class: mStringInstrument
Karplus-Strong string instrument
Description
mStringInstrument is a polyphonic instrument that generates sound through a basic physical model of a plucked vibrating strign. It inherits all functions from the mInstrument parent class and adds the following functionality.
Template Parameters
template <uint16_t mPOLYPHONY = 4>mPOLYPHONY: number of voices the instrument can play simultaneously
Class Methods
Constructor
mStringInstrument(float lowest_freq, uint_8 *midi_table_name = NULL>lowest_freq: lowest frequency (in Hz) that you want the instrument to be able to play. Setting lower frequencies requires a longer internal delay line per voice, increasing memory requirements.
midi_table_name: (OPTIONAL) table of MIDI data for the instrument to play.
int32_t next()Calculates a sample of output. Nominally a 16-bit signal level. MUST BE CALLED IN updateAudio()
void setLoopGain(float loop_gain)Sets feedback gain within physical model (0 to 1.0). Higher values yield notes with a high sustain.
