Inter-Application MIDI

Many modern MIDI based software applications have the ability to communicate MIDI data with each other inside the computer. Generally this takes the form of some type of synchronization information such as MIDI clock, MTC, or actual MIDI performance data. The idea is to allow two programs that may or may not be independent applications to directly communicate necessary MIDI data with each other without having to route that data out of the computer’s MIDI interface and then right back in on another port. Inter-Application MIDI has sort of taken over where the IAC left off a few years ago, but it is essentially the same technology.
