Osc 3
This is where you will find the controls relating to oscillator 3.
> OSC MODE
This allows you to choose from a selection of 66 waveshapes, including
saw, pulse, sine and triangle, including 62 additional spectral waves (the same selection
available to osc 1 and 2). There is also an additional ‘Slave’ mode, in which osc 3 takes it’s
characteristics from osc 2. No osc 3 parameters will have any effect in this mode, which was
designed as a simple way to add more depth to the sound.
Since most sounds only require 2
oscillators, osc 3 is optional, hence the default setting is ‘Off’. It also takes more calculating
power, and as such will result in a reduction in polyphony when activated
.
> SEMITONE*
This adjusts the pitch of osc 3 within a range of 4 octaves (48 semitones) above or below
middle C. If osc 1 and 2 are both set to Semitone = 0, try setting osc 3 Semitone to +7 (per-
fect 5
th
) – a technique used in many classic lead sounds.
> DETUNE*
This offsets the pitch of osc 3 relative to osc 1 and 2. This works in the opposite direction to
osc 2 Detune, so the higher the value, the lower the pitch.
Use this to add more warmth and subtle movement to the sound.
NOTE:
Like Osc2 Detune, this parameter is affected by keyfollow (MIDI note number) for a
more musical result.
NOTE:
*This parameter has no effect if Osc Mode is set to Off.
