Set the tempobutton to a variable tempo-range...

[Mellowax]

I would really appreciate this.
I like to use tempochangings in my Sets, especially if I fade into a track played from vinyl by another DJ.
But there it is useless, to have a temporange from 20 up to 999.
It would be perfect if the fader on my MIDI-Controller could change the tempo from 110 up to 140. This would give me much more accuracy, when I only need to change tempo a little.
Get the point?

in midi learn mode many parameters allow you to set a minimum and maximum value, tempo is one of them, see it in the bottom of your screen
