The MKUnitGenerator Class

• You can allocate a MKUnitGenerator from an open MKOrchestra.

  [orch allocUnitGenerator: [Out2sumUGx class]];

• An allocated MKUnitGenerator is, by definition, running on the DSP. You can deallocate a MKUnitGenerator by sending:

  [aUnitGenerator release];

• MKUnitGenerators are in one of three possible states:

  Table 4-2. MKUnitGenerator States

  MK_idle	Disconnected, not usable.
  MK_running	Running
  MK_finishing	Envelope release

• To set these states you send the following standard messages:

  idle, run, finish

• These invoke the following methods, which you may implement if you make your own MKUnitGenerator class:

  idleSelf, runSelf, finishSelf

• The return value of finish (and finishSelf) is a double that indicates the time until the MKUnitGenerator will be finished.

• In addition to these standard methods, individual MKUnitGenerator classes implement methods particular to their operation. Common methods include setInput: and setOutput:. E.g. oscillators implement setFreq:.
