in various posts here in the forum, people discuss foot switch options for the Qu series. Ideas range from connecting a MIDI floor board via a computer to some standalone ethernet floor board DYI project etc.
What would be extremely cool for MIDI floor boards, but also for all kinds of other stuff: The soft keys should be triggerable via MIDI messages.
This would be great because then the actual mapping from, e.g., a MIDI foot switch to commands could be done in the Qu16. Furthermore, it’s quite straightforward for the user.
