While I don't have a Fractal....yet, here's a way to use a Line 6 FBV3 with full color LED and MIDI functionality using an Arduino and Raspberry Pi. You can also use a Shortboard MkII if you'd like. It's fairly straightforward to put together with minimal parts and based off of prior Vlotech / Axeline projects. Those of you with Fractals (I'm assuming most everyone here), maybe you would be interested?
