voices are activated on the OXFORD 940 via four MIDI coupler pistons. The MIDI channels these
coupler pistons control are:

SENDING A PROGRAM CHANGE
1. Hold SET and press a MIDI coupler piston. The piston will flash, indicating the MIDI
Set Mode is active. When the MIDI Set Mode is entered, the following display window
will show the parameters:

2. Choose the desired Program Change (sound), and press the corresponding key (see the
Program Change chart). Once the key is pressed, the display window will revert to the
Transposer.
If SET is held while pressing a key to send a Program Change, the Program Change will be
sent, but the MIDI Set Mode will be "locked on." Once this has happened, further Program
Changes may be sent by holding SET and pressing a corresponding key. This allows the organist to
try several sound selections until the appropriate one is found. The MIDI Set Mode will remain
active until the flashing MIDI coupler or General Cancel is pressed.
Once a Program Change has been sent on a MIDI coupler, that same Program Change will be
sent each time the piston is activated. The Program Change will also be saved on any combination
piston including that MIDI coupler.
When the MIDI coupler parameters are being shown in the display window, the SELECT knob
may be used to alter the Program Change number. By holding SET and turning the SELECT knob,
the cursor can be moved to the other coupler parameters, which can also be altered by the SELECT
knob.
If no Program Change is to be sent by a coupler, the Program Change number may be set to OFF
by pressing a key which has no associated Program Change number (see chart) or by turning the
SELECT knob past Program #128 until PGM OFF is displayed.
