tool, we’ve provided a DRIVE knob that boosts the signal before it enters the filter. Turn this knob up and
you’ll hear the signal become louder and more distorted, in a good way.
The Modulation Source (MOD SRC) knobs control how much the filter’s frequency is affected (i.e. modulated)
by the LFO and envelope follower. Turning these knobs clockwise from their center position will cause the LFO
and/or envelope follower to increase the filter’s frequency, and turning the knobs anti-clockwise will have the
opposite effect. Note that there are combinations of settings in which the modulators have no audible effect.
For instance, if you turn the FREQUENCY knob all the way up, you won’t hear anything if you turn the MOD
SRC knobs above the 12 o’clock position because the modulators can’t raise the filter frequency any higher
than its highest setting. On the other hand, if you turn the MOD SRC knobs below the 12 o’clock position, you
will hear the modulators lowering the filter’s frequency.
LFO
Mangleverb sports a low-frequency oscillator (LFO) for generating periodic
signals. These signals can control the filter and/or VCA, creating synthesizer-like
tonal changes, tremolo and gating effects, etc. The LFO can be locked to the
tempo of your host program for creating rhythmic effects that fit with the groove
of your music, or can run freely and independently.
The RATE knob determines how fast the output of the LFO varies over time. If
the SYNC switch is not turned on, the LFO’s rate can be varied from one cycle
every 100 seconds (that is 0.01 cycles per second, abbreviated 0.01 Hz) to 100
cycles every second (100 Hz).
If the SYNC switch is turned on, the LFO’s rate is determined by the tempo of
your music as reported by your host sequencer. A value of 1/1 represents a
whole note, a value of 1/8 represents an eighth note, and so on. Dotted notes,
which have a duration equal to one and a half times a regular note, are shown
with a period in the RATE knob’s value display. For example “1/4.” is displayed
to indicate a dotted quarter note, which has a duration of a quarter note plus an
eighth note. Triplets, which are groups of three notes that have the same duration as two regular notes, are
shown with a T. “1/16T” represents a duration equal to 2/3 that of a sixteenth note.
The WAVEFORM switch and SHAPE knob together control how the LFO’s output varies over time. The
WAVEFORM switch lets you choose one of four waveforms, with triangular, rectangular, sinusoidal, and
