8x8 Midi Patchbay
This is a project that came about
because I was in desparate need of a midi patchbay, but at the
time they were few and far between, (this was in the early '90s)
and when I finally found one, they wanted $400 for it!!, I couldn't
afford that. then one day I was reading one of my Amiga computer
(remember them?) magazines, and it had an artical on how to build
your own midi interface, as I was looking at the schematic, I
suddenly realized that I could modify it to make my own patchbay.
I started out with a 3 in 4 out, then went to a 4 in 8 out (which
a friend of mine is still using) and finally to an 8 in 8 out,
which I am still using. I put the 1&8 inputs on the front,
and the rest are on the back, each knob on the front panel represents
an input, that can be sent to any of the 8 outputs, the LED gives
visual indication of which inputs are active.
