Hi Andy!

I do think you have an answer to my predicament. You seem to have explained what I am hearing, it does sound like a glitch caused by mismatching of sample rates and wave form frequency.

That number of samples error would easily be audible.

I've been dissapointed for 25 years about this!

How the heck do i get a sampler that samples like 100Khz

Not really in Synclavier money range.

The point of all this is could I make descent wavetables for the Doepfer module.

The example I have heard sounds like a ring modular applied to a tape recorder recording.
