MKNote Parameters

• Parameters consist of an integer identifier and a value.

  Table 2-1. Examples of MKNote Parameters

  Examples:	identifier	value
  	MK_freq	440
  	MK_amp	0.4
  	MK_waveform	“SA”

• The MusicKit defines a number of parameters. These begin with the “MK_” prefix. In addition, you can define your own with [MKNote parTagForName: @"myParameter"]

• Parameter values may be one of the following types:

  • int

  • double

  • NSString

  • MKEnvelope

  • MKWaveTable

  • any object (e.g. a param's value could be a MKScore)

• The object that realizes the MKNote determines how to interpret the parameters. Any parameters it doesn't care about are ignored. This makes reorchestration easy.

• The MKNote class does automatic type conversion where possible. Thus, the consumer of a MKNote parameter need not concern himself with how the parameter was set.
