SUPPORT INFORMATION
Pulse Width (PW): The pulse width marks the duration a pulse signal is
'on'. It is commonly measured in percentages of a duty cycle. A duty cycle
of 50% produces a square wave, meaning that the pulse signal is on for as
long as it's off per duty cycle. Changing the on/off ratio alters the harmonic
content, and thus changes the timbre. The sound of a pulse wave that
has a duty cycle of more or less than 50% is thinner than that of a square
wave and bears a nasal character. At a duty cycle of 0% or 100% there
is no audible sound, as there is no change in amplitude that constitutes
oscillation.
Pulse Width Modulation (PWM): Pulse width modulation affects how the
pulse width changes over time while you are holding a note. The pulse
width can be modulated by a modulation source such as an LFO or an
envelope, resulting in a thicker or more harmonically interesting sound.
Resonance: This filter parameter emphasised the frequencies around
the cutoff frequency. The Super 6's low-pass filter can be driven into self-
oscillation if you set the resonance to its highest value. In this case, the
filter generates a pitch determined by the cutoff frequency and a timbre
that sounds like a sine wave.
Sequencer: A sequencer is a modulation source that acts like a recording
and playback device, sending control signals to a variety of parameters
per step, the smallest unit of a sequence. The Super 6's sequencer allows
recording of up to 64 steps and was primarily designed for recording and
editing note events.
Split Point: The split point is a note on the Super 6's keyboard relative to
which the audio signals of DDS 1 and DDS 2 or DDS 1 and an external
audio signal are be crossfaded if you enable X-Fade mode.
Sub-Oscillator: A sub-oscillator is an oscillator with a fixed waveform
that is an octave or more below the frequency of the oscillator to which it
is tied. In the case of the Super 6, the enabled sub-oscillator replaces the
audio signal from DDS 2. Its waveform is a square wave pitch-locked one
octave below the frequency of DDS 1.
Super Mode: Super mode is a unique feature that takes advantage of the
Super 6's stereo signal path. In both available super modes, DDS 1 can be
dynamically de-phased in the stereo field, resulting in a thick, wide sound
from a single oscillator.
Super Wave Modulation (SWM): When super mode is engaged, super
wave modulation determines how much modulation depth is applied to
the DDS 1 detune spread modulation.
Swing: Swing is a rhythmic variation in which the first and second
consecutive notes of a two-part beat pattern are alternately lengthened
and shortened. The Super 6 offers five different swing settings when
you engage arpeggiator or sequencer playback, ranging from none to
pronounced. Use swing to make your pattern 'bounce'.
