How to MIDI control the BPM in decimal places?

I have set up on fader for the BPM (set) and two buttons for inc and dec the value by 1.

I want to set a new crossfader to do the fine beatmatching. +/- 64 in midi values. +/- 50 cents for setting the 2 decimal values next to the BPM.

e.g. 175 set by the buttons and then use the ‘fine’ crossfader to go175.23 or 174.68

Renoise does accept bpm with 2 decimal place accuracy and I would like to control this so I can DJ my production on the fly while listening to internet radio.

Is there a way to do that?
