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.
An audio interface is a device which connects your various audio equipment to your computer (microphones, guitars, studio monitor speakers, etc). They can provide phantom power to amplify your microphones, hook up any MIDI device youâve got, and use an XLR port for a microphone. Audio interfaces convert the analog information into digital signals for your computer to recognize and lay down into your songs.
