BRILLIANT!!

9.0.2 fixed the issue!

That's my current work-around, as well - but it's less than ideal.

I'm experiencing the same problems with trying to initiate multiple instances of Pianoteq 9 in a new MainStage concert
I'm on Sequoia latest version and using a MacBook Pro M4 Pro chip with 48 GB of RAM .
I am able to still use Pianoteq 8 as a workaround for now for extra instances .
I use Pianoteq 9 as well and I copy it as an alias but I can only use that instance unfortunately .
Hopefully a bug that will be addressed soon

Well, crap. I decided to try updating my backup laptop to Tahoe, but no joy - I can still only open one instance of P9 per concert.

I have sent a message to Modartt; I'll keep y'all posted. I'm really not ready to jump into Tahoe, as I don't believe Cherry Audio nor TAL (my main non-MS plug-ins other than Pianoteq) are good to go yet, but if Modartt says that's the way to go...

Hmmm.... never heard of such a thing, and I've been playing with MS for a decade! Sounds like it would add an extra layer of complexity & add gum to the works...

Modartt will have to help you further, but I thought I'd see if I could replicate the problem and couldn't. Doesn't solve it for you but it might help them help you.
If you have any intermediate plugin hosts, such as Unify... you can host Unify in MS, and then host Pianoteq inside of Unifi (inside of MS). Really good "secret sauce" on its own, and it "tames" many plugins while running in MS. That might work.

I think the concert I opened on this MBP was originally v7 and that wasn't installed on this machine, so... I thought MS always said it could find the plugin and left it at that, but here indeed it opened it with v9. I looked at the actual AU component files, and there were only v8 and v9 there.

Not certain you can, as I need someone who can replicate my issue, but thank you!

Nope - that did not work for me. First instance works as expected. Trying to add a second patch... okay, I hardly ever use patches! What I did was add a new Instrument Channel Strip to a blank patch, then select Pianoteq 9 as my instrument - it tries to open the edit window, but I get a spinning 'clockface of death' every time. If I click out of that, I still have a channel strip with Pianoteq 9, but it won't play any sound.

FWIW: I'm on the last version of Sequoia, latest MS.

Intriguing - mine did _not_ autoreplace my 8 with a 9! The first one I replaced manually worked just like I was used to, but I can't get any succeeding ones to work.

In the past, it didn't use to automagically open the latest version of Pianoteq, it would load the old one. Perhaps... this concert file was pre-v8? Dunno, but it's different.
