Detailed Description

A base class for synth voices, to be used with the Synth template class. You don't have to make your voice classes inherit this one, but it makes some things easier.

Member Function Documentation

get_key()

unsigned char LV2::Voice::get_key ( ) const

inline

Return the MIDI key that the voice is currently playing. LV2::INVALID_KEY means that the voice is not active and could be used to play a new note.

Referenced by LV2::Synth< V, D, Ext1, Ext2, Ext3, Ext4, Ext5, Ext6, Ext7 >::find_free_voice(), and LV2::Synth< V, D, Ext1, Ext2, Ext3, Ext4, Ext5, Ext6, Ext7 >::handle_midi().

off()

void LV2::Voice::off ( unsigned char  velocity )

inline

Turn the voice off. This default implementation does nothing, you probably want to override it.

Parameters

velocity

The MIDI velocity for the Note Off event.

on()

void LV2::Voice::on ( unsigned char  key, unsigned char  velocity  )

inline

Turn the voice on. This default implementation does nothing, you probably want to override it.

If key is LV2::INVALID_KEY the voice should go silent as fast at possible (the synth may use this when it receives an All Sound Off event).

Parameters

key	The MIDI key for the note that the voice should play.
velocity	The MIDI velocity for the Note On event.

p() [1/2]

template<typename T >

T*& LV2::Voice::p ( uint32_t  port )

inlineprotected

Same as Plugin::p() - returns the buffer for the given port.

Referenced by LV2::Synth< V, D, Ext1, Ext2, Ext3, Ext4, Ext5, Ext6, Ext7 >::run().

p() [2/2]

float*& LV2::Voice::p ( uint32_t  port )

inlineprotected

Same as Plugin::p() - returns the buffer for the given port.

render()

void LV2::Voice::render ( uint32_t  from, uint32_t  to  )

inline

Render audio for this voice to the output buffers, from sample from to sample to. The buffers may already contain audio from other voices, so use += instead of = when writing to it. This default implementation does nothing, you probably want to override it.
