Reference
Basic waveforms used as Operators contain harmonics, with the exception of “Sine.” A sine wave contains
its fundamental frequency with no additional harmonics. Therefore, when “Form” is set to any waveform
other than “Sine,” you can adjust harmonics and the peak of each formant, depending on the Waveform
Type by determining the related parameters. Below are the basic waveforms and the characteristic
parameters.
The larger the “Skirt” value, the more harmonics the wave contains.
The larger “Resonance” value, the higher frequency the center frequency is moved.
• Resonance=0: The Center frequency is the basic wave
• Resonance=99: The Center frequency is the 100th harmonic
Key On Reset (Oscillator Key On Reset)
Determines whether or not the oscillation of the Operator is reset each time a note is pressed.
Settings:
Off, On
Pitch/Vel (Pitch Velocity Sensitivity)
Determines how the pitch of the selected Operator responds to velocity. This is available only when “Freq
Mode” is set to “Fixed.”
Settings:
-7 – +7
Positive values:
The harder you play the keyboard, the more the pitch rises.
Negative values:
The harder you play the keyboard, the more the pitch falls.
0:
No change in pitch.
Freq Mode (Oscillator Frequency Mode)
Determines the settings for the Output Pitch of the Operator.
Settings:
Ratio, Fixed
Ratio:
Determines the Output Pitch by detecting the note you play on the keyboard.
Fixed:
Specifies the Pitch by setting “Coarse” and “Fine.”
