NDSP Quad Cortex

The SLO 100 PCOM amp is the best QC amp model. Fight me 😝🤘
There's no doubt that the SLO 100 plugin model is 100% awesome. My favourite high-gain amp models from NDSP are the aforementioned SLO, Plini Rhythm and Lead, Nolly Rhythm and the QC Kraken. The Rabea X Kraken is great too, but I slightly prefer the QC model. At the moment, I spend most of my time on Plini Lead, but that changes constantly.

My all-time favorite has been the Nameless but recently I'm digging amp3 (the black one) from the Misha plugin. It's a Friedman BE in the down position, works fantastic for classic to hard-rock, and a Bogner in the up position which brings the pain.
 
Just picked up the QC today and wonder if it's possible to use the Mission Engineering SP1-L6H-BK expression pedal, that I used with my Helix Rack. Would like to use the pedal on the QC like I used to do on the Helix; volume pedal and switch to wah or whammy with the toe switch. I've read somewhere in my search for an answer, that the L6 pedals are not compatible with the QC. What is the difference in hardware between the SP1-ND-GY and the SP1-L6H-BK? Is it the wiring or the potentiometer?

Here's my DIY L6H expression pedal, transplanted in a Vox wah. Want to mod it again for the QC if necessary. The ME pedals are way too heavy and overpriced.

EDIT #1: toe switch works as expected on EXP2. The pedal sweep doesn't do shit when connected to EXP1. Doesn't matter if I use mono or TRS cable. It doesn't register any movement. Need to replace the resistor and/or potentiometer.
EDIT #2: found this info from ME: The Mission EP1-L6 Pedals are designed explicitly to support Line 6 devices. They are wired Tip and Sleeve as opposed to Tip, Ring and Sleeve in most other expression pedals. The Line 6 expression interface is different to most others in this regard. The EP1-L6 requires only a regular mono guitar cable in place of the stereo TRS cables required by other pedals. The EP1-L6 uses a 10k linear potentiometer for accurate tracking on the Line 6 processors. Since the EP1-L6 is wired TS, it is not polarity sensitive and so no polarity switch option is available.
Conclusion the potentiometer I have in my pedals (Dunlop ECB078 10K lineair) is the right one. I need to rewire the pedal. Let's heat up the soldering iron!!!

Any QC Mini owners encounter this?

the pre-roll being greyed out in the LooperX on the quad cortex mini as well as the Midi clock and quantize.
Is there something I am missing?

Also when I unmute the metronome, there is no way to change the volume of the metronome.
