Abstract: This metric is the ratio of the maintenance personnel who are actively doing the maintenance work (direct) to the maintenance personnel supporting the maintenance work (indirect). Direct personnel include those workers in the maintenance department that repair, maintain, modify or calibrate equipment.
MIDI (Musical Instrument Digital Interface) is a protocol designed for recording and playing back music on digital synthesizers that is supported by many makes of personal computer sound cards. Originally intended to control one keyboard from another, it was quickly adopted for the personal computer.
Introduction to Sequencers. In the world of MIDI, a sequencer is any hardware or software device that can precisely play or record a sequence of time-stamped MIDI messages. Similarly, in the Java Sound API, the Sequencer abstract interface defines the properties of an object that can play and record sequences of MidiEvent objects.
