DAD offers to make custom firmwares so there is no need to be a developer to be able to use. Several firmwares are already available, just send to PC, dedicated to the pedals Strymon, Eventide or Line 6 ...
Note that you can choose the color of the box following a broad panel. The pedal itself is compact but solid, very well built. No extra cost you can have a 7-pin MIDI input power via the MIDI cable.
The DAD team responds very quickly to emails, it's nice.
According to me, the only downside for LEDs, which are VERY powerful even blinding.
