Changing The Midi Base Channel - Allen Organ Company Quantum User Manual

CHANGING the MIDI BASE CHANNEL

This function allows you to change the setting of the MIDI Base Channel. The Base Channel is a
reference point to establish the positioning of the other 15 MIDI channels. On Allen Organs, the
Base Channel equals the Swell Division's channel of transmission (i.e., if the Base Channel = 1,
then the Swell Channel = 1, if the Base Channel = 2, then the Swell Channel = 2, etc.). Moving
the Base Channel allows you to shift the organ's range of MIDI channels, helpful when
reassigning an external MIDI device from one organ division to another. Note: The Base
Channel always resets to Channel 1 whenever the organ is turned on.
Advance to the 'MIDI BASE CH' window function:
Use the "▲" and "▼" buttons in the Console Controller™ to change the Base Channel. All
functions associated with a particular division will transmit and receive on its assigned channel.
For example, MIDI Channel 1 is normally assigned to the Swell Division and the Swell Manual.
Therefore, keying velocity or on/off messages, and program changes (Swell Divisional Pistons)
will be transmitted and received on Channel 1 (See Section C-1 for Allen MIDI Channel
Assignments).
If the Base Channel is reset to 2, in the display all of the channels will shift higher by one. Now,
Swell = 2, Great = 3, Pedal = 4, Choir = 5, and the General Pistons = 9. Note: MIDI Channel
numbers will wrap, i.e. channel numbers go only to 16 and will then repeat to 1. FOR NORMAL
USE, DO NOT USE A BASE CHANNEL LARGER THAN 9.
7. MIDI EXPRESSION SETTINGS
Advance to the 'MIDI EXPRESSION' window function.
There are four modes for transmitting expression data via MIDI. They are selected by pressing
the "▲" and "▼" buttons in the Console Controller.
POLY-VOLUME — This setting will always be selected when the organ is turned on. In this
mode the expression data is distributed among the appropriate MIDI channels. This is the proper
mode to use when recording to, or playing back from, a sequencer.
POLY-VELOCITY — This mode should be selected if you are using a percussion-type voice
from a sound module or an external MIDI keyboard. For example, if a digital piano sound were
played from the organ keyboard through MIDI Channel 1, the piano could be made to sound more
realistic. By opening the Swell expression shoe, the piano strings would appear to be struck
harder than when the Swell pedal was in the closed position. Note: In POLY-VELOCITY mode,
all expression information is sent in key velocity form. Changes in velocity will occur only when
a new key is struck. Consequently, if you change the position of the Swell pedal after a key is
struck there will be no change in velocity until a new key is struck. Use this mode only when a
velocity-sensitive external MIDI device is connected. If this mode is selected when recording to a
sequencer, the expression on the organ will not function when playing back from the sequencer.
