Other than going into settings, does anyone know if in Traktor, or on Traktor controllers whether or not there is a quick one button push to get a wide tempo mode?
You can map a key/button to increasing/decreasing the tempo range using the controller manager via the controller's or keyboard's mapping file (tsi).
What do you mean by WIDE?
Tempo range setting?
^^ That must be it. I am stupid today.
