5. OSC1 (Oscillator 1)
broaden the pitch difference between the
oscillators, producing a richer sound.
Knob [4] Control2: Phase [000…127]
Specifies the phase of each oscillator at
note-on. This will affect the tone of the at-
tack. A setting of 127 will change the pitch
and volume.

Adjusts the depth of VPM.

Processing an external audio signal
You can use the filter, amp, EG, and LFO
etc. to process the signal from a external
synthesizer, rhythm machine, or audio de-
vice in the same way as an oscillator wave-
form.
Before you connect an external device,
turn off the power of the R3 and of any
external output devices and power
amps.
1 Turn the [AUDIO INPUT 1] and
[AUDIO INPUT2] knob to the MIN
position, and
set the [MIC] switch
to REAR
.
2
Connect the output jacks of your ex-
ternal device to the [AUDIO INPUT
1] jack and [AUDIO INPUT 2] jack,
and set the AUDIO INPUT 1 [MIC/
LINE] switch to LINE.
3 After making connections, turn the
power on to your external device,
the
R3, and your powered monitor
speaker system - in that order.
4 Select a synth program and initial-
ize it (hold the [SHIFT] button and
press the PROGRAM SELECT [2]
button. Press the blinking [2] but-
ton to initialize;
[EXIT]
to cancel.(
p.75).
5 Turn the [PAGE] dial to the 5. OSC
1 page, and set “WAVE” (knob [1])
to AudioIn.
6 Send an audio signal from the exter-
nal device, and turn the [AUDIO IN-
PUT 1] and [AUDIO INPUT2] knob
toward MAX as far as possible with-
out allowing the AUDIO INPUT 1 and
AUDIO IN 2 LED to light red.

tone generator module, rhythm machine,
or audio device
7 While inputting an audio signal,
play the keyboard.
8 Edit the FILTER, AMP, EG, LFO, and
effects as described in “Basic edit-
ing procedure” (p.19), to modify
the sound.
The PITCH-related parameters have
no effect on the sound from the [AU-
DIO INPUT 1] and [AUDIO INPUT 2]
jacks.
In this example, you could connect the
R3’s MIDI OUT to the MIDI IN of your
external MIDI device and set the MIDI
channels to match, so that your sound
module or other external MIDI device
will produce sound when you play the
keyboard of the R3 (p.64). You can
use the R3’s keyboard to play the
sounds of your external device, and use
the [PAGE] dial and the CONTROLS
[1][4] knobs to modify the sound.
You can use an external input as the
carrier of the vocoder.
If the 2. Unison page “Sw” (knob [1])
is On (2–4 Voice), certain parameters
are automatically set to allow the au-
dio input to be handled in stereo. In
this case, please note the following
points.
•Regardless of the OSC1Ctr2: Balance
setting, the L-channel signal will be
fixed at L63 and the R-channel sig-
nal at R63.
Regardless of the 2. Unison page
“Sw” setting, this parameter will be
fixed at 2 Voice.
If the 2. Unison page “Spread” pa-
rameter (knob [3]) is set to 0, both the
L-channel and R-channel of the tim-
bre output will be panned (
p.37
12.
Amp page “Panpot” parameter) to
CNT. If the “Spread” parameter is set
to 127, they will be set to L63 and
R63.
