i developed this little patch intended for de/incrementing the tempo of Live with Monome button presses. thought it might be useful to some. it s applicable to other sequencers and controllers.
the patch gets midi clock from live, de/increments the tempo in 1 BPM steps and sends out the new tempo value as midi CC to live. this way live remains the master clock. i prefer this to making max the master as i have 2 more sequencers slaved to live.
there s rounding errors of around 0.15 BPM because of the necessary scaling to 0-127 and inaccuracy of the incoming MIDI clock and sync~ object. that s good enough for me though.
