These are the electronic schematics of a simple MIDI patchbay
box that allows MIDI mixing and MIDI thru. It is in postscript
format, and I use it for 2 years now without any problem.
It contains 2 pages.
Of course, there is no guaranty with these schematics. If you 
have any questions, feel free to contact me:
