Detailed Description

This MIDIProcessor subclass implements a matrix which keeps track of notes on and hold pedal for every channel.

Every time you call Process() giving it a MIDITimedMessage it updates the count of notes on and pedal (it does nothing if the message is not a note or pedal message). It is used by MIDIDriver and MIDISequencerTrackState.

Constructor & Destructor Documentation

MIDIMatrix()

MIDIMatrix::MIDIMatrix

(

)

The constructor creates an empty matrix.

~MIDIMatrix()

virtual MIDIMatrix::~MIDIMatrix ( )

inlinevirtual

The destructor.

Member Function Documentation

Reset()

virtual void MIDIMatrix::Reset ( )

virtual

Resets the matrix (no notes on, no pedal hold)

Implements MIDIProcessor.

Process()

virtual bool MIDIMatrix::Process ( MIDITimedMessage *  msg )

virtual

Processes the given MIDI message updating the matrix.

Returns true if the message has changed some matrix parameter, false otherwise

Implements MIDIProcessor.

GetTotalCount()

int MIDIMatrix::GetTotalCount ( ) const

inline

Returns the total number of notes on.

GetChannelCount()

int MIDIMatrix::GetChannelCount ( int  chan ) const

inline

Returns the number of notes on for given channel.

See Numbering conventions.

GetNoteCount()

int MIDIMatrix::GetNoteCount ( int  chan, int  note  ) const

inline

Returns the number of sounding notes given the channel and the note MIDI value.

See Numbering conventions.

GetHoldPedal()

bool MIDIMatrix::GetHoldPedal ( int  chan ) const

inline

Returns true if pedal is holding on given channel.

See Numbering conventions.

GetMinNoteOn()

int MIDIMatrix::GetMinNoteOn ( int  chan ) const

inline

Returns the minimum note on MIDI value sounding for the given channel (-1 if no note on).

See Numbering conventions.

GetMaxNoteOn()

int MIDIMatrix::GetMaxNoteOn ( int  chan ) const

inline

Returns the maximum note on MIDI value sounding for the given channel (-1 if no note on).

See Numbering conventions.

DecNoteCount()

virtual void MIDIMatrix::DecNoteCount ( unsigned char  chan, unsigned char  note  )

protectedvirtual

Decrements the note count for the given channel and note.

See Numbering conventions.

IncNoteCount()

virtual void MIDIMatrix::IncNoteCount ( unsigned char  chan, unsigned char  note  )

protectedvirtual

Increments the note count for the given channel and note.

See Numbering conventions.

ClearChannel()

virtual void MIDIMatrix::ClearChannel ( unsigned char  chan )

protectedvirtual

Clear the note count and the pedal on the given channel.

See Numbering conventions.

OtherMessage()

virtual void MIDIMatrix::OtherMessage ( const MIDIMessage *  msg )

inlineprotectedvirtual

Called by Process() for non note and non pedal messages.

You can redefine it if you want your own processing (currently does nothing)

SetNoteCount()

void MIDIMatrix::SetNoteCount ( unsigned char  chan, unsigned char  note, unsigned char  val  )

inlineprotected

Sets the note count.

See Numbering conventions.

SetChannelCount()

void MIDIMatrix::SetChannelCount ( unsigned char  chan, int  val  )

inlineprotected

Sets the channel note count.

See Numbering conventions.
