/*
A quick ChucK script to accept accelerometer coordinates from the iOS app TouchOSC and use those coordinates to control a sound.
TouchOSC needs to be set up properly, in its preferences (from any layout, those can be accessed through a button at the top-right corner).

The app needs to be running on the same (WiFi) network as this ChucK script and it needs to be associated with the right host: "OSC" is enabled, "Host" is the IP address or network name of the device where this script is running, the "Port (outgoing)" is set to the proper port.

In the case of a RaspberryPi running an unmodified version of Raspbian, the Host would be "raspberrypi.local". The port used in this script is 6449, an arbitrary number used in the ChucK-based book "Programming for Musicians and Digital Artists" (PMDA) which served as the basis for this script.

TouchOSC needs to be sending accelerometer values, which is in the "OSC" section of "Options": "Accelerometer (/xyz)" should be on (green).

/*
A quick ChucK script to accept accelerometer coordinates from the iOS app TouchOSC and use those coordinates to control a sound.
Originally setup the z coordinate to control a filter, before noticing that most ChucK oscillators accept “width” as a parameter. Sending the z coordinate to this parameter instead, simplifying the code from the previous version.

TouchOSC needs to be set up properly, in its preferences (from any layout, those can be accessed through a button at the top-right corner).
The app needs to be running on the same (WiFi) network as this ChucK script and it needs to be associated with the right host: 
* "OSC" is enabled
* "Host" is the IP address or hostname of the device where this script is running
* The "Port (outgoing)" is set to the proper port.
