Thanks Andrea - happy to get those tools, but it doesn't seem any better than tapin/out in this particular patch.

I'm about to try 2 delays with phasor to swap between the two, and fiddling with delay times and fft sizes, overlapping sizes....but maybe that's a dead end?

Hi Lee have you checked out our "good buddy Sam" at Delicious MaxMSP on youtube? He has a good collection of both fun and didactic tutorials, including delay-based pitch variation; I'm sure you'll find something you can hack.

Yes....but it's not really delay-based pitch shifting I'm trying to do, it's combining a delay with pitch-shiftiing on a feedback loop that I'm trying to do....the delay itself is (and I think needs to stay) static...

I think you're running into the reality of digital audio. Each individual sample has no pitch; pitch is an emergent property of a group of samples. You can't really shift the pitch until you've collected a group of samples.

I made patch called harm-gran~ in the CNMAT downloads that does pitch shifting on relatively short windows. But there are still audible artifacts. gizmo~/pfft~ also imposes it's own delay. In the time domain, there really is no pitch shift without some time shift.

Well now you see, this is why I love max/msp and it's community: helpful, unpatronizing explanations.....we all learn, and move on. Thanks doc!
