hardoff, thanks for the response! and sorry mine comes so late. checking the samples, they are all def. 44.1khz and its looking like the click removal may be the issue-the rate problem is more apparent on samples with relatively higher gain/waveforms with more clipping.
out of curiosity though, what's your process for sampling? ive just essentially been cutting samples w/recycle & exporting them. maybe the issue lies somewhere in that?

No, not really of course... You should check if the "compute audio" checkbox in the pd main console is turned on. If so, check the output in the console. Maybe you have some objects missing... Also make sure you're audio is properly configured, by opening the test audio/midi patch you can quickly check this.
