The MKNote Class

• A MKNote consists of:

  • a noteType and a noteTag

  • a set of parameters

  • an optional timeTag and duration

• There are 5 types of MKNotes, represented by the noteType:

  • noteOn - start of a musical phrase or rearticulation

  • noteOff - end of a musical phrase

  • noteDur - a noteOn with a duration

  • noteUpdate - update to a running musical phrase(s)

  • mute - none of the above

  (in an MusicKit program, a prefix is required, as in MK_noteOn)

• The noteTag groups a series of noteOns and noteUpdates with a single noteOff. This is called a phrase.

  noteTag is essential for noteOn and noteOff

  noteTag is optional for noteDur and noteUpdate

  noteTag is not used for mute

• A noteUpdate without a noteTag applies to all running patches and is “sticky”.

• A noteDur represents a noteOn/noteOff pair. If another noteOn with the same noteTag appears before the duration is expended, the implied noteOff is canceled.

• The timeTag refers to the location of the MKNote in a MKPart and is only used in that context. Its value is in beats.
