8.2.2.6 Dual Sine (Oscillator 1)


The Dual Sine waveform of Oscillator 1 is a combination of two Sine waves (Sine wave 1 & 2) while Sine wave 2 is pitched 1 octave higher than Sine wave 1.


Dual Sine (normal mode):

In normal mode (non-FM) the two Sine waves are simply mixed to one signal while the Shape fader controls the level of Sine wave 2.

Shape in normal Dual Sine mode:

Controls the level of Sine wave 2 (the 1 Octave higher one).

Dual Sine FM:

Instead of the Sync switch (which the other waveforms provide), the Dual Sine waveform provides an FM mode. With Dual Sine FM enabled you have a 2 operator FM engine (as a single Oscillator waveform) with Sine wave 1 as Carrier and Sine wave 2 as Modulator. Note that if FM is enabled, both Sine waves are at the same pitch (rather than in normal Dual Sine mode one Octave separated).

With FM enabled you can choose from 5 different FM algorithms: Phase Modulation (like in DX7)

Logarithmic +

Logarithmic +/- Linear +
