Just received my MOD Dwarf Beta unit today (in Ontario, Canada). Plugged it in, upgraded the firmware, and plugged my home-brew control chain pedal in and it works - even my hacked together tap-tempo (although I have some firmware cleanup to do still)!
I’ve noticed a couple of weird things so far but I’ll post them separately as bugs. All-in-all it’s a remarkable little unit in such a small package! Congratulations on the design and implementation! I know how hard it is to put that much functionality in such a small package and user interface. I’m very impressed!
