Hey community

First post into this forum, though i've read some interesting stuff.

I've been struggling with the following on a PC3x.

I got a controller (akai MPK 249) with knobs and more faders and buttons, and my goal is to control the PC3X AUX FX sends via MIDI from there. (Some kind of global FX for all channels despite of the program they have loaded). So far what i managed is:

- Control channel volumes (through cc7), im using 3 channels. All the rest are disabled.
- Control channel send to each AUX (setting the AUX to Override, selecting my custom chain and MOD override set to a controller on the MPK), works good.

All good until here, but i cant get to control the AUX send FX Chain parameters from any CC MIDI (lets say, reverb time or delay feedback, Chorus rate and all these sort of things). I can still control Each channel specific Sliders (A - I) from anywhere. I'm avoiding setup mode, so i can just scroll through programs and have my selection of FX for any of them, and share FX between programs.

Is it possible? if its not, what would you recommend me to do to achieve similar things?
Any help here is appreciated!
