synthesis signal.
Dual Mode Parameters
The parameters specific to Dual mode are found in the Wave 2 section, and the Balance
slider to the right.
• The Semi parameter adjusts the tuning of the second oscillator (Wave 2) in semitone
steps. Adjustment is made by using the mouse as a slider directly on the numerical
field. Its range: ±24, or up/down two octaves.
• The Detune parameter fine-tunes Wave 1 and Wave 2 in cents. 100 cents equals a
semitone step. Doing so will detune Wave 1 in conjunction with Wave 2 around the
tuning zero point. The range is ±50 cents, or up/down half a semitone. Adjustment is
made by using the mouse as a slider directly on the numerical field.
• The Balance slider allows you to blend the two oscillator signals (Wave 1 and Wave 2).
FM Mode Parameters
The parameters specific to the FM mode are found in the Wave 2 section, and the FM
Int slider to the right.
• The Ratio c(oarse) parameter adjusts the coarse frequency ratio of the second
oscillator in relation to the first oscillator. Adjustment is made by using the mouse as
a slider directly on the numerical field. Range: 0–32.
• The Ratio f(ine) parameter adjusts the fine frequency ratio of the second oscillator in
relation to the first oscillator. The range is 0–99. Adjustment is made by using the
mouse as a slider directly on the numerical field
• The FM Int slider determines the intensity of Wave 1’s sine wave modulation by Wave
2. Higher FM Int settings will result in a more complex waveform with more
overtones.
When combined, the Ratio and FM Int parameters form the resulting complex FM
waveform, thus defining the harmonic content.
