DDMF Metaplugin makes ORION effectively blind to VST protocol.
I am using it in 64 bit ORION.
So far I have run VST3, problematic VST2 64 (that I previously had to jBridge from 64 to 64), and also VST2 32. It has an internal bridger of it's own.
Additionally, it has up to 8x oversampling. I just ran a very old EH MiniSynth 32 bit into 8x OS, and the difference was obvious. I say it breathes new life onto your old clsssic VSTs.
I would say this program is a must for running Orion in 2023. They have a demo available.
The only problem I have run into is scanning/bridging 32 bit Focusrite effects. No other issues.
This is the emotion I feel running Metaplugin in Orion
EDIT: I have found a few more oldies that it wont load. AudioOxygen Gemini (1) and a small # of others.
