Calibrating The Tuner; Tuning Your Instrument - Roland VG-99 Workshop Manual

A divided pickup is required for the VG-99's tuner to simultaneously
respond to the separate pitches of the guitar's six strings. If you're
using just your guitar's regular pickups with the VG-99, the tuner can
only respond to one string at a time, and playing more than one pitch
will confuse the tuner. Additionally, in the Multi mode display, the
pitch of any string played is shown only on the top line.
Single Mode
On Page 2, the tuner display is in Single mode. In this mode, the tuner can
respond to only one pitch at a time, which is shown in the center of the
display. When you're using a divided pickup, the number of the currently
played string is highlighted in the upper left-hand corner of the display.
String number Pitch
If you're using just your guitar's regular pickups with the VG-99, the
STRING display in the upper left-hand corner is not shown.

Tuning Your Instrument

In either tuner mode, when you play a string, its current pitch is displayed.
Tune the string so that the desired pitch is shown.
When the desired pitch is displayed, fine tune the string until it's in tune. The
arrows on either side of the displayed pitch show if the pitch is sharp or flat
(if the right arrows light, the pitch is sharp; if the left arrows light, the pitch
is flat.) The string is in tune when both large arrows light steadily and the
pitch is highlighted.
Even when using a divided pickup in Multi mode, you'll usually achieve
the best results by playing and tuning one string at a time. Play the
desired string in open position or at its 12th-fret harmonic.

Calibrating the Tuner

As shipped from the factory, the VG-99's tuner is
calibrated to the standard 440 Hz reference. Most of
the time, you'll want to keep it there. However, there
may be occasions when you need to calibrate the
tuner to a slightly different pitch.
From either TUNER screen, you can calibrate the tuner by using
the F5 button or knob to set the reference pitch anywhere
from 435-445 Hz. The current reference is shown under PITCH
on the right-hand side of the tuner display.
440 Hz—or "A-440"—is the tone that serves as the international
standard reference pitch for tuning musical instruments. This pitch is
the musical note "A" in the fourth octave on the standard piano. On
the piano keyboard, it's the A note above middle C. Most tuning forks
produce the 440 Hz reference pitch.
Muting the VG-99's Output While Tuning
It's handy to mute the sound while tuning, so that your audience is spared
from hearing this necessary but utilitarian chore.
From either TUNER screen, use the F6 knob or button to toggle
the tuner's mute function on and off. The current setting
is shown under MUTE on the right-hand side of the tuner
display.
•
When MUTE is ON— the VG-99's outputs are silenced when the tuner is
on.
•
When MUTE is OFF— the sound is output as normal when the tuner is
on.
Muting the VG-99's output by turning on the tuner is useful for other
things besides tuning, such as silencing your rig when you're on a
set break at a gig, or avoiding a "pop" when switching a cable to a
different guitar.
