Roland EM-50 User Manual

Here are some of the parts whose MIDI channels you
can set:
Lower (avaìlable in Organ mode)
M.Bass (available in Organ mode)
A.Drums (Arranger drum part)
ABS
A. Bass (Atranger bass part)
AC1-AC6 Melodic Arranger parts (that play chords or riffs)
TxRx means “MIDI transmit and receive channel”.
The setting range is 1~16 (the number represents the
MIDI channel). Select “Off” if you don't want a part
to receive or transmit MIDI messages.
RX1, RX2, RX3
(1~16, Off, Default: Off) Your EM-50/30 has three
parts (“musicians”) that can only be played via MIDI.
That is, you cannot trigger them on the instrument
itself — hence the name “RX” (receive). If you work
with a sequencer or an external MIDI controller, how-
ever, these parts can be used for playing additional
lines of your sequence.
At first (and everytime you initialize the EM-50/30's
MIDI parameters using the Resume function), these
parts are set to “Off” and therefore do not receive
MIDI messages. You can, however, activate them by
assigning them a MIDI channel. Be careful not to
select a MIDI channel you have already assigned to
other EM-50/30 parts. The channels you could use
are: 13, 14, and 15, provided you select “Off” for
NTA1, NTA2, and Basic Ch.
NTA1/2 Rx (Note-to-Arranger 1/2 Rx channel)
NTA is short for “Note-to-Arranger’, or the notes you
play in the left half of the keyboard to feed the
Arranger with chord information. These notes can
also be received via MIDI. If you want the Arranger to
use these notes, you must transmit them on the MIDI
channels assigned to the NTA function (from your
computer or external MIDI instrument to the EM-50/
30).
You probably noticed the plural in “channels”. There
are indeed two NTA receive channels so that you
could use the EM-50/30 as realtime arranger module
for a MIDI accordion or any other MIDI instrument
capable of transmitting on two channels.
You could also take advantage of these two NTA chan-
nels to control the Arranger from two external master
keyboards or a PK-5 MIDI bass pedal unit.
There is no Tx parameter for the NTA level. The notes
you play on the EM-50/30's keyboard are indeed
transmitted to the Arranger, from there to the
Arranger parts, and used to play the accompaniment
in the right key. Since all Music Style notes are trans-
EM-50/30
mitted via MIDI, there is no need to send the NTA
notes separately.
Before setting the (or just one) NTA receive channel,
see the manual of your external MIDI controller to
find out which channel(s) it transmits on.
Possible values: Off, 1-16 (may not be the same as
NTA2). Default: 14 (NTA1) and 15 (NTA2).
Style Ch (Style Select TxRx Channel)
As its name implies, the Style Select channel is used to
receive and transmit program changes that cause the
EM-50/30 or the receiver to select another Music
Style. Note that the Custom Style memories (and the
EM-50's Disk User memory) can also be selected via
MIDI.
Possible values: Off, 1 — 16. Default: 10.
Basic Ch (Basic TxRx Channel)
The Basic Channel is the MIDI channel used for
receiving and transmitting Program Change and Bank
Select messages relating to the selection of User Pro-
grams. In other words, every time you select a User
Program on your EM-50/30, it will send a series of
MIDI messages to the MIDI OUTput on the MIDI
channel you select here.
Likewise, if the EM-50/30 receives a series of messages
(Bank Select and Program Change) on the Basic
Channel, it will select the User Program that is
assigned to the numbers contained in the received
MIDI messages.
Possible values: Off, I ~ 16. Default: 13.
MIDI data filters
The following parameters allow you to decide whether
or not certain MIDI message types should be received
and transmitted.
ProgChng (Program Change)— This filter allows you
to enable (On) or disable (Off) the transmission and
reception of Program Change messages. These mes-
sages are used to select Tones, Styles, or User Pro-
grams.
Possible settings: Off, On. Default: On.
Note: The setting of this parameter also applies to the
parameter of the same name in Song mode (see page 54).
PitchBnd (Pitch Bend)—This filter allows you to
enable (On) or disable (Off) the transmission and
reception of Pitch Bend messages. These messages are
used to temporarily increase or decrease the pitch of
the notes (Upperl, Upper2, or M.Drums parts).
Possible values: Off, On. Default value: On.
Note: The setting of this parameter also applies to the
parameter of the same name in Song mode (see page 54).
