Rosco
DOWNLOAD version 2.0
Rosco is a Mac OS X application that creates OSC messages from a set of sliders and checkboxes. It also takes serial data from an arduino (or anything else that can implement the pseudo protocol I’ve created for this project) and translates the values into OSC data.
Features:
6 sliders and 12 checkboxes that will transmit OSC data. The project includes Arduino code and a Quartz Composer file that you can use to rebroadcast the OSC messages out to your network. You can use the OSC messages from Rosco with PD, Processing, Max/MSP, Osculator, or anything else that can utilize OSC messages without using the arduino or quartz composer file.

Instructions:
Launch Rosco. Set the horizontal sliders to somewhere in the middle so you can get a feel for what they do. Now you can adjust the vertical sliders and see what the interpolation duration does. As the vertical sliders are translating from one position to the another, the values are broadcasting through OSC to port 127.0.0.1 on port 60000.
* Arduino usage is not required. But it’s fun, so load up the .PDE that I’ve included onto your arduino.
* Launch quartz composer with the included .qtz file. This will receive the incoming OSC messages and give you an easy way to use the values or rebroadcast them to another IP address and/or port.
* have fun? Send bug reports to steve@sc-fa.com or do me a favor and report it here.
Version History:
Version 2.0 – 2009-04-16
DOWNLOAD
* arduino digital pins 2 through 13 are now supported! Pins 0 and 1 are the TX/RX pins, which is what the arduino thinks it’s using to talk to the computer… Oh well. I can’t see how to get around this for now. Maybe I can re-acquire one of those pins? Not sure.
* application icon created and buncha other app dev stuff “fixed” so Rosco acts like the real app it is.
* the optional starter external quartz composer file has been updated to accept data from the 12 digital pins as boolean values.
* the arduino code has the ability to invert the analog values. Look towards the top for the “invert” “notinverted” stuff and edit as you need to, and upload to your arduino. The feedback I got on my hardware was that the potentiometers felt backwards, so I am not inverting the values so that they “feel” right.
Version 1 – 2009-01-20 initial release
* Receiving serial data from the analog pins is working. interpolation curve duration and style selector is working.
* .pde, cocoa app, and external .qtz file all functional to send serial data from an arduino board on the 6 analog pins to the AMSerialPort library, unmunged and sent to an internal QC composition that handles smoothing and broadcasting of the values to port 127.0.0.1 on port 60000.
