I'm having a go at making a midi controller for MaxMSP. Here's the CAD.. I might convert it into an audio processor too since it'd be shame not to.. :-). The idea is that nothing is labelled. The LEDS will be different colours so I don't get lost. I can plug a couple of expression pedals in the back too.. Functionally, it works, I'm about to cut the front panel out of aluminium today.. Hope I don't fuck up..
