Main Screen

The Main screen is the screen for performing music, and configured as follows.

How to Hold

Place the device horizontally in your left palm.
Put your left thumb on the center of the home area in the Sound Controller. It's also a good idea to place your right thumb or left little finger at the bottom of the device to support it.
Note: Mind the direction of the device so that your palm does not cover the device sound output.

Sound-Buttons

The Sound-Buttons is an area where multiple buttons that make a sound when touched are arranged. Each button is laid out along a certain scale in a zigzag pattern from left to right in order from the lowest note. The layout is usually according to the major scale, but you can also choose from several layouts along the minor, blues scale, and so on.
The buttons assigned to the root of the scale are rounded rectangles. The letters and numbers in each button indicate the note assigned to that button, and its notation can be selected from note names, intervals, solfege notation (doremi), and so on. In addition, the Sound-Buttons can be shifted in 3 steps, high and low, to match the actual playing range.
You can make these settings and changes on the Settings screen.
Details are described in the "Settings" chapter of the User Guide.
The Sound-Buttons supports touches up to two fingers and always prioritizes later touches (if the later touch is released before the previous touch, it reverts to the previous touch). This allows for smooth legato even when playing jumping between distant buttons.
The two gradient dim areas are the upper and lower touch plates that act as semitone keys. By touching it, you can raise or lower the pitch by 1 semitone, and at the same time, "#" or "♭" will be displayed on the right side of the Sound-Gauge.
You can apply tremolo (volume vibrato) by shaking finely your finger while touching the sound button.
You can change the tremolo direction and sensitivity on the utilities screen.
See the Utilities chapter in the User Guide for more details including other features.

Sound Controller

The attack and pitch of the sound changes depending on the touch position of your finger placed on the Sound Controller. The dimly colored square area in the controller is the home area, where the pitch does not change with the touch position.
The Sound-Gauge is a gadget for checking the position of the touch without being disturbed by your finger. The three lines of the gauge represent the center and the upper and lower edges of the home area, and the dots move as cursors indicating the touch position.
Moving the touch to the top will increase the attack of the sound as if you were playing with "tonguing". Conversely, moving to the bottom will soften the attack and further down from the bottom line will weaken the sound.
Moving the touch to the left from the home area causes pitch bending, dropping up to 2 semitones (200 cents) as touch moves away from the home area.
When you release the touch, the Sound-Gauge cursor will return to its original position.

Banner

Displays the settings currently being applied: pitch, key, tuning, sound, etc.
The details are described in the "Settings" chapter of the User Guide.
