Aphex 5200 RC Interface - Manual (Page 7)

NOTE: We will refer to the Reference Data at the end of this chapter for command codes used
by the 1788A.
When programming each control, use the following setup:
1. Single-byte transmit
2. Faders: string; Buttons: string toggle
3. Fader Limits: 26 to 65
4. Faders: use “pr” in the value byte. This is the PC1600’s code for grabbing the fader’s value.
5. For this demonstration, we’re using command code 00 for Input Gain and 07 for Mute. We’re
declaring the 1788A is set for Channel 1, Device 1, Net 1.
Now program in the following strings:
Connections
Connect a professional MIDI cable from the PC 1600x’s MIDI OUT jack to the 1788A’s MIDI
IN jack.
Controlling Multiple 1788A’s
Additional units can be stacked by connecting the MIDI THRU to the next MIDI IN, and so-on.
If the added 1788A’s are kept on the same MIDI channel, they must be given different MIDI
device numbers.
The next step would be to program the additional controls on the MIDI controller with SysEx
strings associated with the additional MIDI device numbers. For example, if one additional
1788A is used, the second set of eight faders and buttons of the PC1600 could be coded
