Hi Bachus,
controlling VST with an external synth is an easy task but all deppends which synth.
For now the PA series have the best MIDI routing that exist on any existing machine,
including their workstations too, better then M3 or Motif or anything. Its very easy.
With the Audya no, you cant cuz Ketrons MIDI routing sux, its the worst, you'll get stuck
and your system will freeze in the first 5 minutes and not even that, first of all the synth
dont even have some options for external controlling, its like the synths 15 years ago.
Last, yes you can convert styles from anywhere but then you'll need to work on them
on Audya and fix them to your liking.
