External Program Recall
Programs may be recalled externally using a user-built 9-pin interface on the PROGRAM CONTROL port or by using an
AirTools RC-1 MIDI controller. Additionally, any generic MIDI controller which can send MIDI Program Change messages will
work.
PROGRAM CONTROL:
The PROGRAM CONTROL port is a standard 9-pin D-sub connector which allows program loading on
each channel using standard contact closures. Interfacing with the PROGRAM CONTROL port allows
the user to integrate the 6200 into a purpose-built work surface.

Until support for a remote LCD is fully implemented, program scrolling/loading is a blind process. There is no
front panel indication of any actions on the PROGRAM CONTROL port.
MIDI/RC-1 IN:
The 6200 responds to MIDI Program Change messages from the AirTools RC-1 Remote or from any MIDI device capable of
sending MIDI Program Change messages. The RC-1 allows direct recall of up to 11 programs as well as the ability to enable/
disable the DSP BYPASS function.
The RC-1
The RC-1 does not provide selection or change of any individual processing parameters within the 6200’s programs. It
merely selects and loads up to 11 sequential programs (plus DSP Bypass).
Changes to the 6200’s processing parameters must be made at the
unit’s front panel or by using the optional 6200 Designer software. There
is no button lockout or other security feature provided on the RC-1. If
you accidentally hit one of the buttons, you will accidentally change the
processing program on the 6200.
The RC-1 connects to the 6200 with the included 25-foot, 7-pin DIN cable.
The 6200 and RC-1 exchange MIDI information on pins #2 and #3. The
6200 provides power for the RC-1 on pins #1 and #7. Pin
#7 is +V; pin #1 is ground. To preserve compatibility with
other MIDI devices, the remaining pins on the connector are not used.
If you connect the 6200 to a MIDI
controller other than the RC-1, make sure you use a cable which does not have Pin #7 connected.
Caution:
The RC-1 includes a jack for an optional 9 VDC power supply providing at least 30 mA (not
supplied). If you use the RC-1 with the 6200 and the supplied 7-pin DIN cable, the RC-1 takes its power
from the 6200.
No external power supply is required when using the RC-1 with the 6200 and the
provided cable.
The optional 9 VDC connection allows you to use the RC-1 with other MIDI controlled
devices which to not supply power. NOTE: Symetrix does not make, sell or recommend a power supply.
You will notice that none of the LEDs on the RC-1 are lighted when it is first plugged in. This is normal; the LEDs serve as tally
lights indicating which button was pushed last. The LEDs do not provide positive confirmation from the 6200 that the program
selected was loaded by the 6200. The RC-1 will not reflect a change in program selection made at the front panel of the 6200.
The LEDs on the RC-1 serve as reminders of which button on the RC-1 the user pressed last. (MIDI communication is one-
way, from RC-1 to 6200.)
