As it says on the title. Would be useful for running standalone without having to use the mouse to change tempo.

Interesting. I'll bear this in mind. First two thoughts:

  1. Would it be necessary to use a Macro knob, or would it be enough to connect Tempo to a MIDI CC?
  2. It could be hard to set tempo precisely with a MIDI CC.

More radical third thought:

  1. Do you really need real-time, continuous control over tempo, or would it be better to create some kind of "set list" where the tempo automatically changes to a pre-defined exact value for each song?

Rethinking it based on your comment, probably assigning a global dedicated CC to tempo would probably be the better option.

As you indicated, CC 7-bit values won't give you enough resolution to allow setting a precise tempo value. I suppose you could allow folks to choose a min and max tempo value and do a linear map of the CC value to it. Folks would just have to be aware that the larger the min/max range is, the less the precision will be. 

As far as #3, I wouldn't need that functionality because I don't perform live, but maybe others might find that useful?

Note: Some many not know this, but when you run Komplete Kontrol software standalone with a Kontrol S-series keyboard, you can press shift and turn whilst pushing the main encoder to change tempo of the internal clock. I was thinking of something similar for Unify.

I feel setting a min/max is absolutely necessary and needs to cover 128 values or MIDI CC will cause tempos like 92.3 and 94.7.  I do use option #3 for playing live.  I set the tempo in Ableton Live with a tempo range and assign buttons on my controller using a fixed MIDI CC to set the desired preset tempo.  But having recently realized I can set the tempo directly in the Unify patch, I am going to start going that route instead.  Will save me not only clicks when playing live, but I sometimes have to do tricky things I need to plan out and practice so the last and next sound don't get messed up due to different BPMs.

I did not know that about the KK.  That's GREAT.  I wonder if it will work like that with Ableton Live's tempo.  I will need to try that out.

Pretty sure it doesn't work that way with Ableton. Sorry.

To change the tempo in KK standalone, I found I had to press/hold the Tempo button (the tempo then displayed in the KK screen) and turn any of the 8 rotary knobs.  You are correct.  Sadly it did not work for Ableton Live.  I know you can tap the Tempo button for Ableton, but there is no long press for manually setting the tempo.
