Next version of MacOS probably doesn't support Sound Manager

[analogika]

BTW: the fact that Macs released after a major system upgrade generally cannot be downgraded to an earlier version without hacking and loss of functionality, if at all, has been basic professional user knowledge for AT LEAST twenty-five years.

People often keep an older backup machine around or quickly shop for another used machine when catastrophe besets them, rather than buying new.

Normal.

I can’t upgrade for a while yet, anyway: most of my audio unit plug-ins won’t be compatible until around Christmas, at the earliest — as every year.

How do I know if all my plugins are 64bit? I checked with various articles and they said that the info of the plugin will have "32 bit" in the description...
All my plugins DO NOT show "32bit" notes... So I guess they are all 64bit?

btw: I just bought a 512GB external SSD (T5) which will become a full clone of my current Mac SSD - so I'll test everything and ... IF ... everything works just fine, I'll do the upgrade to Catalina, ...

That's what I will do, but I'm going for the Samsung X5 because I fear the USB3 T5 will be too slow for my liking...
I don't need to keep 32-bit support for my music stuff, but I do need it for work for another year or so, after which I won't need a client to connect to my work's database, everything will be browser based.
Bit off topic, but would you mind sharing your experience with the T5 whether booting and working from it is fast enough, compared to the internal SSD in your Mac ?

Actually, as it turns out, none of us are 100% correct...

Skip down to the “Hedging Your Bets” section:

APFS supports the ability to create a new volume on an existing disk. This allows you to install Catalina on your Mac within a new volume, without overwriting your existing installation of Mojave. You can subsequently boot from either system using Startup Disk in System Preferences. Note that having multiple versions of macOS on your system will use up lots of extra space and that each will need to be kept updated to the latest OS version separately

Not sure what they mean by lots of extra space.. the system folder only takes up about 6.5 gigs. I wouldn't exactly call that huge.

Correct for the operating system itself, but you also have to install the software you want to use in Catalina again, which takes additional storage space if you don't integrate the "old" volume into Catalina and point to the programs folder on this "old" volume. Same for user data ifn this is located on the "old" volume.

Not sure what you mean by point the programs folder on the old volume. Mac programs do not have a registry like windows does and in most cases can run from any location. There are a few that have license servers that might have to be re-authorized, but for the most part you wouldn't have to do anything more than boot up with the version of the OS you want to use.

If you really want to keep things separate than yes you would need to duplicate your Applications Folder, but terabyte drives are cheap.

That is the EXACT opposite of what I was describing.

I wrote about NEW machines no longer running OLDER OS versions, making them unusable for people whose essential software hasn’t been updated for the new OS yet.

Installing the newer OS on what amounts to a separate logical partition will also install an entirely new Applications folder with the new versions, and require reinstalling all authorisations and third-party software over again.

Mac OS Catalina has now been released and the current Nord Sound Manager v7.46 is not 64 bit compliant.
