MidiMessage class public functions

---

Data access

unsigned long time;

Storage space for a timestamp assiciated with the MIDI message.



unsigned long date;

Storage space for one MIDI command message with up to 3 parameter bytes which are accessed through functions p0 through p3.



uchar& p0(void);

The MIDI command byte for the MIDI message.



uchar& p1(void);

The first parameter byte for the command byte in p0. Validity of parameter depends on MIDI command.



uchar& p2(void);

The second parameter byte for the command byte in p0. Validity of parameter depends on MIDI command.



uchar& p3(void);

The third parameter byte for the command byte in p0. Validity of parameter depends on MIDI command.

Other functions

MidiMessage(void);

Does nothing. Initial contents are undefined.

MidiMessage(int aCommand, int aP1, int aP2, int aTime = 0);

Sets the MIDI data and timestamp fields of object.

MidiMessage(const MidiMessage& aMessage);

Copies the data and timestamp of the given input message.



~MidiMessage();

Does nothing.



uchar& command(void);

Accesses the MIDI message command byte. Same behavior as p0 function.



uchar getCommand(void) const;

Accesses the MIDI message command byte. Similar behavior as the command function.



int getParameterCount(void) const;

Returns the number of valid parameters for the assiciated MIDI command stored in p0. Returns -1 if MIDI command is invalid, or the number of valid parameters is unknown



uchar getP0(void) const;

Accesses the MIDI message command byte. Similar behavior as the p0 function.



uchar getP1(void) const;

Returns the first message parameter following the command byte in the MIDI message. Similar behavior to p1.



uchar getP2(void) const;

Returns the second message parameter following the command byte in the MIDI message. Similar behavior to p2.



uchar getP3(void) const;

Returns the third message parameter following the command byte in the MIDI message. Similar behavior to p3.



MidiMessage& operator=(const MidiMessage& aMessage);

Copies information between MidiMessages.



void setCommand(unsigned char aCommand);

Sets the command byte of the MIDI message. Similar in behavior to the command function.



void setData(unsigned char aCommand, unsigned char aP1 = 0, unsigned char aP2 = 0, unsigned char aP3 = 0);

Sets the message bytes of the MIDI message.



void setP0(unsigned char aP0);

Sets the command byte of the MIDI message. Similar in behavior to the p0 function.



void setP1(unsigned char aP1);

Sets the first parameter byte of the Midi message following the command byte. Similar in behavior to the p1 function.



void setP2(unsigned char aP2);

Sets the second parameter byte of the Midi message following the command byte. Similar in behavior to the p2 function.



void setP3(unsigned char aP3);

Sets the third parameter byte of the Midi message following the command byte. Similar in behavior to the p3 function.
