Can I ask a question before I waste any money on an upgrade?
With Vsl you can have up tp three (or even four?) keyswitches that are asigned to a certain sampleset. Also, they cannot be placed simultaneously but one after the other.
Is Vst expression cabable of translating the more complex keyswitches including matrix and A/B switches into a single command?
That would be indeed a big timesaver.
