I started to look at the Flex videos he made. I gave up pretty soon, but see that in spite of the unfortunately rather long-winded moaning, there's stuff that can be improved in Logic's Flex engine.
Extremely well-documented vid of more L9 bugs
With all due respect, it looks more like a number of way-too-long clips, made by one who hasn't read the manual, on a un-supported Mac, trying to show how Flex behaves if you want to use Flex for something else than what it probably was primarily intended for.
🙂 He does seem to document bugs as well, but wouldn't a short description of a bug make it more likely that someone from Apple would read and try to recreate this than spreading his feedback over all these videos? I don't know...
I'm basically all for not having to be dependent on manuals, but some of the stuff in this videos seems like perfect examples of situations where spend a little with trying to understand how new, complex feature is
intended to work would make sense.
Nevertheless - I sometimes hear unexpected pops and 'quantizations' when using Flex as well. I'm not totally shocked - after all, this is the first version of Flex, but it does seem like Logic needs a way to force itself to totally ignore non-relevant transient markers that aren't relevant when quantizing.
