5 – The US-122 Control Panel
TASCAM US-122 — 19
Optimizing the USB
There is another option available which
allows you to disable the audio, and only
use the MIDI facilities of the US-122.
This is useful if you have a high volume
of MIDI data to be transmitted through
the interface and the timing is critical.
The Chromatic Tuner
Open the US-122’s control panel and
select the
Tuner tab.
In the
Input section, select the US-122
input channel that you want to tune (L or
R).
Play a note and adjust the level for that
input until the signal is strong, but not
clipping.
The
Level meter on the screen should dis-
play bright green segments without
lighting the top red segment.
If desired, you can change the
Tuning
Standard
in the Reference section. Nor-
mally, the
Tuning Standard is set to
440 Hz for a middle “A” note, but you
can use the up/down arrows to change it
to a number between 430 and 450 Hz.
As you play, the detected note will be
displayed below the
Tuning lights (A# or
E, for example). If the note is sharp, the
Sharp arrow and a Tuning light to the
right of
0 are bright red; if the note is
flat, the
Flat arrow and a Tuning light to
the left of
0 are bright red.
The numbers below the tuning lights
indicate how far out of tune the note is,
in cents (100 cents is one semitone).
When the note is in tune, the center ‘0’
light and both the
Flat and Sharp arrows
are bright green.
NOTE
The chromatic tuner consumes some CPU
bandwidth in your system. Therefore,
when you finish using the tuner, we recom-
mend that you either select another con-
trol panel tab or close the control panel.
