OSC2 Pitch Ofs (OSC2 pitch offset)
–1 octave ... 4 octaves
Specify the pitch of OSC2 relative to the pitch of OSC1.
The pitch of OSC2 can be adjusted in the range of –1 octave
to 4 octaves from the pitch of OSC1.
The pitch of OSC1 will be the pitch that sounds when you
use the keyboard function or the pitch specified for a phrase
pattern.
OSC1 Wave ...Audio In
Specify the basic waveform of OSC1.
(sawtooth wave)
This waveform is rich in overtones, and is suitable for
bass or synth lead sounds.
(square wave)
This waveform contains only the odd-numbered har
monics, and produces a tone typical of electronically
produced sound.
(triangle wave)
This waveform is more mellow than the sawtooth wave
or square wave, and is suitable for sub-bass sounds etc.
Audio In
The audio signal input from the audio input jack will
be used as OSC1.
So that they will be particularly suitable for bass sounds,
the waveforms of OSC1 have a slightly heavier sound (fun-
damental) than the waveforms of OSC2.
OSC2 Wave , ,
Specify the basic waveform of OSC2 (refer to OSC1 Wave).
When OSC Mod is set to Deci, the basic waveform
selection will have no effect.
OSC Mod (oscillator modulation)
off, Ring, Sync, Deci
Select the type of modulation that will occur between the
oscillators. Since OSC2 will be modulated (i.e., it will be
the slave), the results of the modulation will be output from
OSC2.
For either of the types of oscillator modulation, using a
motion sequence etc. to change the pitch of OSC2 will pro-
duce timbral changes.

When OSC Mod is off, the oscillators will not modulate each
other.
By using OSC2 Pitch Ofs to create a slight difference in pitch
between the oscillators, you can produce a spacious detune
effect. Setting a one-octave difference in pitch is effective
when you wish to create thick synth-bass sounds etc.

Ring Mod
This type of modulation generates a frequency consisting
of the sum and difference of the OSC1 and OSC2 frequen-
cies. When you move the OSC2 pitch offset knob the tim-
bre will change, producing metallic sounds or sound effects.
The modulated sound will be output from OSC2
The tone and volume of Ring Modulation may vary
depending on the phase difference between OSC1
and OSC2.

Sync
This type of modulation forcibly resets the OSC2 waveform
by synchronizing its pitch to the pitch of OSC1. Moving
the pitch of OSC2 will produce the popular "sync lead"
sound. The modulated sound will be output from OSC2.
Differences in the OSC1 waveform will not affect the out-
put of OSC2.

Decimater
This type of modulation reproduces the OSC1 waveform
at the sampling frequency of OSC2. The digitized OSC1
waveform will be output from OSC2. This is effective when
creating electric bass sounds etc.
If OSC1 is a square wave, Decimator will have little
effect.
When OSC Mod is set to Decimator, the basic wave-
form of OSC2 will be ignored.

The filter processes the sound produced by the oscillator to make
it less bright, etc.

Cutoff 0 Hz ... 20,000 Hz
Set the cutoff frequency of the low-pass filter. Overtones
higher than the cutoff frequency will be cut, making the
sound more mellow.
If Cutoff and EG Int are set to 0, you will hear virtu-
ally no sound.
