Guitar (Hi-Z); Ntsc Format - Roland VS-2480 Supplementary Manual

Formants
A formant is an important element which determine the
character of a vocal sound. It is a fixed overtone whose
location is determined by the size of the vocal chords.
Conventional pitch shifters modify the pitch in a way that
changes even the location of the formants (which by nature
do not change). For example when a conventional pitch
shifter raises the pitch, a "duck voice" is produced as if the
vocal chords had shrunk, and when the pitch is lowered a
"giant voice" is produced as if the vocal chords had
expanded.
The Voice Transformer modifies the basic pitch and the
formant separately, allowing a variety of voice characters to
be created.
Frame
Similar to the individual frames in a roll of movie film, the
numerous still pictures that are displayed in rapid succession
to create a moving video image are also known as "frames."
About thirty of these frames are shown each second. When
hard disk recorders, sequencers, and other such equipment
are synchronized with video, it is generally assumed that
there should be one frame every 1/30th of a second.

GUITAR (Hi-Z)

A high-impedance input jack for directly connecting electric
guitars.
GPI
GPI stands for General Purpose Interface. This is a control
jack provided on professional and consumer video devices
such as video editors and title superimpoters. By connecting
this control jack to the foot switch jack of the VS-2480/
2480CD and setting the Foot Switch Assign to "GPI," the
connected device will be able to playback/stop the VS-2480/
2480CD.
IDE
IDE stands for Integrated Device and Electronics. This is
the standard data transmission method used by the hard disk
drives of recent personal computers. The HDP88 series hard
disk drives (sold separately) that can be installed in the
VS-2480/2480CD are IDE compatible.
Limiter
An effect that works similarly to a compressor. When the
input signal rises beyond a specified level (threshold), a
limiter instantly lowers the gain to limit the output level. The
degree of compression is specified by the Ratio. In general,
ratios of 1:10 or less are referred to as compression, in
distinction to limiting.
MMC
MMC is an acronym for MIDI Machine Control. This is rule
that defines how MIDI system exclusive message can be used
to control multiple recording devices from a single device.
The VS-2480/2480CD supports MMC. In addition to song
playback, stop and fast-forward, you can also select the
tracks for recording, etc.
MTC
MTC stands for MIDI Time Code. This is a group of
messages which are transmitted and received between MIDI
devices to synchronize their operation. Unlike MIDI Clock
messages, MTC specifies an absolute time. Like SMPTE time
code, MTC also supports a variety of frame rates. If you wish
to use MTC to synchronize the operation of two devices, both
devices must be set to the same frame rate.

NTSC Format

Color television format used in Japan, the United States, and
other countries. Tapes recorded in the NTSC format cannot
be played back on video decks utilizing the SECAM/PAL
formats.
Oscillator
A device that generates an alternating signal. On this system,
the term refers to the internal oscillator used to sound a
reference tone for measurement by the spectrum analyzer. It
is able to produce a 20 Hz–20 kHz sine wave, pink noise and
white noise.
