The five cases I've reported before are just the tip of the iceberg - literally every large mix I do in Cakewalk uncovers a bug. I've had clips disappear in take lanes when performing a series of operations on a track with the lanes collapsed. I've had glitches appear at the beginning of renders when they don't appear in playback. I mean, just this minute I opened an old mix just to refresh my memory of some bugs and Cakewalk didn't disappoint - I can't even recall a mix without encountering a crash:
Is FabFilter to be blamed here? This is a recurring theme with Cakewalk - but Ableton, FL Studio, Reaper, etc. seem to not have this issue. If there was a way I could report every bug I encounter, and have faith that it would be taken seriously, perhaps I would report them all. An astute reader might have noticed by now that I have a lot of DAW's - this is because I've started the painful process of weaning myself off of Cakewalk and looking for a replacement, because time has shown that I can't trust it for serious work. I write this as a hail mary attempt at, perhaps, reversing this trend. Hopefully it isn't falling on deaf ears.
My comment about ripple editing and the arranger were meant to imply that a large portion of the bugs you're fixing are for recently introduced features that are at best, nice-to-haves, at worst, unnecessary.
