In my experience, the Emax does not respond to Sys-Ex fast enough for real-time parameter changes. I had a template for my Remote Zero, that allowed me to make changes, but the reaction time was always too slow, and inconsistent. That being said there are still four real-time parameters that can be assigned to most of the modulation destinations making the filter cutoff/resonance and LFO depth/rate controllable in real time. I have learned to accept this limitation.
