stk::Instrmnt::Instrmnt
Instrmnt(void)
Class constructor.
Definition Instrmnt.h:23
stk::Mandolin::setBodySize
void setBodySize(StkFloat size)
Set the body size (a value of 1.0 produces the "default" size).
stk::Mandolin::clear
void clear(void)
Reset and clear all internal state.
stk::Mandolin::pluck
void pluck(StkFloat amplitude)
Pluck the strings with the given amplitude (0.0 - 1.0) using the current frequency.
stk::Mandolin::noteOff
void noteOff(StkFloat amplitude)
Stop a note with the given amplitude (speed of decay).
stk::Mandolin::Mandolin
Mandolin(StkFloat lowestFrequency)
Class constructor, taking the lowest desired playing frequency.
stk::Mandolin::pluck
void pluck(StkFloat amplitude, StkFloat position)
Pluck the strings with the given amplitude (0.0 - 1.0) and position (0.0 - 1.0).
stk::Mandolin::setPluckPosition
void setPluckPosition(StkFloat position)
Set the pluck or "excitation" position along the string (0.0 - 1.0).
stk::Mandolin::noteOn
void noteOn(StkFloat frequency, StkFloat amplitude)
Start a note with the given frequency and amplitude (0.0 - 1.0).
