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

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.

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.

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.

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.

template<typename T>

T*& LV2::Voice::p

(

uint32_t

port

)

[inline, protected]

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

float*& LV2::Voice::p

(

uint32_t

port

)

[inline, protected]

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