speed playback with eight-note sized grains).
thanks,
- Ian
