Keyboard Splits
Unlike most instruments, the B4 must implement multiple keyboard ranks
(called manuals in organ parlance). This is accomplished in two ways: either
by responding to multiple MIDI channels, or by supporting keyboard splits.
When using multiple MIDI channels (No Keyboard Split), the default response
to MIDI information is as follows:
Notes, Controls, and Program Changes received on MIDI channel 1 are used by
the entire instrument. Program Changes received on channel 1 are equivalent
to selecting a preset from the upper manual preset keys.
Notes, Controls, and Program Changes received on MIDI channel 2 are used by
the lower manual. Program Changes received on channel 2 are the equivalent
of selecting a preset from the lower manual.
Notes and Controls received on MIDI channel 3 are used by the bass pedals.
Program Changes received on channel 3 are treated as if received on channel
2.
You can change these default settings by choosing different MIDI channels
on the Setup View. Please refer to the corresponding section in this manual
for further information.
Using this method for handling MIDI data, it is easy to maintain production
control from your sequencer or multiple MIDI keyboards.
When using keyboard splits, the MIDI information received on MIDI channel
1 is sent to the different manuals based on the keyboard split locations. In
all cases, the upper manual is controlled using the highest MIDI notes, and
the pedals are controlled with the lowest notes.
Using the keyboard split mode, it is easy to play all three manuals “live” with
just one keyboard, allowing a skilled player to simulate the complex manual
control of a hot B3 player.
Setting Split Points
To split the notes received on MIDI Channel 1 between the B4’s upper and
lower manuals right-click with your mouse on the desired key on the on-screen
keyboard.
