So I'm trying to edit some drums, I select my drum tracks and create a group with the Quantize Locked setting checked. I select my kick and snare as my Q references, then proceed with using the Audio File -> Detect Transients function, cleaning them both up so there are no errant, bleed transients detected. Then I re-enable my group, enter Flex mode, choosing slicing, and Logic re-scans every track and all my lovely clean transients are gone, back to loads of errant ones. I'm being dim, I'm sure, any help would be very much appreciated.
