Reply to Slice and Echo Buttons

Even though they are certainly fun to play with, I am trying to change the dedicated slice and echo buttons on the 3_5_1 TSI. Perhaps to a dedicated beatmasher and some sort of buildup/white noise.

Does anyone have an updated tsi w/ the dedicated slice and echo changed? Or can someone tell me where in the midi map those two are? I am not sure if they have modifiers on them.

Thanks
