Ensoniq Mirage Mods

[SynthularModulus]

I just picked up an Ensoniq Mirage, and would like to explore modifying it. Anyone out there modded a mirage? In particular, I am thinking about Cutoff and Resonance controls of the CEM 3328 chips, which should be relatively straight forward to do, but I am curious if folks have tried this or any other mods/bends on a mirage.
