SequencerM1

Implements a MIDI v1.0 sequencer.

Since MIDI v2.0 isn't widespread (and seems like I even have to implement my own format) and v1.0 is widespread and still capable enough (even if getting the most out of it needs some klunkiness), I'm creating an internal sequencer for this format too. By using multiple tracks, it's able to interface with multiple modules.

Constructors

this this(AudioModule[] modules, uint[] routing, ubyte[] routGrp): Undocumented in source.

Members

Enums

Status enum Status: Undocumented in source.

Functions

enableLoop bool enableLoop(bool val): Enables looping (marked with LOOPBEGIN and LOOPEND), then repeates the MIDI data between these points until either looping gets disabled, or the sequencer gets shut down.
lapseTime void lapseTime(Duration amount): Makes the sequencer to go forward by the given amount of time, and emits MIDI commands to the associated modules if the time have reached that point.
openMIDI void openMIDI(MIDI src): Loads a MIDI file into the sequencer, and initializes some basic data.
pause void pause(): Pauses the sequencer. Note: Won't pause states of associated modules.
reset void reset(): Resets the sequencer.
setTimeDiv void setTimeDiv(uint usecPerQNote, size_t track): Sets the time division for the given track
start void start(): Starts the sequencer.
stop void stop(): Stops the sequencer.
ticsToDuration Duration ticsToDuration(int tics, size_t track): Converts MIDI tics to Duration.

Variables

lp_positionTime Duration[] lp_positionTime;: Save states for looping.
lp_trackState ubyte[] lp_trackState;: Undocumented in source.
lp_usecPerTic uint[] lp_usecPerTic;: Undocumented in source.
modules AudioModule[] modules;: Module list.
positionBlock size_t[] positionBlock;: Current event position for all individual tracks.
positionTime Duration[] positionTime;: Current time position for all individual tracks.
routGrp ubyte[] routGrp;: Group routing for each module.
routing uint[] routing;: Routings for multi-track MIDI files.
src MIDI src;: Source file deconstructed.
status uint status;: Stores status flags, see enum Status
trackState ubyte[] trackState;: States of the tracks. Bit 0 : End of track marker has reached.
usecPerTic uint[] usecPerTic;: Precalculated microseconds per tic (per track) for less complexity.
