Hi
For audio plugins it's possible to insert both DX-type and VST type.
MFX plugins for midi is DX technology - so why not VST type there too?
Thinking of large VST bundles like piz midi plugins.
It also has a ini-file to set how to identify itself - as synth, so so audio ins/outs or not etc.
I use today inside Patchwork from Bluecat, but would be handy for general use without serializing many tracks.
Thanks for any support on this.
