Appendix A

Controlling the Model 50

The Model 50 Central Controller uses MIDI

system-exclusive messages to control all

functions. The Model 51 Control Console

is programmed to generate a subset of

what the Model 50 is capable of doing.

By using standard MIDI messages, the

Model 50 can be used for a wide range

of special applications. Any device that

can be programmed to send system-

exclusive MIDI messages can be used

to control the Model 50.

Note that the 5-pin connector on the

Model 50s back panel is wired somewhat

differently from a standard MIDI input.

While pins 4 and 5 meet the MIDI stan-

dard, the three remaining pins are imple-

mented for use by the Model 51. Pin 1

supplies +15Vdc power, pin 2 is shield

(ground), and pin 3 is communications

audio input.

If youre connecting your own controller,

such as a computers MIDI interface, you

might be concerned about the DC power

on pin 1. Because the MIDI standard

doesnt use this pin, it is highly unlikely

that it will be connected inside your con-

troller, so theres little chance of the DC

causing damage. To be safe, you can use

a MIDI cable with only two or three wires

implemented.

The following pages provide a detailed list

of all Model 50 system-exclusive MIDI

messages.
