ar shaker kamp, kfreq, kbeans, kdamp, ktimes[, idecay]
Audio output is a tone related to the shaking of a maraca or similar gourd instrument. The method is a physically inspired model developed from Perry Cook, but re-coded for Csound.
idecay - If present indicates for how long at the end of the note the shaker is to be damped. The default value is zero.
A note is played on a maraca-like instrument, with the arguments as below.
kamp – Amplitude of note.
kfreq – Frequency of note played.
kbeans - The number of beans in the gourd. A value of 8 seems suitable,
kdamp -- The damping value of the shaker. Values of 0.98 to 1 seems suitable, with 0.99 a reasonable default.
ktimes -- Number of times shaken.
The argument knum was redundant, so was removed in version 3.49.
