I found this guide on how to build a fully functioning MIDI keyboard with a low budget and a lot of brainpower.

Clicky

Very helpful for anyone who needs to assign multiple devices to different tracks, but who would prefer not to overspend.

It requires you to open up a "toy" keyboard and create a whole note "matrix" but if you understand it and do it right, and install firmware onto it sucessfully, you should be able to send midi data through USB and therefore get it to work with Reason.

I can't imagine how unreliable this would be and what sort of delay it produces, but it's still handy to have some extra hardware lying around. I'm using my old Casio, which I've dissected, and I'm giving it a sort of Mozart-era harpsichord inverted design, with the Sharp notes White and the Natural notes Black.



I'll post back here and tell you how I get along with this. I'm not so sure if this WILL work with the keyboard I'm using atm but it should.
