Currently, you can indeed already set the QCs tempo via midi message CC#44:
However, message CC#44
is a tap message, meaning that a midi controller needs to send that message multiple times in the desired time interval in order to set the tempo. Which is common practice and mimics the function of the tap tempo foot switch. The given value is irrelevant and will be ignored.
However, I’d love to be able to set the tempo with just one single midi message in cases where I know the tempo of a song.
So for example:
CC #23 Value 0-255
Would set the QCs tempo to the given value in bpm (0-255).
I’m well aware that I could set different tempos for different scenes. But in my personal use case, I’d have to permute all the scenes I already have (clean, crunch, lead, ambient, rhythm, …) with all the desired/known tempos (I’m constantly circling between 108, 114, 117 and 120, for example).
