Powering Up - Roland A-37 Owner's Manual

Working with a computer or sequencer
If you want to use the A-37 as Master keyboard for
recording applications that involve a computer with
sequencing software or a hardware sequencer (like
the Roland MC-80), here is the most useful connec-
tion system:
A-37 (transmits MIDI
messages)
Computer or sequencer
(records and transmits
MIDI messages)
Module, synthesizer, etc. (receives MIDI messages)
This setup only works as expected if the following
conditions are met:
• The computer (if that is what you use) must be
equipped with a MIDI interface.
• You need to switch on the sequencer's MIDI Soft
Thru/MIDI Echo function. Otherwise you won't hear
what you are playing. (See the sequencer's/soft-
ware's manual for details.)
Note: The MIDI channel you set on the A-37 (see p. 11)
may be changed to another number by the sequencer.
If that is not the case, be sure to set at least one of the
A-37's zones to the MIDI channel the module (not the
sequencer) is receiving on.
Note: Yet other configurations are possible, but the
above usually cover most of your MIDI needs. You
could connect the MIDI IN socket of a second module
to the a MIDI THRU socket of the module pictured
above for an even larger system.
Or you could establish the following connection:
[Sequencer] MIDI OUT [A-37] MIDI IN
[A-37] MIDI THRU [Module] MIDI IN
(Alternative: [A-37] MIDI OUT A
see also "About MIDI Thru" (p. 16)).
Note: It is also possible to use the A-37 MIDI OUT A
and MIDI OUT B sockets simultaneously for controlling
two separate MIDI chains.
MIDI OUT A or B
MIDI IN
MIDI OUT
MIDI IN
[Module] MIDI IN,

3.4 Powering up

Power to the various devices should be turned on in
the appropriate order. First, turn on the units that
transmit MIDI messages (computer, A-37). Next,
turn on the sound module(s)/synthesizers, then the
amplification system.
Set the A-37's power switch (rear panel) to the ON
position.
Power off your system in the reverse order.
Note: The A-37 is equipped with a circuitry protection
feature. At power-up, a brief interval is required before
it will operate normally.
Note: If the A-37 is powered using batteries, be sure to
switch it off whenever you are not planning to use it
for a while (5 minutes or more). But before doing so,
you may wish to save the current settings to a Patch
memory (see p. 16).
