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.
First connect your MIDI interface to your computer. A USB cable is normally used for this. Then connect each MIDI instrument to your MIDI interface. TIP!! Remember the IN on your interface goes to the OUT on your instrument and the OUT on your interface goes to the IN on your instrument. Once you've got it, go back and double check it. This is the most common mistake when setting up a MIDI studio.
