For many years I’ve used (and loved) the Alesis airFX – a truly revolutionary concept. However, one huge drawback is the lack of midi output.

Thus, you’re tied to the effects in the unit and cannot use it to control other devices. I pointed out this obvious next step to Alesis, to which they replied “we have no plans to continue development of this unit” and it’s been discontinued. Naturally, they won’t share any technical information about it. Well boo hiss!

So, how do we achieve this using the flexible, cheap and wonderful Ardunio board, which I used elsewhere? This page seems a good way forwards and I’ve ordered a couple of cheap sensors from China for  tenner via ebay (look for Arduino Sharp GP2Y0A2YK). Will keep you updated.
