Exactly how I’m feeling. I know I probably need the bigger one for more switch functionality, but my brain is desiring the mini so bad.

I got my 4 scenes, that’s about all I need tbh

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.

I suspect you have one parameter set in such a way that that the clock and quantize are mutually exclusive. I'm away from my QC at the moment but I'll try to have a look tonight and see if anything jumps out. In the meantime, you could always try emailing: support@neuraldsp.com

I found out the quantization has to be turned on for pre-roll to work. Kind of surprising that I would need to quantize the loop just to get a count in.

I think the idea is that pre-roll supports the quantization. If the tempo isn’t defined, why bother with a pre-roll at all?

I want tempo, but isn't quantization computer adjusted tempo? I want to hear the metronome and use it to lock to create my loop. The pre-roll is just to get ready before everything starts.

You're probably making more sense than I am here. Let me actually mess with my QC a bit before I write anything too stupid.

no worries. I am pretty new to looping, so maybe my expectations are out of wack.

I've been banging my head against this specific wall, on and off, for about 30 years; and my expectations are still out of wack.

Did some testing and got it working. First with some croc clips for easy swapping of polarity:

Found the best working wiring:

Solder the wires:

Close the box:

I replaced the tinfoil bottom plate on the wah, with one made of mdf (also on the Mission) as it won't allow to stay put with velcro.
Use this settings on the QC to get it switch between the wah and gain block:


I'm thinking about replacing the momentary for a latching switch. I just found one here, while I was looking for other things in a drawer. For EXP2 I need to put the QC in latching emulation now.
The polarity of the potentiometer is not as the QC expects it and I need to change the min and max whenever I want to use EXP1. (Swapping the tip and ring wires didn't work as the smooth sweep became an on/off switch.) However it works and if you want to convert a wah or your Mission Engineering Line6 pedal, you sure can. I rather have this Vox wah; same performance as the ME (Line6) pedal but half the weight. The ME pedal is twice as heavy (yeah, yeah, "built like a tank blah blah" ) and up for sale.
