Detailed Description

A TrackProcessor is a processor that is used as the first entry point when processing a track.

Definition at line 43 of file track_processor.h.

Field Documentation

◆ cc_mappings

MidiMappings* TrackProcessor::cc_mappings

Mappings to each CC port.

Definition at line 107 of file track_processor.h.

◆ channel_pressure

Port* TrackProcessor::channel_pressure[16]

Channel pressure (aftertouch).

This message is different from polyphonic after-touch - sends the single greatest pressure value (of all the current depressed keys).

Definition at line 132 of file track_processor.h.

◆ input_gain

Port* TrackProcessor::input_gain

Input gain, if audio.

Definition at line 54 of file track_processor.h.

◆ l_port_db

float TrackProcessor::l_port_db

Current dBFS after processing each output port.

Transient variables only used by the GUI.

Definition at line 141 of file track_processor.h.

◆ magic

int TrackProcessor::magic

Definition at line 163 of file track_processor.h.

◆ midi_cc

Port* TrackProcessor::midi_cc[128 *16]

MIDI CC control ports, 16 channels.

Definition at line 110 of file track_processor.h.

◆ midi_in

Port* TrackProcessor::midi_in

MIDI in Port.

This port is for receiving MIDI signals from an external MIDI source.

This is also where piano roll, midi in and midi manual press will be routed to and this will be the port used to pass midi to the plugins.

Definition at line 77 of file track_processor.h.

◆ midi_out

Port* TrackProcessor::midi_out

MIDI out port, if MIDI.

Definition at line 82 of file track_processor.h.

◆ monitor_audio

Port* TrackProcessor::monitor_audio

Whether to monitor the audio output.

This is only used on audio tracks. During recording, if on, the recorded audio will be passed to the output. If off, the recorded audio will not be passed to the output.

When not recording, this will only take effect when paused.

Definition at line 102 of file track_processor.h.

◆ mono

Port* TrackProcessor::mono

Mono toggle, if audio.

Definition at line 51 of file track_processor.h.

◆ output_gain

Port* TrackProcessor::output_gain

Output gain, if audio.

This is applied after regions are processed to TrackProcessor.streo_out.

Definition at line 62 of file track_processor.h.

◆ pending_midi_panic

bool TrackProcessor::pending_midi_panic

To be set to true when a panic (all notes off) message should be sent during processing.

Only applies to tracks that receive MIDI input.

Definition at line 153 of file track_processor.h.

◆ piano_roll

Port* TrackProcessor::piano_roll

MIDI input for receiving MIDI signals from the piano roll (i.e., MIDI notes inside regions) or other sources.

This will not be a separately exposed port during processing. It will be processed by the TrackProcessor internally.

Definition at line 91 of file track_processor.h.

◆ pitch_bend

Port* TrackProcessor::pitch_bend[16]

Pitch bend.

Definition at line 113 of file track_processor.h.

◆ poly_key_pressure

Port* TrackProcessor::poly_key_pressure[16]

Polyphonic key pressure (aftertouch).

This message is most often sent by pressing down on the key after it "bottoms out".

FIXME this is completely wrong. It's supposed to be per-key, so 128 x 16 ports.

Definition at line 124 of file track_processor.h.

◆ r_port_db

float TrackProcessor::r_port_db

Definition at line 142 of file track_processor.h.

◆ stereo_in

StereoPorts* TrackProcessor::stereo_in

L & R audio input ports, if audio.

Definition at line 48 of file track_processor.h.

◆ stereo_out

StereoPorts* TrackProcessor::stereo_out

L & R audio output ports, if audio.

Definition at line 67 of file track_processor.h.

◆ track

Track* TrackProcessor::track

Pointer to owner track, if any.

Definition at line 145 of file track_processor.h.

◆ updated_midi_automatable_ports

MPMCQueue* TrackProcessor::updated_midi_automatable_ports

A queue of MIDI CC ports whose values have been recently updated.

This is used during processing to avoid checking every single MIDI CC port for changes.

Definition at line 161 of file track_processor.h.
