Selecting an Oscillator
Choose the desired oscillator with the button. The LED of
the corresponding Oscillator will light up.
Oscillator Parameter Controls
Shape off / Pulse / Saw / Triangle / Sine / Alt 1 /
Alt 2 / Wavetables / Samples
Sets the type of waveform to be generated by the
Oscillator. The parameter is called Shape instead of
“waveform”, because it doesn’t necessarily set only one
waveform, but sets a specific oscillator model that could
produce a number of waveforms depending on other
settings. A good example for this behaviour is the Pulse
shape. However, the term “waveform” is used
interchangeably throughout the manual. The following
shapes are currently available:
• off disables the selected oscillator for the purpose of
increasing Polyphony.
• Pulse selects the pulse waveform. A pulse waveform
with a pulse width of 50% has only the odd
harmonics of the fundamental frequency present.
This waveform produces a hollow / metallic sound.
If the Pulse waveform is selected, the parameters
Pulsewidth
and PWM are used to change the
pulsewidth of the waveform. Furthermore, the
modulation destinations O1PW, O2PW or O3PW
gain functionality, depending on which oscillator is
set to Pulse. The parameter Brilliance is for adding
more brilliance to the Pulse wave.
• Saw selects the sawtooth waveform. A Sawtooth
wave has all the harmonics of the fundamental
frequency in descending magnitude. It doesn’t have
any further parameters. This waveform is pleasing to
the ear. The parameter Brilliance is for adding more
brilliance to the Saw wave.
• Triangle selects the triangular waveform. The triangle
mainly consists of the odd harmonics with very low
magnitudes. It doesn’t have any further parameters.
• Sine consists of the fundamental frequency only. It
has no harmonics at all. It doesn’t have any further
parameter.
