Vesta Kozo MDI-1 Midi <-> CV Interface

I actually had this for a short while in 2003, but decided it's not suitable for me, and hence sold it in 2004.

The Vesta Kozo MDI-1 is a strange Midi / CV Interface, made in Japan, in 1985.
There are a few unique things it can do.

CV is 1V/Oct and it has this odd Trigger IN input (converts Trigger to MIDI?!)...

Originally designed to use with Vesta's DIG-420 Sampler/Delay but also can work for any 1V/Oct synths.

Although I don't have this anymore, but I did take some photos and have some info and files on it. Again, there is not much info if you google on the MDI-1, so I am keeping this page and files here for anyone who needs info or who's just picked up one of these.
