Yep, it works! Right now I'm happily comparing your 'Pony' patches (C4) with my own one (Spectrum)...!
Curiously, it only works if I access the 'community' preset library in a certain way. I have to click on the spectrum photo in the home screen so that I go to the editor page, then select browse in the bottom right corner. If I go straight to 'browse' from the home screen, it doesn't work.
In case it's relevant, I'm on Android.
A theory - Spectrum and C4 are actually the same pedal under the hood (like the LA Lady/Aftershock/Kingmaker) but Source Audio have put some firmware in place to lock out Spectrum users from certain features, so that they can offer two pedals at different price points... and I've stumbled on a workaround...?!
