Phaser
A Phaser is a combination of several "allpass" filters
working in parallel. This generates an effect with equally
spaced frequency peaks or troughs. The result is a strongly
colorized signal with a “spacy” character.
w
A Mix setting of 48 to 96 produces the strongest
effect because both the unaffected signal and the
processed signal are mixed together.
Speed 0…127
Sets the LFO speed of the Phaser effect.
Depth 0…127
Sets the modulation depth of the Phaser effect.
Center 0…127
Controls the basic delay length of the allpass filters. Lower
settings produce a high pitched Phaser effect while higher
settings enable the Phaser to cover deeper frequencies.
Spacing 0…127
Controls the relative frequencies of the allpass filters. A
setting of 0 produces a classic phaser, while higher
settings spread out the frequencies of the allpass filters.
Feedback 0…127
Controls the feedback amount of the delay signal.
Polarity positive / negative
Determines whether the feedback signal is fed back into
the Phaser as is, or is inverted beforehand.
Overdrive
The Overdrive effect distorts the input signal by
amplifying it drastically and clipping the resulting signal
to a certain output level. The difference between this
Overdrive effect and the Drive parameter of the Filter
sections is that Drive affects one single voice, while this
effect type distorts the summed output of the whole
instrument. Therefore, the resulting effect is different as
soon as you play more than one note and you should
consider which is best suited to a particular sound
