need help recreating a sound

[Ascension Dream]

Okay, so...Im not too great with running my keyboard, but the other night, I had something going that I really really liked. The next day, it was impossible to for me to recreate what I was doing.

I somehow had all 16 controls on my e-mu xboard25 working as volume knobs while I was using the m-tron emulator in logic express.

if anybody could help me figure out how to make the knobs all work for volume again..that would be amazing.

Im normally a guitarist, but am trying to learn keys.
