CHAPTER 21. LIVE AUDIO EFFECT REFERENCE 295
Enabling Off Decay causes MIDI note off messages to mute the resonance. The slider below
the switch determines the extent to which MIDI note off messages mute the resonance. At
0%, note offs are ignored, and the decay time is based only on the value of the Decay
parameter, which is located under the Resonance Type selector. This is similar to how
real-world mallet instruments such as a marimbas and glockenspiels behave. At 100%, the
resonance is muted immediately at note off, regardless of the Decay time.
You can hide or show the Sidechain parameters by toggling the button in Corpus's title
bar. This button will light up if the sidechain is active.
Corpus contains a Low Frequency Oscillator (LFO) to modulate the resonant frequency. The
Amount control sets how much the LFO affects the frequency.
The Rate control species the LFO speed. It can be set in terms of Hertz, or synced to the
song tempo, allowing for controlled rhythmic modulation.
Available LFO waveform shapes are sine (creates smooth modulations with rounded peaks
and valleys), square, triangle, sawtooth up, sawtooth down and two types of noise (stepped
and smooth).
Although only one set of LFO controls is visible, there are actually two LFOs, one for each
stereo channel. The Phase and Spin controls dene the relationship between these two
LFOs.
Phase (available only when the LFOs are synced to song tempo) keeps both LFOs at the
same frequency, but can set the two LFO waveforms out of phase with each other, creating
stereo movement. Set to 180, the LFO outputs are 180 degrees apart, so that when one
LFO reaches its peak, the other is at its minimum. With Phase set to 360 or 0 the two
LFOs run in sync.
Spin (only available when the LFOs are in Hertz mode) detunes the two LFO speeds relative
to each other. Each stereo channel is modulated at a different frequency, as determined by
the Spin amount.
For the noise wavefor ms, the Phase and Spin controls are not relevant and do not affect the
sound.
Spread detunes the two resonators in relation to each other. Positive values raise the pitch
of the left resonator while lowering the pitch of the right one, while negative values do the
opposite. At 0%, the resonators are tuned the same.
