Velocity settings

I've got a patch I'd like to play around with.. a low velocity hit sounds out a low pass filtered sound, a high velocity hit is the energetic full sound. The sensitivity is very high so in order to play the patch I'd have to hit every key at a constant high velocity to get the actual sound I want... where do I change the settings to have absolutely no change to the sound at any velocity? I tried messing around in the oscillators velocity sensitivity settings and brought them down to zero but nothing changed... So I'm messing with the wrong settings. Can someone help me with this issue?
