[sdiy] Identification of an unknown MIDI CV interface

> p.s. Florian, does this Prodigy MIDI-to-CV interface have the concept of Local Off? I'm trying to imagine what to expect when playing the built-in keyboard at the same time as incoming MIDI is being interpreted.
There is a simple double pole single throw switch, that select between 
the interface and the CV/Gate from the keyboard.

I don't thinkg that there would be a software based Local Off too. I 
received the Prodigy for repair and the interface does not react on any 
MIDI information (at least I don't see any data stream to the DAC). The 
signal between the opto coupler and the processor is there, but nothing 
else. There is a momentary button on the modwheel panel, that switches 
an input of the processor to high; I assumed a "learn button", but none 
of several methods to use it seem to have effect (press, then send note; 
send note while pressed; same with controllers).

I have a very simple EPROM reader somewhere, but I have to check whether 
the old laptop with the corresponding DOS program still will run ;-)


As the owner does not want to spend too much money (and the working time 
will be most of the costs) I will replace the interface with a new one 
assumingly.



And to the others: thanks for all the reactions!

Florian
