I have some existing Mackie devices plugged in to my PC (C12W11). I can no longer see them in studio set up. Your MIDI remote manager does NOT work with hundreds of devices including the most up to date cutting edge keyboards such as my Arturia 88 MkII, and also custom devices made by small manufacturers and legacy devices. Your list of supported keyboard is tiny in comparison to the number of keyboards on the market.
I can unerstand you wanting ot improve the current MIDI device set up to a more friendly GUI, but PLEASE to not declare war on legacy devices! I have heard rumours you intend to ditch the old Mackie and legacy set ups. PLEASE, do NOT do this!
