Quick Start

CC Harp consists of Main screen and several sub-screens: Settings, Utilities, PlayAlong, and Synthesizer, and a User Guide (this document).
Details of each sub-screen are described on the explanation page for each screen.
Note: Explanations related to sub-screens is applied if you have purchased Extra Features, Extra Features Trial or paid version.

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.

The Main screen layout can be flipped for left-handed users with the "Left-Handed" switch in the "CC Harp" section of the device settings app.
Settings > CC Harp > Left-Handed


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.
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. 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.

Size, Position and Direction of the Sound Controller
You can adjust the size, position and direction of the sound controller in the utilities screen, accessed from the menu.
for more information, see the "Utilities" chapter of the user guide.


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.

Enjoy the Performance
