Creating sounds
fig.PWFB-knob
This knob is effective only if specific waveforms are selected by the WAVE buttons (p. 28).
When (asymmetrical square (pulse) wave) is selected
The knob specifies the width of the high portion of the waveform (i.e., the pulse width) as a percentage of the
entire cycle.
• Turning the knob toward the left narrows the pulse width, approaching a square wave ( , pulse width =
50%).
• Turning the knob toward the right broadens the pulse width, producing a distinctive sound.
When FB OSC is selected
The knob specifies the amount of output sound that is to be returned (fed back) to the input.
Turning the knob toward the right increases the feedback, producing more overtones and making the sound more
aggressive.
When SUPER SAW is selected
The knob specifies the amount of pitch spread between the seven sawtooth waves layered within a single
oscillator. Turning the knob toward the right will increase the pitch spread.
(In this case, the DETUNE knob will adjust all seven sawtooth waves by the same pitch amount.)
fig.INTERVAL-buttons
-OCT (minus octave) button
This button lowers the OSC 2 pitch one octave below that of OSC 1.
Pressing a single key will produce a rich sound, as though you had also played another key one octave below.
5th button
If you press this button, the OSC 2 pitch will be seven semitones (a perfect fifth) higher than OSC 1.
Playing a single key will produce a fifth chord, creating a heavy sound.
* If you press the -OCT button and the 5th button simultaneously, the OSC 2 pitch will be the same as the OSC 1 pitch.
* Parameters other than pitch will not change.
