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-Grid

The Sound-Grid, which looks like an actual harmonica hole arrangement, is a plane where touch makes a sound and its location determines its note. The numbers from 1 to 10 above each square corresponds to the harmonica hole number. The letters and numbers in each square represents the note assigned to there, and the notation can be selected from the note name, intervals from the root note, solfège notation, and so on; details are described in the "Settings" chapter of the User Guide.
Touching any square of the upper or lower side sounds the same note as blowing or drawing the same hole of an actual harmonica.
The dim zone between the adjacent squares is the Overlap, where a touch causes double-notes--both note of squares sound together.
You can change the width of the Overlap on the Utilities screen.
The Sound-Grid supports up to 2 independent touches for harmonica-like play such as octave playing and various splittings.
Touching two squares sandwiching one square sounds the notes of these three squares with the Smart Chord feature. For example, if you touch the “C” and “G” squares of upper side, a note of the "E" square will be also sounded.
You can set whether to use this feature on the Utilities screen.
In addition, shaking your touch finely to the left and right will cause vibrato in the sound; you can change the sensitivity of the vibrato on the Utilities screen.
The details of the function of the Sound-Grid are described in the "Utilities" chapter of the User Guide.

Sound Controller

The pitch and tone effect of the sound changes depending on the touch position of your finger placed on the Sound Controller. The dim area of the Sound Controller is the home area where the touch position does not significantly affect the sound.
The Sound Gauge is a gadget that allows you to check the position of the touch without being disturbed by your finger, and the dot inside it moves as a cursor that indicates the touch position.
The area surrounded by the two horizontal lines upper and lower of the gauge represents the range of the home area.
Moving the touch to the left from the home area also moves the cursor to the left, and makes bending (pitch down of the sound) accordingly.
The three vertical lines of the Sound Gauge are the bending scales, which indicate where the pitch is 1, 2, and 3 semitones down, respectively.
However, the maximum value that can actually be bent depends on each square of the Sound-Grid, just like a real harmonica; that value is shown by the count of dots at edge of the square (1 semitone per dot; half a semitone if there are no dots).
If it doesn't have to work like a real harmonica, every square can have 3 semitone bendable range by selecting the Free Bend feature on the Utilities screen.
Bending features are described in the "Utilities" chapter of the User Guide.
Moving the touch downward from the dotted line makes the sound muffled as if it's closed with your hand, and further moving below the home area makes it a bit weaker.
Conversely, moving the touch toward the ceiling causes a tremolo effect, and the tremolo cycle is faster as the touch is closer to the ceiling.
When you release the touch, the cursor will return to the middle of the home area;
Tip: You can express a manual tremolo with repeatedly tapping the bottom part of the controller.

Banner

Displays the current settings which are the pitch, key, tuning, sound, etc.
By touching the Banner and sliding the touch from left to right or right to left, you can select the preset settings in order or reverse order.
The details are described in the "Settings" chapter of the User Guide.

Wanna get started right away? But wait a moment

By making good use of them, you can handle this instrument as if you were playing a harmonica; immediately after launching this app, the instrument key is "C" and the tuning is "Major".
You can enjoy playing as it is, but understanding many of the features of this app that you can access from the menu will allow you to take advantage of this instrument in more ways.

Menu

Tapping the Menu button at the top right brings down a row of menu icons, which will disappear by touching anywhere on the screen.

The tab-bar screen or the User Guide relating to the icon will appear by tapping one of these icons.
Note: Be sure to release all touches from the screen when tapping the menu to prevent unexpected operation.

Icon	Screen	What you can do

Each tab of the tab-bar has the same icon as the menu.
Tip: The selected tab also serves as a shortcut to the User Guide page for the shown screen; further tapping the selected tab will invoke that page.
To return to the Main screen, tap the "Done" tab at the left end of the tab-bar.

User Guide

The User Guide explains all of the features of this application that organized by relevant tab-bar screen.
Tapping the icon in the Menu will invoke the first page of the User Guide: "Quick Start"--this page.
You can navigate through the User Guide by the navigation bar at the bottom.
Tip: Swipe gesture on the page from the left (right) edge to the right (left) turns the page backward (forward).
To return to the original screen, tap the "Done" at the left end of the navigation bar.
Tip: For your convenience, a quick how-to is in the first section of the appendix.
