I used the UnO in the past which lead me to purchase a Gordius Big Little Giant controller (same creator), which I think is the most flexible and programmable midi controller.Looked at Uno2. Are you using it? Seems powerful and I like the programming language. Unsure it would solve my issue though.
Ultimately for my use case the Fractal controllers made the most sense.
I wasn't aware of UnO2 until yesterday but it says it's the same engine as TinyBox (again, same creator). I have been aware of that for a while.
Both would allow you to send multiple midi commands on a single button press as @GlennO suggested...
