Update on Midi-CV interface

[Isac Georg Jensen]

I just wanted to thank all of you for giving some input, regarding my
MIDI-CV converter.

I couldn't get MIDI signals thru to the mikro-processor, but this
problem have been solved. The initial design had a 'standard' CNY-17
optocoupler, seperating the microprocessor and the midi cable.
Inspection of the data sheet told me that the CNY-17 would be fast
enough, to handle midi-signals. But I only received garbled messages.
Someone (sorry can't remember who) suggested that I used a 6N138
optocupler (from Hewlett Packard), rise time is some nano seconds. With
this change, I am able to receive the midi-signals, but I still can't
figure why the CNY-17 doesn't work ! Well, back to work, I still have to
implement the code to handle the signals.

Thanks, alot
