Reply to Help Mapping Gain Knobs to Filter on/off

Hi Guys

Its been bugging me for some time... I dont know how to map my S4. Im trying to get the push button on the gain knobs for each channel to act as a switch to turn on/off the filters. I used to mix this way with my old kit and miss being able to filter out individual beats at the push of a button.

Can anyone spare the time to talk me through the mapping process, since it seems to be a lot different to my previous set up.

Cheers Paul
