The MKMidi Class

• MKMidi is a pseudo-MKPerformer in that it can't predict when the next MKNote will occur. However, it may be treated as any other MKPerformer.

• There may be two instances, one for each serial port. Thus, 32 MIDI channels are possible.

• MKMidi is a direct connection to the MIDI Device Driver. Similarly, MKOrchestra is a direct connection to the DSP. Both implement the following protocol:

  Table 3-6. Pseudo-MKPerformer Performance Protocol

  open	claims device
  run	starts device clock
  stop	stops device clock
  close	releases device after waiting
  abort	releases device without waiting

• To use MKMidi (or MKOrchestra), you must send run when you send startPerformance to the MKConductor. Example:

  [aMidi run]; [MKOrchestra run]; [MKConductor startPerformance];
