I’ve set up a Streamdeck+, so that I can adjust levels on the device, and see levels coming in, control fx, tap tempo etc.
Here’s a little video of my setup in case it helps anyone else: https://youtu.be/UarLho8fpkI
What I quite like, is that you can duplicate MIDI controls across different pages on StreamDeck, and it all stays in sync through the StreamDeck plugin.
n.b. Some of this is probably easier if you have the official Cantabile StreamDeck plugin and/or use proper bi-directional MIDI bindings (both require the ‘Performer’ version, which I don’t have yet!).
TLDR: you need to use a virtual MIDI port program (like loopMIDI) to route MIDI between Cantabile and StreamDeck, and use the ‘MIDI’ plugin in StreamDeck - the Mackie controls in this are the ones to use for MCU. Inspect The_Elf’s template here to get the bindings you need.
