Sin
Sine wave is a mild tone that contains only the funda-
mental frequency with no overtones.
When “OSC Mod” = Waveform
Control1: Waveform (Waveform Modulation) [000…127]
A setting of 0 produces a simple sine wave. Increas-
ing this value will modify the waveform as follows,
changing the overtone structure.
Control2: LFO1Mod (LFO1 Modulation Intensity) [000…127]
Adjusts the depth to which LFO1 will affect the
“Control1” effect.
When “OSC Mod” = Cross
This is the same as when “Wave” = Saw.
When “OSC Mod” = Unison
This is the same as when “Wave” = Saw.
When “OSC Mod” = VPM
This is the same as when “Wave” = Saw.
Formant
The formant waveform has a tonal character reminis-
cent of a human voice.
Control1: Formant (Formant Width) [000…127]
Adjusts the frequency components that are charac-
teristic of vocal formants. This is equivalent to
changing the shape of your mouth (i.e., changing
the vowel sound).
Control2: Offset (Formant Offset) [–63…+63]
Moves the entire formant frequency spectrum
upward or downward. This is equivalent to chang-
ing the size of your mouth. A setting of 0 produces
the standard formant locations.
Noise
Generates noise. “Control1” boosts the pitched compo-
nent within the noise, and “Control2” adjusts the bright-
ness.
Control1: Resonance [000…127]
Adjusts the amount of resonance for the filter pro-
vided within the noise oscillator. Higher values will
emphasize the frequency points for the pitched
component within the noise.
Control2: LPF/HPF [LPF63…CNT…HPF63]
Adjusts the mix balance between the low-pass and
high-pass filters; this will vary the brightness of the
sound.
SynthPCM
This provides various PCM waveforms taken from
acoustic instruments and digital synthesizers. You can
choose one of 64 different PCM waveforms.
For details on the PCM waveforms provided, refer to
p.156 “Voice Name List.”
Control1:
--- has no effect
Control2: Wave Sel (Wave Select) [01…64]
Selects the PCM waveform.
DrumPCM
This provides various PCM waveforms such as drum
and percussion sounds.
Control1: Pitch (Drum Pitch) [–63…+63]
Adjusts the pitch.
Control2: Wave Sel (Wave Select) [01…128]
Selects the drum PCM waveform. The pitch of the
drum PCM waveform will be the same regardless of
the note number. You can choose one of 128 differ-
ent drum PCM waveforms.
For details on the drum PCM waveforms provided,
refer to p.156 “Voice Name List.”
AudioIn
This lets you use the input source specified by “Source”
as the oscillator output.
Control1: Gain [–63…+63]
Adjusts the volume of the audio input.
Control2: Balance [L63…CNT…R63]
Adjusts the balance between the L channel (INPUT
1 jack) and R channel (INPUT 2 jack) of the input
signal.
If the P04–2: VOICE – UNISON tab page “Sw” is
On, the audio input can be used as stereo, and cer-
tain parameters will be set automatically. In this
case, please note the following points.
• Regardless of the “Balance” (Control2) setting,
the signal of the Int.Bus L or Ext.In 1 signal
will be fixed at “Balance” = L63, and the signal
of the Int.Bus R or Ext.In 2 signal will be fixed
at “Balance” = R63.
• The oscillator will be fixed at “2 voice” regard-
less of the “Unison Mode” setting.
• If “Unison Spread” is set to 0, the L channel
and R channel of the timbre output will both
be set to a “PAN” of CNT (Center). If “Spread”
is set to 127, the L channel and R channel of
the timbre output will be set to a “PAN” of
L63 and R63 respectively.
2: Source [ExtIn, IntBus]
Selects the audio input source.
This is valid only if “Wave” is set to AudioIn.
Use Control1 “Gain” to adjust the input volume, and
Control2 “Balance” to adjust the balance.
ExtIn
The waveform received from the INPUT 1 and 2 jacks
will be used. The input from the INPUT 1 jack is sent to
the L channel of the oscillator, and the input from the
INPUT 2 jack is sent to the R channel. If the P4–2: VOICE
– UNISON tab page “SW” setting is Off, the sound will
be mixed to monaural.
IntBus
The internal bus will be used. The input from the L chan-
nel of the bus is sent to the L channel of the oscillator,
and the input from the R channel is sent to the R channel.
