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.
- 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.
