※ Open Sound Control

Compatible with iPad / iPhone / iPod touch
Requires iOS 4.0 or higher

FEATURES

The clean and simple interface provides an intuitive interaction with multi touch.
You can send coordinates for up to ten balls at one time. (for iPhone, iPod touch up to five)
Program has characteristic control from simulate of friction and bounce movement of the ball.
You can choose between two modes according to your needs.

A mode

B mode

The ball will appear on the coordinates that you have touched.
You can control the balls movements and the time until they disappear through settings of friction and duration. And you can also recieve the degree of transparency which as OSC value. This mode is for touch control.

You choose the number of balls, and control each balls coordinates.
The maximum number of balls is ten(for iPhone, iPod touch up to five). You can add or remove balls by using the "+/-" button. In this mode the balls don't disappear. It is for ranging or mixing control.

In each mode the balls speed can be controlled by setting friction.

Run this order to connect ALT OSC to MIDI Bridge.
Confirm the Port number is correct in OSC IN panel in the upper right corner of the window, and that the Active box is checked. When the controller of ALT OSC is operated, both of the lamps of OSC IN and the MIDI OUT panel light up.
Set the port of the MIDI OUT panel to "from MIDI Bridge 1" (Mac user)
Set the port of the receiving software to "from MIDI Bridge 1" too, and confirm MIDI is received.
Confirm receive of MIDI in receiving software with operating ALT OSC.
Using the Active box of the OSC IN panel (ON/OFF function of receiving OSC) and the ASSIGN button of each control panel (individual MIDI transmitting function) the parameter mapping is easy.
You can save the setting information to an external file if you wish to use it again later.
When you start of application, "default.json" is read in the same location as MIDI Bridge.

* For Windows user. In order to use "MIDI Bridge for FLICK PAD", you need to install "MIDI Yoke".

This sample shows how to control ALT OSC 3D model in detail.
In order to run this sample, you need "oscP5", the OSC library for Processing (developed by Andreas Schlegel).

PolyGranular

Polyphonic granular patch that is compatible with multi-touch devices that are designed for ALT OSC-FLICK PAD (Max5 or higher)
Used in A mode, X represents the position of playback time, and Y represents the grain size.
Also, by reading the information of the accelerometer and standing the iPhone/iPad vertically, the randomness parameter located on the play time will change.

You may read the audio file by clicking the replace button on the bottom of the screen or drag-and-drop to the center of the waveform display area.
Buttons 1-3 are used for the pitch change, you may also select octave-down, normal, or octave-up.

TIPS:
If you set the "Signal Vector Size" smaller on the Max DSP setting screen, the timing resolution will increase and reproduction quality will also increase when the grain size is small. (Default setting 64 is good for general use.)

*In the demo video, we play reverb over on the initial version.
*If you do not have Max, you need to install the Runtime. To download Runtime, click here.
