Yamaha RX-15, Authorized Product Manual

Page: 24 / 40

The desired sync mode is selected by pressing the
SYNC button while holding down the FUNCTION button.
Normally, the LCD panel will read “INTERNAL CLOCK”
indicating that the internal sync mode is selected. To
select other modes, press the –1/NO button. Each
press of the –1/NO button cycles the sync mode in the
following order: INTERNAL– MIDI – EXTERNAL –
INTERNAL – etc. Set the display to the desired mode
then press + 1 /YES activate that mode.
If the EXTERNAL mode is selected, the “TIME
BASE=24/
” display will appear. By using the + 1/YES
and –1/NO buttons a time base of 24/ ,48/ , or
96/ can be selected, according to the type of sync
signal to be received. The numbers 24, 48 and 96
correspond to the number of clock pulses per quarter
note. Once the time base has been set, press the SYNC
button to exit.

MIDI Reception Parameters
Three main parameters must be set in order to receive
MIDI data:
1 — RECEIVE AVAILABLE/UNAVAILABLE — This
parameter simply turns MIDI KEY NUMBER reception on
or off. “RECEIVE AVAIL” = MIDI KEY NUMBER
reception is ON, “RECEIVE UNAVAIL” = MIDI KEY
NUMBER reception is OFF.
2—OMNI MODE ON/OFF— When the OMNI mode is
ON, the RX15 will receive MIDI data on all 16 available
MIDI channels. This is the mode that will normally be
used in setups where one MIDI transmitting device (a
sequencer, etc) is controlling only the RX15. In some
systems, however, the MIDI transmitting device may be
required to control several different MIDI receiving
devices in different ways. In this case, the OMNI mode
must be turned OFF and the RX15 set to receive only on
the MIDI channel containing pertinent data.
3—RECEIVE CHANNEL (1 through 16)— When the
OMNI mode is turned OFF, the RX15 must be set to
receive MIDI data on a specific channel. The sequencer
or music computer used to transmit the MIDI data might,
for example, be transmitting melody data to a
synthesizer on channel 1, and rhythm data to the RX15
on channel 2. The RX15 must therefore be set to receive
on channel 2 only, to prevent the melody data from
triggering the rhythm machine.
In some cases it may be necessary to continue and set
the instrument key numbers as described in the
“Instrument Key Numbers” section, below.
All these parameters are set by first entering the MIDI IN
programming mode: press the MIDI IN button while
holding down the FUNCTION button. The first display in
response to this will normally be “RECEIVE AVAIL”
(default parameter). This means that the RX15 is ready to
receive MIDI data. To turn MIDI reception OFF press the
–1/NO button, causing the display to read “RECEIVE
UNAVAIL”. Each press on the –1/NO button alternates
between the “AVAIL” and “UNAVAIL” settings. Select
the required mode and press the MIDI IN button to
activate it. The MIDI IN mode will be exited if
“UNAVAIL” is selected. If “AVAIL” is selected, the LCD
panel will then read “OMNI ON” (default parameter),
indicating that the OMNI mode is on. If the OMNI ON
mode is then activated by pressing the MIDI IN button,
the MIDI reception parameter setting process is
complete. If the OMNI mode is turned OFF by pressing
the –1/NO key (pressing the –1/NO key alternates
between the “OMNI ON” and “OMNI OFF” modes) and
then activated by pressing the MIDI IN button, the RX15
will prompt you to set the MIDI receive channel with
“RECEIVE CH = 01” (default parameter). The desired
MIDI receive channel is then selected using the DATA
ENTRY control. Once the channel has been selected, it
is set by pressing the MIDI IN button.
