Keyboard Modes - Roland A-37 Owner's Manual

4. Keyboard modes

Owner's Manual
Your A-37 has three buttons that allow you to select
one of four Keyboard modes. The KEYBOARD MODE
determines how many zones and/or MIDI channels
can be used simultaneously.
Whole Upper
Upper section assigned to all keys
This mode means that the Upper section is assigned
to the entire keyboard. All messages generated on
the A-37 are therefore transmitted on the Upper
channel. Press the [UPPER] button to select this
mode.
Whole Lower
Lower section assigned to all keys
This mode means that the Lower section is assigned
to the entire keyboard. All messages generated on
the A-37 are therefore transmitted on the Lower
channel. Press the [LOWER] button to select this
mode.
Alternately pressing [UPPER] and [LOWER] allows
you to control different MIDI instruments as and
when needed. Example: you could use the Lower
section for controlling an organ sound of one mod-
ule (or part), and the Upper section for playing a
lead synthesizer part using a different MIDI instru-
ment.
8
Split
Lower section
In Split mode, the Lower section is assigned to the
left half of the keyboard, while the Upper section is
assigned to the right. This allows you to control two
different MIDI instruments via separate channels
(Lower and Upper). Press the [SPLIT] button to select
this mode.
At first, the Split point is located at the "C" key
slightly left off center. This key is called the C4.
Here's how to select another split point between the
"F1" and the "Gb7" (see the following illustration):
Possible range for the Split point
(1) Press and hold the [SPLIT] button.
(2) While still holding that button, press the key that
should become the lowest note of the Upper sec-
tion.
You can also use the [DOWN]/[UP] buttons.
(3) Release both the [SPLIT] button and the key you
pressed.
Note: This setting can be saved to a Patch. Your KEY-
BOARD MODE selection is also saved.
Note: To return to the default setting (C4), simultane-
souly press [DOWN]/[UP].
Layer (Lower + Upper)
Lower section + Upper section (two different MIDI channels)
In Layer mode, the A-37 transmits on two MIDI
channels simultaneously (assigned to Lower and
Upper). Every action on the A-37 is thus translated
into two MIDI message strings. Hold down [LOWER]
while pressing [UPPER] to select this mode.
To leave it, press [LOWER], [UPPER], or [SPLIT].
