Member Function Documentation

next()

template<unsigned int CONTROL_UPDATE_RATE>

Q16n16 Portamento< CONTROL_UPDATE_RATE >::next ( )

inline

Use this in updateControl() to provide a frequency to the oscillator it's controlling.

For example: myOscil.setFreq_Q16n16(myPortamento.next());

Returns

a Q16n16 fractional frequency value, progressing smoothly between successive notes.

setTime()

template<unsigned int CONTROL_UPDATE_RATE>

void Portamento< CONTROL_UPDATE_RATE >::setTime ( unsigned int  milliseconds )

inline

Set how long it will take to slide from note to note, in milliseconds.

Parameters

milliseconds

start() [1/2]

template<unsigned int CONTROL_UPDATE_RATE>

void Portamento< CONTROL_UPDATE_RATE >::start ( uint8_t  note )

inline

Call this at note-on, it initialises the portamento.

Parameters

note	a midi note number, a whole number.

Definition at line 47 of file Portamento.h.

start() [2/2]

template<unsigned int CONTROL_UPDATE_RATE>

void Portamento< CONTROL_UPDATE_RATE >::start ( Q16n16  note )

inline

Call this at note-on, it initialises the portamento.

Parameters

note	a midi note number in Q16n16 fractional format. This is useful for non-whole note or detuned values.
