OP-XY Master Effect Midi CC?

I’m new to the OP-XY after a lot of time spent on the OP-Z, and I’m trying to figure out what’s possible with this new device regarding external Midi control.

I love the Master track effects (EQ/filter sweep, Saturation, Compressor). My only complaint is that I don’t like having to click into the master->M2/M3/M4 page to adjust them on the fly. Is anyone aware of any Midi CC that can control these effects’ parameters? I’d like to be able to be on the punch-in fx page and still do a filter sweep on the master.

More broadly, any interesting tips or use cases anyone has found with already documented Midi configurations?

Any recommendation on external midi controllers used primarily for midi CC control? (EG Akai MidiMix, Behringer B-Control Rotary BCR2000 USB/MIDI Control)

Lots of information on MIDI CC implementation on OP-XY here:

According to TE list, EQ can be controlled with CC 90 on channels 1-4 :

Curious if anyone has figured out the CC for Knob 4 (Blend) on the EQ page (since CC 90 on Channel 4 doesn’t do anything), as well as Knob 4 (Mix) on the Saturator page. These two would be great to map to a hardware MIDI controller.
