ICST MultiEncoder and iOS GyrOSC.app

GyrOSC is a lightweight utility that sends motion sensor data (from your iPhone, iPod Touch, or iPad) over a local wireless network to any OSC-compatible host application. It allows you to control live audio or video applications using your device’s built-in gyroscope, accelerometer, compass, and altimeter.

How it works:

This tutorial is a short step-by-step guide on how to use the iOS app ‘GyrOSC’ with the ICST Ambisonics Encoder.

How It Works:

This tutorial provides a step-by-step guide on using the iOS app GyrOSC with the ICST Ambisonics Encoder.

Setting Up the GyrOSC App:

  1. Download the GyrOSC app.
  2. Configure the app as follows:
    • Enable Gravity (disable all other sensors).

OSC Configuration in GyrOSC App:

  1. Enter the IP address of your machine in field (1).
  2. The default port number for the ICST Ambisonics Encoder is 50001 (field 2).
  3. Choose the index (source-number) for the plugin in field (3).
  4. Field (4) shows the OSC message sent by GyrOSC.

GyrOSC_Config

The GyrOSC app will send the ‘Gravity’ data via OSC (port 50001) to the ICST MultiEncoder.

Setting Up the ICST Ambisonics Encoder Plugin:

Reaper_GyrOSC

  1. Open the ICST AmbiEncoder_64 plugin.

  2. Access the Encoder Settings.

  3. Open the OSC IN section and enable OSC-IN (port: 50001).

  4. Double-click in the OSC-Message field and enter:

    /gyrosc/{i}/grav {x} {y} {z}

  5. Enable the plugin by selecting en.

  6. Move your iPhone to generate motion data.

OSC-Message:

/gyrosc/1/grav

JS-Code:

s.setXYZ(1, s.arg(2), -s.arg(1), 0); for(i = 2; i <= 8; i++) s.setXYZ(i, s.arg(2)+Math.random()*0.2, -s.arg(1) + Math.random()* 0.2, 0)
