I am pretty new to live (9) and working myself through the on-line training of MacProVideo.com and learning through tutorials and the manual, but I need advise on this: I need to increase or decrease tempo during live performance with probably 2 footcontrollers. I am already so far that I know how to assign a controller (in this case the cue level of the APC 40) to control the tempo, but I seem to be stuck on how to assign a button to increasing the tempo value with a certain amount (lets say 3 at a time). I found this:
Set up your MIDI controller ---> THIS I managed
Configure 2 buttons on your MIDI controller to send the same Control Change number.
Configure the values sent by the buttons when pressed like this:
Set the value of button A (to decrease the tempo) to '127'.
Set the value of button B (to increase the tempo) to '0'.
Map the buttons to the song tempo:
Enable Live's MIDI mapping mode. Here I find problems.
Click on the global tempo field, press one of the controller buttons (both will be mapped).
Set the Control Type in the Status bar to 'Relative (2's Comp.)'
Exit MIDI mapping mode.
Here on the third line I seem to miss something: 'Set the Control Type in the Status bar to 'Relative (2's Comp.)' I cannot find anywhere on the screen where to do this. See picture.

Also I f someone knows what kind of footcontroller I will need for this? Thanks for your kind attention and help.
