This algorithm simulates the acoustic ef-
fects of multi-stringed instruments. A series
of resonators tuned to a chromatic scale are
provided with controls for tuning and damp-
ing.
Suggested applications for this algorithm
include enhancing synthetic instruments
and amplified strings. Caution is advised in
using this algorithm with voice (especially
spoken) and percussion.
The Tuning parameter tunes all 12 reso-
nators over a range of more than an octave
to match the tuning of your instrument.
Predelay spaces out the onset of the resona-
tors to produce a strumming effect. Low
Frequency Cutoff filters the input audio to
reduce boominess for low tunings. Reso-
nance Feedback affects the lowest pitch
resonator. The other resonators are set
based on this value and the value of Slope.
Shimmer sets the
period of resonator
detuning. This parameter is factory preset to
change one resonator every 0.5 seconds.
Richness sets the
amount of periodic
detuning. Slope controls timbre.
This algorithm was used to create Preset
