Reply to Default Fader Volume

Hello-

I am super new to mappings and I am attempting to mod an existing tsi for my apc40 for traktor pro. I mapped the fader volumes to the faders on the apc, but when I load a new track onto the deck, the default jumps up to max volume. Since I mix mainly with the upfaders I was wondering if there was an easy way to keep the volume all the way down when the track is loaded.

Thanks for your help!
