You are right, i’m sorry I didn’t catch this detail before editing.
Exquis is a controller, and it doesn’t produce sound by itself. But it comes with it’s own application, which embed VST and AU synth plugins, and it comes with a big pack of dedicated Surge XT presets.
If I follow your comment on the ROLI product without embedded equator, then I should remove Exquis from the list. (Done)
Is there a section on the forum which list the MPE controllers?
