Serato Pitch'n Time -artifacts?

[Zep Dude]

Hi, I just tried the demo version on a 4 bar multitrack drum phrase (18 tracks of live drums). I just needed to stretch a phrase by maybe 2% -quite a minor task. Unfortunately, it created a "whoop" sound every time the snare hit -yeah "whoop" as in 3 Stooges (my engineer and I tried to disable the 3 Stooges setting in preferences but it wasn't there). Doing the same thing with Pro Tools built in TCE was fine.

Seriously, we did find something in the Serato Prefs about optimizing for transients and tried the time stretch both ways but with the same result. We also tried the stretch directly with the TCE tool as well as the Audiosuite plug in but always the same result.

If this thing is supposed to be able to stretch entire mixes flawlessly why can't it stretch some multitrack drums as well as the built in DigiDesign time stretcher? Geez glad I didn't shell out $800 for this!

Anyone have any comments or suggestions for getting this to work?

I was told by Wave Mechanics that both speed and pitch n time are designed for stretching, etc stereo mixes-- and not for individual tracks. I don't know why though.

That sounds about right. I messed with this thing a little further -tried setting multimode for phase coherency and it really changes the sound from the original. Like I said, the Digi built in time compression did a pretty good job at the same task.

P&T version 2 is the one for multi mic drum tracks etc.... Make sure thats the one you are using...

Jules, have you had success with this? I've got the v2.01 demo and no matter how I set it it changes the sound quite noticably. What procedure/settings do you use for multitrack drums?
