D. MIDI FUNCTIONS
This section explains the MIDI capabilities of the Allen Organ. Knowledge of this section is
not required for everyday use of the organ, normal service playing, or use of Allen
SmartMIDI™ devices. This information’s usefulness will ultimately be determined by your
needs, along with the type and capabilities of any external MIDI devices you choose to use--
e.g., sequencers, voice/sound modules and external MIDI keyboards. The MIDI topics
covered by this manual are limited in scope. A basic understanding of the terms MIDI IN,
OUT and THRU and their basic functions are required. To increase your understanding of
MIDI and its capabilities it is suggested that books or literature be referenced which describe
how to use MIDI.
Note: Please consult the owner’s manual of the external MIDI device(s) being used for more
details of their operation.
1. Standard MIDI Channel Assignments
These are the Allen Organs’ standard MIDI channels settings:
LD-34b
Channel Organ Division
1 = Swell
2 = Great
3 = Pedal
8 = General
Note: The MIDI Base Channel always resets to Channel 1 whenever the organ is turned on.
2. Selecting Program Change Modes
Program change modes establish how MIDI program changes are sent from the organ when a
piston is pressed. Once a particular program change mode is selected, the organ will retain
the same program change mode (even when the organ is turned off) until a new program
change mode is selected. These three mode options determine how the organ sends program
change information to MIDI devices.
Selecting a Program Change Mode
To access the Program Change mode function, touch:
OPTIONS >> MIDI >> PROGRAM CHANGE & DISPLAY OPTIONS
Important! It is important to understand how to
operate and when to use each of these modes before
they are changed!
Program Change Modes:
PRESET Mode: This mode causes the organ to send a
program change number equal to the piston number
that is pressed. Preset mode also causes the organ to
transmit the capture memory level value whenever the
capture memory level is changed or whenever the CANCEL piston is pressed. General
Pistons will send program changes 1-10 on MIDI Channel 8, the organ’s General Piston
control channel. The Divisional Pistons for each division will send program changes on the
respective MIDI channels as shown above.
