Functions

beginAudioProcessing

void beginAudioProcessing()

Switch on the plugin. Call it before processing.

closeUI

void closeUI()

Closes the editor.

endAudioProcessing

void endAudioProcessing()

Switch off the plugin. Call it after processing.

getCurrentProgram

int getCurrentProgram()

Gets current "program" index. Note: not all presets are exposed to the host. In many plug-ins they aren't.

getEffectName

const(char)[] getEffectName()

ditto Lifetime of return value is same as IPluginHost.

getLatencySamples

int getLatencySamples()

Get current plug-in latency in samples. Because of VST2 limitations, this number of only valid between a beginAudioProcessing and endAudioProcessing call, and won't move while processing.

getParameter

float getParameter(int paramIndex)

getParameterCount

int getParameterCount()

getParameterName

const(char)[] getParameterName(int paramIndex)

getProductString

const(char)[] getProductString()

Get plugin information. Lifetime of return value is same as IPluginHost.

getTailSizeInSeconds

double getTailSizeInSeconds()

Get tail size in seconds. Precise semantics TBD.

getUISize

int[2] getUISize()

Gets the UI size.

getVendorString

const(char)[] getVendorString()

ditto Lifetime of return value is same as IPluginHost.

loadPreset

void loadPreset(int presetIndex)

Loads a preset.

openUI

void openUI(void* windowHandle)

Opens the editor window. On Windows, pass a HWND On Mac, a NSView

processAudioFloat

void processAudioFloat(float** inputs, float** ouputs, int samples)

Process some audio. setSampleRate and setMaxBufferSize must be called before use. samples must <= the maximum buffer size asked in

restoreState

bool restoreState(const(ubyte)[] chunk)

Restore state of the plugin, saved with saveState.

saveState

const(ubyte)[] saveState()

Serialize state of the plugin, to restore with restoreState.

setIO

bool setIO(int numInputs, int numOutputs)

Sets I/O arrangement (simple right now).

setMaxBufferSize

void setMaxBufferSize(int samples)

Sets the maximum buffer size

setParameter

void setParameter(int paramIndex, float normalizedValue)

Sets a parameter's value.

setSampleRate

void setSampleRate(float sampleRate)

Sets the desired sampleRate
