Lfo Shapes & Envelopes - Electro-Harmonix MOD 11 Manual

Different LFO (low frequency oscillator) shapes dramatically change the
feel and sound of a given modulation. In TREM, VIBR, FLANGE, TZF,
PHASE, and FILT types, you can adjust the LFO shape with a secondary
control (turning the RATE knob when in secondary mode, see page 7). In
FLANGE, PHASE, and FILT types, you can also set this "LFO shape" to your
playing envelope, where the sound of the effect will be directly related to
the volume
SHAPES
– LFO SHAPES & ENVELOPES –
of the input
Sine: A sine wave LFO is the most common
LFO shape and the default in every mod type
in the MOD 11. The modulated parameter
smoothly moves between its minimum and
maximum in a fluid, seamless way.
Triangle: An extra option just in the TREM
type, the triangle wave is very similar to the
sine, but with a slightly different feel as the
parameter change is more linear.
Rising Sawtooth: The modulated parameter
smoothly rises from its minimum to its
maximum, before sharply resetting at its
minimum. Can be used to create reverse or
side-chain like effects.
Falling Sawtooth: The opposite of the rising
sawtooth, the modulated parameter
smoothly falls from maximum to minimum,
before sharply resetting at its maximum.
Can be used for rhythmic effects.
Square: The modulated parameter jumps
directly between minimum and maximum,
with no smooth transitions. Can be used to
create choppy or robotic effects.
