Dual Mode Parameters
The parameters specific to Dual mode are found in the Wave 2 section, and the Balance
slider to the right.
 Semi parameter: Adjusts the tuning of the second oscillator (Wave 2) in semitone steps.
 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.
 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.
 Ratio c(oarse) parameter: Adjusts the coarse frequency ratio of the second oscillator
in relation to the first oscillator.
 Ratio f(ine) parameter: Adjusts the fine frequency ratio of the second oscillator in
relation to the first oscillator.
 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.
