the manual mentions that the new Note Expression feature works well with VST3 controllers as well.
However, the only “compatible” device for note expression is currently the HALion Sonic SE.
Unfortunately Steinberg VST 3 synths, like Prologue, Mystic are not listed here. It would be a great chance for Steinberg to make these (otherwise great) instrument much more popular than they are now to make them Note Expression compatible.
So when can we expect VST3 Note Expression support for the other VST3 products?
