THE RESONANT CHORD
ALGORITHMS
RES1>PLATE AND RES2>PLATE
The Resonant Chord effects use impulsive energy
at the inputs to excite six resonant voices
(notes). The level, pitch, duration, and high-
frequency cutoff of the overtones for each voice
are separately controllable. Each voice can be
panned independently. The voices resonate to
some degree with any input, but the most
effective excitation contains all frequencies, like
percussion. Other instruments may give a
quality of tonal ambience in which certain notes
rise ethereally from the background. The output
of the resonator is then fed into a stereo plate
reverb effect.
The two algorithms differ in the way pitches are
assigned to the resonators. In Res1>Plate, pitches
are assigned to the six voices chromatically, in a
round-robin. For example, if MIDI note numbers
are used to assign pitch, the resonators will
constantly be re-tuned to the pitches of the last
six MIDI notes received. (This can produce an
effect similar to playing a piano with the sustain
pedal depressed.) In Res2>Plate, pitches are
assigned to the six resonators diatonically,
harmonized with the key, scale, and root of your
choice. If MIDI note numbers are used to assign
pitch, the resonators will constantly be re-tuned
to harmonize with the incoming notes.
