Rodgers

gives the updated status of
all
stops and couplers. Each
of these SysEx messages, then, communicates the
status of the entire instrument.
If desired, the 538/i548 can transmit Program Changes
when registration memories are selected on the organ.
These messages only communicate which pistons are
pressed, not the status of stops and couplers. This is
often useful when controlling the 538/i548 from a
remote MIDI keyboard that sends Program Changes or
from a different model of Rodgers organ. The Program
Changes are sent and received on one of the Master
Channels.
System Exclusive messages, on the other hand, provide
optimum control over registrations, both those made
by pressing pistons and those changed by hand. Factory
default settings of both “Send” and “Receive” are set to
“Stops & Pist” (System Exclusive messages). Available
options are: “Stops”, “Pistons” (Program Change
messages), “Stops & Pist”, and “Off”.
(1) Press

.
(2) Use the Select knob to select “MIDI Setting”.
(3) Confirm your choice by pressing
[QUICK¥MENU]

(4) Choose “General” with the Select knob.
(5) Confirm your choice by pressing
[QUICK¥MENU]
.
(6) Use the Select knob to choose the “Rcv” (reception
of “Stop Change” messages) or “Snd” (transmission
of those messages), depending on what yo want to
set.
(7) Use the data entry wheel to select the desired
option.
(8) Save your settings if you wish to keep them.

Using pistons to control a second Rodgers organ
In cases where two Rodgers organs are available, it is
possible to play either or both instruments from one
location. In these setups, the controlling console is
referred to as the “Master” and the console played
from a remote location is known as the “Slave”.
In order for the two consoles to communicate, a MIDI
connection must be made between the MIDI OUT jack
of the Master console and the MIDI IN jack of the
Slave. (A number of third-party companies make
special systems to transmit MIDI over long distances.)
Once this connection is made, the Master console can
access the resources of the slave console. Most often,
it is best to use pistons to control registrations at
both locations; when a certain piston is pressed on
the Master console, the same piston is selected at the
Slave console.
To set up both consoles so that pistons are used to
control registrations:
• Select “Pistons” for the “Stop Change – Snd” parame-
ter on the Master console.
• Select “Piston” or “Stops & Pist” for the “Stop Change
– Rcv” parameter on the Slave console.
After this setup is accomplished, selecting a memory
on the Master console will also select that memory
on the Slave console. The contents of each memory
can be different.
If there are times you want to use the resources of
one instrument alone (i.e., the other is silent), select a
registration memory on the console to be heard and
prepare the same memory on the other console in
such a way that it contains no active stops. That way,
even though a memory is selected on both the
Master and the Slave console, only the instrument
that has active stops activated will be heard.
Note:
You can also use “Local” to silence the desired divisions
on the Master console.
Seq. Update
MIDI sequencers generate MIDI messages when they
start and stop, namely “Start”, “Stop” and “Continue”.
The 538/i548 uses these sequencer messages to
automatically record the registration and expression
shoe status at the beginning of a sequence. When a
MIDI Start command is received, the organ sends the
status of all stops and couplers plus the position of the
expression shoes to the sequencer; the initial status of
the organ is therefore recorded in the sequence and
later recreated during playback.
The organ also sends Program Change, Bank Select and
Expression information for all active MIDI couplers
when a Start command is received.
The “Seq. Update” (“Sequencer Update”) parameter in
the “MIDI Settings – General” menu defines how the
organ responds to Start, Stop and Continue messages
sent from a sequencer. When the value is set to “On”,
proper communication is ensured. This is the
configuration that should be used in the vast majority
of applications. When set to “Off”, the organ does not
respond to Start messages; this configuration is
reserved for very specific uses and won’t be applicable
to most users.
Most hardware sequencers (like the Rodgers MR-200)
transmit Start, Stop and Continue values automatically
unless you manually disable them. Some software
