closeUI

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.

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)

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)
