Hey guys,
It's been a long time since my last post here on the Teensy forum, but this time I'm back with a new project!
It's a MIDI controller compatible with the Audio Adaptor Board and which can host up to 49 analog controls.
Basically, I used all the remaining pins on the Teensy + Audio Adaptor to implement a shared multiplexer bus which can currently host up to 3x 16 channels multiplexers on 8 pin connectors; there is a dedicate analog pin and inhibit pin for each MUX, while the control bits lines are shared between the MUXes. The 49th is actually just an analog pin hanging there
If you remove the audio adaptor compatibility, that is to say you use all the available pins on a Teensy, you could add up to 9 mutilplexers, that sums up to 145 full analog controls!
You can find the whole project development, from first cardboard prototype made a few months ago up to my exposition at the Maker Faire in Rome, at the following link:

And here's a video of it being played by an amazing kid @ Maker Faire Rome 2014!
Cheers,
Mick
