I've had '20, '21 & '22 Mac BIAB with little or no hiccups in loading or running BIAB. I'm always thrilled & excited by each new version.

'23, however, is so frustrating! Others seem to be having fun, but mine is a nightmare.

Yes, I've hit Rebuild at least a dozen times to no avail. Hasn't helped.

1) It's running verrrry slowly on the same desktop all the others ran smoothly on... 2012 iMac, 24G memory, macOS 10.15.7. Never saw the 'Beachball of Doom' w/ the earlier versions. Now, it's taking 15-20 secs to complete at least half the instructions I give it in '23.

2) Clicking the play button: sometimes the tracks start playing but it's out of sync w/ the moving chord box shading, so by the time they align, 8 or 12 bars in, I have no idea where I actually am in the tune.

3a) RE-GENERATE IS NOT WORKING!! I've lost the ability to add or update various instr tracks. '23 correctly plays any track that I placed there earlier in '20-'22. BUT -- when I need to add an instr now, I cannot get it to play correctly (despite it being a perfect match for the style picked, per genre, time, tempo, style, feel, etc.) -- i) I cannot get any instrument to play on correct pitch, time or feel (even w/ turning on the Fix Key & Chord buttons in the Track edits dialog); ii) it won't just be off-pitch, it's completely out of sync w/ any other track & painful to listen to. In the past, I've simply hit re-generate over & over -- and that would bring a new instr into line w/ the others & sound great together within 2 or 3 re-gens. Now I'm sitting there trying it 9 - 10+ times & it's not even getting close. It remains totally unusable.

3b) This is bad enough in trying to add a new instr track, but when having to update the re-generate on a long established track (by adding a few bars or otherwise updating the structure, etc.), I now LOSE THAT long-perfect track. Not just that one performance pass -- now that instrument itself will no longer work & creates the same problem as the new instruments. And I can't get it back, if I've saved something else along the way.

3c) I've been forced to completely re-arrange 3 or 4 songs now simply b/c of BIAB '23 blowing up on me! UNACCEPTABLE!

4) Upon opening a track I'd labored on, installing tricky bar lyrics into while in '22, Voila! Opening it in '23, all the lyrics are gone. Just not there.

5) Sporadic dropping out of saved instruments when opening a file in '23. I rarely use Utility tracks & will place instr. on the main tracks. So, I'll have a certain well-considered & chosen guitar or something else on some track, fully saved. I open that song file in '23 & it's GONE. Only the white empty Guitar, Strings, Melody, etc. track. I've always relied on BIAB's ability to save, & am paying for it as I have no recall as to which of the 10,000 RTs I had in that spot.

I sincerely do NOT like to complain & I've been totally blissed out by BIAB '20-'22. But I'm finding '23 nearly totally unusable. I haven't even had a moment since installing it to eagerly explore all the new aspects of '23, as I'm still battling all the destruction of what I've had in the earlier versions.

Please help. I'm at my wit's end...
Much appreciated!
