I don't like the detune mode, you can't adjust the pitch tracking. Anyway, I should be able to use the fixed harmony for detune, I've done that for years and it has worked flawlessly. Plus there are detune parameters in the mode
And there are several factory presets (including the Micro-pitchshift and Detune slap presets) that uses the fixed harmony mode for detune.
You don't have use that small shifts for the bigger latencys to appear. You can do a step or 2 and it will be there too.
I'm not using the USB, I record thru analog outputs and into a Motu soundcard.
It's really strange that it doesn't happen to you. I used your exact patch and got those double notes in the pitched signal, and I can add a pitch block to any patch, add a little detune and the latency problem will be there. There obviously is a problem since you can see it and hear from what I posted. There most be something you can do?
EDIT: Ok, something is seriously wrong here. I just tried your preset again Adam, and when the track adjust is really high or low, there is alot of loud clicks. Especially with the track adjust low. That has never happened before.
First with track adjust at 6.16, then 0, then 10.
