System information
MIDI Clock
A MIDI device specific timing reference. It is not absolute  time like MTC, instead it is a tempo dependent 
number of "ticks"  per quarter note. MIDI Clock is convenient for synching devices that need  to do tempo 
changes mid-song. Vegas Pro supports MIDI Clock out,  but does not support MIDI Clock in.
MIDI Port
A MIDI Port is the physical MIDI connection on a piece of  MIDI gear. This port can be a MIDI in, out or 
through. Your computer must  have a MIDI to output MIDI Time Code to an external device or to receive  
MIDI Time code from an external device.
MIDI Time Code (MTC)
MTC is an addendum to the MIDI 1.0 Specification and provides  a way to specify absolute time for 
synchronizing MIDI capable applications.  Basically, it is a MIDI representation of SMPTE timecode.
Mix
A function Vegas Pro performs inherently by adding  events to multiple audio tracks.
Multiple Stereo
A mixer configuration that allows you to assign individual  tracks to any number of stereo output busses. In 
single stereo mode, all  tracks go out the same stereo bus. Multiple stereo configuration allows  you to keep 
your signals from the tracks discrete if you want them to  be.
Musical  Instrument Device Interface (MIDI)
A standard language of control messages that provides for  communication between any MIDI compliant 
devices. Anything from synthesizers  to lights to factory equipment can be controlled via MIDI. Vegas Pro  
utilizes MIDI for synchronization purposes.
N
Noise-shaping
Noise-shaping is a technique that can minimize the audibility  of quantization noise by shifting its frequency 
spectrum. For example,  in 44,100 Hz audio quantization noise is shifted towards the Nyquist Frequency  of 
22,050 Hz.
Nondestructive Editing
This type of editing involves a pointer-based system of  keeping track of edits. When you delete a section of 
audio in a nondestructive  system, the audio on disk is not actually deleted. Instead, a set of pointers  is 
established to tell the program to skip the deleted section during  playback.
