If you are using an application that has MIDI output only (not OSC), you can make good use of one of the following applications for sending MIDI over OSC to Kyma (removing the need for a MIDI interface on your computer):
Andy Capon's OSCKymaMIDI (for Max and Max for Live)
If you are writing your own software to send MIDI events over OSC or would like to develop your own MIDI over OSC application (or translator), please see the section: For software developers
