It's presets can't be changed via Midi Program Control Messages and Presets don't get reported to the VST interface in the DAW (Sylenth1 does this very well btw).
if I could simply load up a new patch for a track by sending a Midi Program Change MSG it would be such a game changer for performing live. No need to touch the laptop, load a new song in the daw, everything could flow uninterupted while keeping play on, you could keep a Bassdrum going and just lower the volume fader of the channel MUX is on, while it loads a new patch. And since MUX has multiple outs and can host multiple VSTs you don't have to waste any CPU resources having multiple tracks in one Live/Bitwig/Whatever session, you just keep your note data seperate from your VSTs in MUX and change the MUX Modular Patch via a simple touch of a button that triggers a Midi Program Change Message.
<3 please please please make this possible
