Hello,
I've installed NeuronVS without any problem and now I'd like to run it on my Macbook Pro (2012, Catalina installed).
Problem is NeuronVS is VST 2.1 and Reaper and I suppose most of the DAWs are accepting VST 2.4 and upper.
I would like to now if there is any VST HOST running VST 2.1 I could use on my Mac.
Thanks

IIRC, NeuronVS is 32-bit only and you'll need a bridge program to run it on 64-bit only Catalina. I'm not sure you'll run into issues with 2.1 vs 2.4, per se, but it will depend on how the plugin was written. There are a few deprecated calls in 2.4, as well as current calls, that hosts do not implement.

Also, IIRC, I tried running it yonks ago and was not able to do so on Mavericks 10.9. I think it looked for the hardware.

Sorry I can't be more helpful here, but I'm dredging up the vaguest of vague memories.

Hey thanks for taking time to answer. Indeed it seems to be very difficult to run 32-bit only plug-ins on Catalina, maybe I should check in the VM solutions or installing an version of macOS supporting 32-bits applications on an external hard drive.

For VM, you need Snow Leopard Server, which you can still find at archive.org.

I'd check the VST bundle to see if it's PPC, Intel, or universal. I don't recall anymore, but if it's PPC only, you might have to go with an old PowerBook G4.

Anyway, I finally gave up on trying to run it since the graphics were glitchy when I first got it open and I couldn't get any sound from it. It's just one of those programs that has very specific requirements.

Its impossible to run 32-bit code in Catalina, but you should have known this… Mojave would be the one to stick to for quite a while… The advantage of a VM, is that it would run along Catalina and you could try to send Midi/Audio between them… Catalina is dated as well now…

VST Host for Plugin older than 2.4 on MacOS
