Open Sound Control (OSC)

• Open-ended, dynamic, URL-style symbolic naming scheme
• Transport independent
• Numeric and symbolic arguments to messages
• Pattern-matching language to specify multiple recipients of a single message
• High resolution time tags
• "Bundles" of messages whose affect must occur simultaneously
• Query system to dynamically determine the capabilities of an OSC server and get documentation
• "/oscillator/4/frequency 440.0" represented by 32-byte message:

   2f (/)  6f (o)  73 (s)  63 (c)
   69 (i)  6c (l)  6c (l)  61 (a)
   74 (t)  6f (o)  72 (r)  2f (/)
   34 (4)  2f (/)  66 (f)  72 (r)
   65 (e)  71 (q)  75 (u)  65 (e)
   6e (n)  63 (c)  79 (y)  0 ()
   2c (,)  66 (f)  0 ()    0 ()
   43 (C)  dc (Ü)  0 ()    0 ()

• Biggest problem: no standardization of OSC address patterns, interconnectivity of devices
• More OSC information
