6. 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
the organ. 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, this is helpful when reassigning an external
MIDI device from one organ division to another.
Important!
The Base Channel always resets to Channel 1 whenever the organ is turned
on.
Advance to the 'MIDI BASE CH' window function
(see Section A-2)
.
Press the
CURSOR
button until the cursor is positioned on the MIDI Base Channel
value. Turn the
ROTARY DIAL
to change the MIDI Base Channel value. 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 will be transmitted and received
on MIDI Channel 1 (
See Section C-1 for Allen MIDI Channel Assignments
).
If the Base Channel is set to 2, all of the channels will shift higher by one. Now; Swell =
2, Great = 3, Pedal = 4 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.
7. MIDI Expression Settings
Advance to the 'MIDI EXPRESSION' window function
(see Section A-2)
.
There are four modes for transmitting expression data via MIDI. To select an expression
mode, press the
CURSOR
button until the cursor is positioned on the expression setting
value (line 2) of the display. Turn the
ROTARY DIAL
to select one of the four different
expression modes.
Note:
The default expression mode setting is always POLY-VOLUME.
POLY-VOLUME —
This is the normal expression mode setting where 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 setting 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:
This mode setting should only be used if your Allen Organ does not contain
velocity sensitive keying.
