Everything works great with Catalina, provided you don’t need to run 32bit apps as Catalina is a 64bit only OS.
As mentioned in my post further up the thread - also be aware that some hardware needs specific drivers (eg my eMagic Unitor MIDI interface) and if it's fairly old technology, like my Unitor, there may NOT be a 64-bit driver available. But my Unitor is working perfectly, and so upgrading to Catalina - for me, at least - would require not just scrapping several plugins and apps, but also some hardware.
No Will Farrell fans here?
i play Jazz Flute through my AXE FX III Rig...It's good enough for wine mixers.......
All the warnings I'm getting from Catalina are about plugins so I'm with you there.I fear Big Sur might have dire consequences for many music making apps....hope i am wrong.
I had used Big Sur Beta's, 1&2 were just fine. beta 3&4 both had plugins not work, not even the manufacturer show up in Logics plugin manager despite being in the Components folder and working with Catalina and the first 2 betas. One group of plugs all work but one from another manufacturer. No solution, not sure as those plugs have had recent updates. There’s no beta 5 yet, but first time I reverted back to Catalina. As always, backup backup backup.
Ax8 edit worked, no problema.
I've been delaying upgrading to Catalina for just this reason. Which brands of plugins are you having problems with?
