The subject line says it all. With the Exquis app open and a virtual instrument assigned, if I open the instrument editor and want to assign the encoders to a parameter of the instrument to control timbre or whatever, the instrument does not recognize any changes when turning the encoder. The MIDI learn function does not work.
The MIDI learn function works as expected in standalone mode, and encoders can be assigned.
There seems to be no way in the app to control a virtual instrument with Exquis.
Only Factory-supplied sounds via Surge XT seem to have encoder assignment.
