Protected Functions

bool get_audio_node_index(fx_audio_node *node, uint8_t *local_node_index)

Looks up the index of a given node in the node stack for this effect.

Return

True if found, false if not

Parameters

• node: The node to look up

• node_index: The node index that was looked up (output)

bool get_control_node_index(fx_control_node *node, uint8_t *local_node_index)

uint16_t *serialize_params(uint16_t *serialized_params, uint16_t *size)

bool float_param_updated(float *param, float *param_last, float threshold)

Checks to see if a float parameter has been updated.

This function also applies hysteresis

Return

True if updated, false if not

Parameters

• param_last: The parameter last

bool bool_param_updated(bool *param, bool *param_last)

Checks to see if a bool parameter has been updated.

Return

True if updated, false if not

Parameters

• param: The parameter

• param_last: The parameter last
