behaviour is the Pulse shape. However, the term “waveform” is used interchangeably throughout the
manual. The following shapes are currently available:
Pulse
(variable Pulse Width)
Sawtooth Triangle Sine
• Pulse selects the pulse waveform. A pulse waveform with a pulse width of 50% only has
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 .
• 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.
• Tri selects the triangular waveform. The triangle mainly consists of the odd harmonics with
very low magnitudes. It doesn’t have any further parameters.
• The Sine waveform consists of the fundamental frequency only. It has no harmonics at all.
It doesn’t have any further parameters.
• Alt1 and Alt2 are wavetable generators. Both can create a wavetable with 128 waves
each. Please refer the chapter "Wavetable synthesis". When Alt1 or Alt2 are selected, the
knobs
Pulsewidth
and
PWM
serve for selecting the startpoint of the waves. Furthermore
the modulation sources 01PW and 02PW are active subject to which Oscillator is set to
Alt . In the Oscillator Edit Menu you additionally have Suboscillators at your disposal
(please read also „Suboscillators“ in the chapter „Oscillator Edit Menu“ on page 78 about
this). Please note that the Wavetables are only available for Oscillators 1 and 2.

The Pulse shape can be used to create unusual synthesizer sounds and oboe like sounds.

The Saw shape can be used for basses, leads, brass and string sounds.

The Tri shape can be used for flute sounds or soft pads.

The Sine shape can be used to produce basses and electric organ sounds.

The Sine shape is also perfectly suited for ring modulation or as FM Source .

Alt1/are perfect for very vivid sounds.

The tips shown in this place of course are only recommendations. The variety of tones of all
Waveforms in the Q are nearly inexhaustible.
Pulsewidth
0…127
Sets the pulse width of the Pulse waveform. The value 0 is equivalent to a pulse ratio of <1%, the
value 127 is equivalent to 50%. You determine the startpoint of the wavetable at Alt1 or Alt2 with the
Pulsewidth knob, at which 0 selects the first of 128 Waveforms. If you select any waveform other
