Data Parameters - Roland A-37 Owner's Manual

[5] oct (Octave)
This parameter is especially useful in Split mode (see
p. 8), when you wish to use your left hand for a
chord backing whose register is close to the part you
play with your right hand. Of course, you can also
transpose (or "shift") the Upper part in octave steps,
which may be useful in Layer mode.
The setting range is –2, –1, 0, 1, 2 octaves (down or
up). Note that the A-37's keyboard can also be
transposed in semitone steps. See page 16.
[6] aft (Aftertouch)
The A-37's keyboard transmits channel Aftertouch
messages – if you want it to. Select 0n if the active
section should indeed do so. Select 0FF to keep a
section from transmitting Aftertouch messages.
Especially when working with a sequencer, it is usu-
ally wiser to select 0n only if you really want After-
touch messages to be recorded. Aftertouch indeed
generates a continuous stream of values that take
up a lot of memory. If the receiving MIDI instrument
does not respond to them, it would be a good idea
not to transmit them in the first place.
Note: "Channel Aftertouch" refers to the fact that only
one Aftertouch value (the highest) is transmitted at
any one time, even though you may be playing chords.

5.3 DATA parameters

The DATA parameters represent MIDI messages you can use for configuring the receiving MIDI instrument up to a cer-
tain point by specifying things like its main and expression volume, its Reverb and/or Chorus depth, etc.
These are "static" settings that are transmitted whenever you select a Patch. With the exception of ch, mde, and dmp,
the corresponding control change numbers can also be assigned to the DATA ENTRY slider for continuous realtime
control (see p. 10).
Note: Be sure to select 0FF for any MIDI message that
should not be transmitted.
Note: See page 9 for how to select and set these
parameters.
[0] ch (MIDI channel)
This parameter allows you to assign the desired MIDI
channel to the Upper or Lower section. In fact, this
parameter does two things at a time:
• it specifies the MIDI channel (1~16)
• it specifies the MIDI OUT socket via which the sec-
tion's MIDI messages are transmitted (A or B).
[7] ftp (Foot Pedal/Expression)
Upper, Lower
This parameter allows you to specify whether the
selected section should (0n) or should not (0ff)
transmit expression (CC11) messages.
The third possibility, inU, is very interesting indeed
for the Layer mode (see p. 8): by assigning 0n to the
Upper section, and inU to the Lower section, for
example, you can increase the volume of the Upper
MIDI channel and simultaneously decrease that of
the Lower MIDI channel by pressing the pedal down
(toe down) – and vice versa. This allows for some
nifty "sound morphing".
Upper, Lower
This parameter is only relevant if you connect an
optional EV-5 or BOSS FV-300L expression pedal to
the A-37's FOOT PEDAL socket.
[8] bch (Battery Check)
This parameter allows you to check the voltage of
the batteries (0~100). The value "0" means that the
batteries should be dead by now, while "100" repre-
sents the highest value. A dot in the left part of the
display will flash whenever the battery power is less
than 30%.
Note: This value is only meaningful if no adaptor is
connected to the DC IN socket (if an adaptor is con-
nected, the value will always be 100).
Note: For important occasions, it may be wiser to work
with an optional ACA adaptor. That way, you can rest
assured that you will not run into problems during the
session or gig.
Here is an example: if you select 11b for the Upper
section, it will transmit its messages on MIDI chan-
nel "11" to MIDI OUT B. Though you can also select
0FF (by simultaneously pressing [DOWN]/[UP]),
there is little point in doing so. After all, you can
achieve the same result by switching off the KEY-
Upper, Lower
BOARD MODE button of the section you do not
need.
