Most of the things I think are bugs are just me doing something wrong, but I'll risk it again.
I've just finished making an eight switch foot pedal out on an old USB keyboard and so far it is working pretty well. Two of the characters I chose for switches are '.' and ',' however and they don't seem to be liked by the keyboard mapping facility in SooperLooper. If I go into .sooperlooper and edit the XML things work just fine so I'm not really worried about it, but I just thought I'd mention it in case it is a bug of some description.
