I'd just like to point out that this is my first post to this forum, first and foremost!
I've used Flex Time many times in the past but I now receive the following bug, and I cannot figure out the source or how it even started. I have a recording of a drumset with 10 audio tracks, grouped together with phase-locked editing mode engaged. The song itself is about 9 minutes long. I have comped and mixed the drums. I am now editing the timing via Flex Mode(Slicing) and every time I move a flex marker, Logic gives me the pinwheel and it loads for 10 seconds, which is excruciatingly slow for the amount of edits I have to do; in fact at this rate it'll be hours of merely moving flex markers around! This never used to have to "load" every time I move a marker, so there's definitely something weird happening.
I've tried removing all plugins for the tracks, freeze mode is off, all the drum regions are flattened and merged, I've tried splitting the region into a short segment and adjusting the flex markers to no avail, I've tried creating a brand new project and importing the drum tracks and their content(via media browser), and I've even tried recording the output of just the "kick in" track, bussed to a new audio track and using flex time on that, to no avail.
I am using a 2013 Mac Pro, 6 core, 256 SSD drive.
The projects are stored on a 10,800rpm G-Drive harddrive.
OSX version 10.10.5. Logic version 10.2.2.
Thanks for any help.
