Keyboard Matrix Interface For EK-3 | |
Article from Polyphony, November 1977 |
You'll notice that the board can handle up to 49 keys (4-octave) but of course works just as well with 3 octaves (which is what I'm using it with now, till I find a good 4-octave kybd). In fact, by extending the pattern, you can use it for 5 octaves. Also note that all keyboard connections are brought out to a dual readout connector. By sawing a 16-pin DIP socket in half and soldering the two halves into the connector holes on the component side of my board, and then soldering bits of excess resistor lead into the connector holes on the EK-3, the two boards just plug together, no point wiring involved!
