I’m still loving mine and have got a tap switch to change presets. I’d heard it is fussy about power supplies but my gig last night was something else - the venue’s power did not agree with it at all,  even with any of my power supplies. It was so noisy I had to take it off my board. My boss and ebs pedals were unaffected. My only other gripe is that it’s easy to accidentally change preset when you press the main switch, would be great if the preset button deactivated when you connect an external tap switch.

Isn’t there a way to reassign what function the main footswitch does?

Yes, you can scroll through presets by holding the main foot switch but it’s clunky and your foot covers the preset lights so it’s guesswork which one you’re on.

What I meant was that if you plug in an external footswitch, then you can reassign the main footswitch so it doesn’t cause the problem you mentioned above.

Ah ok. I’ll have to take another look at the manual, I don’t recall seeing anything about that

Basically just don’t put the main footswitch into preset selection mode (long press); just leave it as an engage/bypass switch.

Thanks and sorry for the confusion but that’s how I’ve got it set up. The issue is that it’s easy to hit the tiny preset button (next to the four red/green LEDs) when using the main foot switch as an engage/bypass switch. I just need to work on my foot technique!

Ah, I see.

Well, its found a place on my board.  Still getting to grips with it, but it's a VERY cool sounding unit, easy to adjust the parameters for the most part, and all the sounds it makes are actually useable, rather than something to just muck about with. Took a good bit of messing about to get it working well in my QC chain.  Naturally, it doesn't track nearly as well as I'd hoped.  The hammer-ons and pull-offs not re-triggering in Ian's videos was what I was really hoping would work, and it does for the most part below the 7th fret or so, but any further up on all strings it retriggers, which is frustrating, and a tad confusing really as I'm not sure I understand why, for example, G2 on the A string will hammer nicely from F, but retriggers on the D (10th vs 5th fret).  I'm sure using old flats help a ton, EQ curves and compression on the QC help tame the harmonics  and smooth things out from the rounds but its still not brilliant.  Still, it handles ghost notes well and there isn't a ton of latency, as long as its in 4 string mode.

 

The first and last preset are my faves, the last being quite similar to one of my favourite patches I had on the Chunk synth.

 

 

Having spent a week with this, the retriggering with hammer-ons in certain settings is just about the only negative I have.  It sounds brilliant, and now I'm learning how it wants to be played, it's tracking very, very well.  Having everything adjustable by twisting knobs is just wonderful, can't be a coincidence that the only two synth pedals I've ever got on with have not involved PCs or apps.  Fat fingers will struggle a tad though, i can see some finding it hard to adjust knobs without knocking others, which would be especially frustrating when adjusting saved presets.

 

Did I read somewhere that there is a way of setting the pedal to work as a filter without any of the synth voices in the mix IE a filter affecting Dry signal only? It's not something I've spent long looking for but it isn't immediately obvious to me how.
