Ah, yeah. I was thinking about the fact that the pedal usually controls aux by default, but I suppose you could change that.
I’ll hopefully have an Ottobit Jr soon anyway, but Guitar2Arp really inspired me. Pedals that do arppegiation like Meris’ Ottobit, the Dwarfcraft Pitchgrinder, and the Molten Voltage G-Quencer for the DigiTech Whammy series are all $250-350! A tap tempo for this patch would be a great alternative!
