Useful Functions
The MICRO CUBE RX is equipped with a tuner function. In addition
to manual tuning, you can also use it as a chromatic tuner.
* Use manual tuning when the strings are substantially out of tune
(such as after changing strings).
Manual Tuning
1. Press the TUNER button.
The unit enters Tuner mode, and the TUNER button lights. When the
unit is in Tuner mode, no sound is played through the speakers
or the REC OUT/PHONES jack.
2. Use the AMP TYPE
knob to select the
string that you
want to tune.
3. Play a single note on the open string that you want to tune.
Tune the string until the green indicator lights.
* The red indicator flashes if the pitch is substantially out of tune.
4. When you have finished tuning, press the TUNER button once
again.
* The reference pitch is A=440 Hz. This cannot be changed.
Chromatic Tuning
If you press the TUNER button for one second or more, you can also use
the unit as a "chromatic tuner", which automatically determines the closest
note name to the one played.
As with manual tuning, chromatic tuning allows you to play a single note on
the string that you want to tune. Tune the string until the green indicator lights.
The MICRO CUBE RX is equipped with drum/percussion-based rhythm
patterns that are useful for solo practicing. In addition to practicing with
your desired beat, you can also use it as a metronome.
1. Select the rhythm genre using the PATTERN knob.
METRONOME
ROCK1 ROCK2 BLUES
COUNTRY R&B BALLAD JAZZ
FUNK LATIN DANCE
2. Press the START/STOP button to start the RHYTHM GUIDE.
When the RHYTHM GUIDE is started, the RHYTHM GUIDE indicator
lights.
3. Adjust the RHYTHM GUIDE volume using the RHYTHM GUIDE
VOLUME knob.
4. Select a rhythm variation by pressing the VARIATION button.
Each genre contains three types of rhythm variations. Pressing
the VARIATION button cycles you through the available variations;
the VARIATION indicator will be unlit, will light green, or will light
red to indicate the change in variation.
5. Adjust the variation to the tempo that you want to play to.
Press the TAP TEMPO button two or more times at the desired tempo
to get the RHYTHM GUIDE to play at that tempo.
