TASCAM MP-BT1 21
8 – Using the Tuner
The MP-BT1 has a built-in bass tuner and an oscillator
that can output any pitch between C4 and B6 To use the
tuner functions, press the MENU key to open the MENU
screen, and select and open the TUNER item.
MODE
Select from the following tuner modes.
BASS Bass tuning mode
AUTO Chromatic tuning mode
OSC. Oscillator mode
CALIB
You can adjust the frequency of A between 435 and 445
Hz. The value of this setting also appears at the bottom
right of the screen. This setting affects all tuner modes.
The following sections explain how to use each of the
three tuner modes.
Chromatic tuner mode (AUTO)
This is the default mode. In this mode, there is no need
to change settings as you tune each string.
1 With the bass connected to the BASS IN jack, play
the string that you want to tune. The note name
closest to the current string pitch appears.
2 Tune the string approximately until the note that
you want to tune to appears on the screen.
3 When the center of the meter lights, the string is
in tune.
A bar appears on the left side of the meter if the pitch is
too low, and on the right side if the pitch is too high. The
longer the bar is, the more out of tune the string is.
Bass tuner mode (BASS)
In this mode, you must manually set the note for each
string to be tuned.
1 Use the NOTE item to select the string that you want
to tune (1G, 2D, 3A, 4E, 5B).
2 When the center of the meter lights, the string is
in tune.
A bar appears on the left side of the meter if the pitch is
too low, and on the right side if the pitch is too high. The
longer the bar is, the more out of tune the string is.
Oscillator mode (OSC.)
Use the built-in oscillator to output a sine wave through
the /LINE OUT jack. You can set this wave to any note
in a 3-octave range between C2 and B4.
NOTE
Use this to set the pitch of the note to be output between
C2 and B4.
OUT
Use this to turn the oscillator output ON and OFF. When
ON, the onscreen tuning fork provides visual feedback.
LEVEL
Use this to set the output level (0–100) of the oscillator.
