Hi Guys
I posted photos in 2007 of the schematics (
http://groups.yahoo.com/group/emlsynth/photos/album/524942379/pic/list ) which I received from Dale Blake to make a VP-1 Voltage Processor back in 1985, I've one in my 101 and 500 and worked fine with my ROLAND MPU 101 MIDI to CV CONVERTER, ARP sequencer and Octave Cat allowing the EMLs to track the 1V octaves with no problems.
