Below is an example of using PureData to convert OSCemote messages into a MIDI messages for use in any MIDI compatible software.

Simple PureData Example

• First download and open this simple PureData file
• Now launch OSCemote on your iPhone or iPod Touch.
• Open your computer's network settings control panel to find your WiFi IP address (usually something like 10.0.1.2 or 192.168.0.2)
• Go to the Settings tab in OSCemote and enter the IP address of your computer.
• Make sure the port number in OSCemote and PureData's "dumpOSC" object match (usually 3333).
• Also make sure your computer's firewall will allow UDP traffic on the port you are using.
• Now switch to the buttons, sliders or multi-touch view in OSCemote and press something.
• You should see the values from the button, slider or touch appear in the PureData window.

OSC to MIDI Bridge

• First download and open this fancy PureData file
• Now follow the same steps as the simple example above.
• You should now see PureData responding to OSCemote.
• If you have an external MIDI device plugged in to your machine it will now receive MIDI notes.
