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?
