INPUT
OUTPUT

Member Function Documentation

◆ setVoltage()

void rack::engine::Port::setVoltage	(	float	voltage,
		uint8_t	channel = 0 )

inline

Sets the voltage of the given channel.

◆ getVoltage()

float rack::engine::Port::getVoltage ( uint8_t channel = 0 )

inline

Returns the voltage of the given channel.

Because of proper bookkeeping, all channels higher than the input port's number of channels should be 0V.

◆ getPolyVoltage()

float rack::engine::Port::getPolyVoltage ( uint8_t channel )

inline

Returns the given channel's voltage if the port is polyphonic, otherwise returns the first voltage (channel 0).

◆ getNormalVoltage()

float rack::engine::Port::getNormalVoltage	(	float	normalVoltage,
		uint8_t	channel = 0 )

inline

Returns the voltage if a cable is connected, otherwise returns the given normal voltage.

◆ getNormalPolyVoltage()

float rack::engine::Port::getNormalPolyVoltage	(	float	normalVoltage,
		uint8_t	channel )

inline

◆ getVoltages()

float * rack::engine::Port::getVoltages ( uint8_t firstChannel = 0 )

inline

Returns a pointer to the array of voltages beginning with firstChannel.

The pointer can be used for reading and writing.

◆ readVoltages()

void rack::engine::Port::readVoltages ( float * v )

inline

Copies the port's voltages to an array of size at least channels.

◆ writeVoltages()

void rack::engine::Port::writeVoltages ( const float * v )

inline

Copies an array of size at least channels to the port's voltages.

Remember to set the number of channels before calling this method.

◆ clearVoltages()

void rack::engine::Port::clearVoltages ( )

inline

Sets all voltages to 0.

◆ getVoltageSum()

float rack::engine::Port::getVoltageSum ( )

inline

Returns the sum of all voltages.

◆ getVoltageRMS()

float rack::engine::Port::getVoltageRMS ( )

inline

Returns the root-mean-square of all voltages.

Uses sqrt() which is slow, so use a custom approximation if calling frequently.

◆ getVoltageSimd()

template<typename T>

T rack::engine::Port::getVoltageSimd ( uint8_t firstChannel )

inline

◆ getPolyVoltageSimd()

template<typename T>

T rack::engine::Port::getPolyVoltageSimd ( uint8_t firstChannel )

inline

◆ getNormalVoltageSimd()

template<typename T>

T rack::engine::Port::getNormalVoltageSimd	(	T	normalVoltage,
		uint8_t	firstChannel )

inline

◆ getNormalPolyVoltageSimd()

template<typename T>

T rack::engine::Port::getNormalPolyVoltageSimd	(	T	normalVoltage,
		uint8_t	firstChannel )

inline

◆ setVoltageSimd()

template<typename T>

void rack::engine::Port::setVoltageSimd	(	T	voltage,
		uint8_t	firstChannel )

inline

◆ setChannels()

void rack::engine::Port::setChannels ( uint8_t channels )

inline

Sets the number of polyphony channels.

Also clears voltages of higher channels. If disconnected, this does nothing (channels remains 0). If 0 is given, channels is set to 1 but all voltages are cleared.

◆ getChannels()

int rack::engine::Port::getChannels ( )

inline

Returns the number of channels.

If the port is disconnected, it has 0 channels.

◆ isConnected()

bool rack::engine::Port::isConnected ( )

inline

Returns whether a cable is connected to the Port.

You can use this for skipping code that generates output voltages.

◆ isMonophonic()

bool rack::engine::Port::isMonophonic ( )

inline

Returns whether the cable exists and has 1 channel.

◆ isPolyphonic()

bool rack::engine::Port::isPolyphonic ( )

inline

Returns whether the cable exists and has more than 1 channel.

◆ normalize()

DEPRECATED float rack::engine::Port::normalize ( float normalVoltage )

inline

Use getNormalVoltage() instead.

"Normal" voltage is the correct term, not "normalized" voltage.

Member Data Documentation

◆ voltages

float rack::engine::Port::voltages[PORT_MAX_CHANNELS] = {}

Unstable API.

Use getVoltage() and setVoltage() instead.

◆ value

float rack::engine::Port::value

DEPRECATED.

Unstable API. Use getVoltage() and setVoltage() instead.

◆ [union]

union { ... } rack::engine::Port

Voltage of the port.

◆ channels

uint8_t rack::engine::Port::channels = 0

Number of polyphonic channels.

DEPRECATED. Unstable API. Use set/getChannels() instead. May be 0 to PORT_MAX_CHANNELS. 0 channels means disconnected.

◆ active

uint8_t rack::engine::Port::active

DEPRECATED.

Unstable API. Use isConnected() instead.

◆ [union]

union { ... } rack::engine::Port

◆ plugLights

Light rack::engine::Port::plugLights[3]

For rendering plug lights on cables.

Green for positive, red for negative, and blue for polyphonic.
