Members

beat

Beat count (within a measure) at which this note occurs.

durRange

Range to randomize duration.

flags

Should be set to DMUS_NOTEF_NOTEON. See Remarks.

grid

Grid offset from a beat at which this note occurs.

measure

Measure in which this note occurs.

midiValue

MIDI note value, converted from musicValue.

mtDuration

Duration of the note.

musicValue

Description of the note. In most play modes, this is a packed array of four-bit values, as follows:

Octave, in the range from –2 through 14. The note is transposed up or down by the octave times 12.

Chord position, in the range from 0 through 15, though it should never be above 3. The first position in the chord is 0.

Scale position, in the range from 0 through 15. Typically, it is from 0 through 2, but it is possible to have a one-note chord and have everything above the chord be interpreted as a scale position.

Accidental, in the range from –8 through 7, but typically in the range from –2 through 2. This represents an offset that takes the note out of the scale.

In the fixed play modes, the music value is a MIDI note value in the range from 0 through 127.

offset

Offset from a grid at which this note occurs, in music time.

playModeFlags

Play mode determining how the music value is related to the chord and subchord. For a list of values, see CONST_DMUS_PLAYMODE_FLAGS.

subChordLevel

Subchord level that the note uses.

timeRange

Range by which to randomize time.

velocity

Note velocity.

velRange

Range by which to randomize velocity.

Remarks

Applications sending note messages must provide values only in the flags, midiValue, mtDuration, and velocity members. The other members are of interest only to tools, which are not supported in DirectX for Visual Basic.

Normally, the application sets flags to DMUS_NOTEF_NOTEON. The application is not responsible for sending note-off messages. When the DirectMusic output tool receives a DMUS_NOTE_PMSG and sees that DMUS_NOTEF_NOTEON is set, it clears the flag, adds mtDuration to the time stamp, and requeues the message so that the note is turned off at the appropriate time.

It is possible, however, for the application to stop a note prematurely by sending the same note on the same channel with flags set to 0.
