oscillator_multi

Configure a region to use more than one oscillator.

Assuming oscillator_mode=0:

• If the value is 1, the region operates normally, in single oscillator mode.
• If the value is 2, the region operates in ring modulation mode.
• If between 3 and 9, this defines a unison, with the value being the number of oscillators. In this case, oscillator_detune must also be set to indicate the spread between the oscillators.

Cakewalk unison

Let m be the number of oscillators defined by oscillator_multi, and d the detune value defined by oscillator_detune.

The array of m oscillators is tuned by multiplying d for each oscillator by its coefficient.

The oscillators sum into left and right channels with declining linear gain, opposite for each channel. With i the number of the oscillator (starting at 1), the left gain is (i-1)/(m-1), and the right gain is 1-((i-1)/(m-1)).
