A now-obsolete MIDI software package and interface standard developed, in the mid-1990s, by MOTU for tying sequencer software to MOTU’s line of MIDI interface hardware. Like OMS, the FreeMIDI system allows the user to build a description of what type of MIDI interface hardware is being used and which synths and other devices are using which channels. FreeMIDI then provides this information to the sequencer software, and the sequencer can address the MIDI devices without regard to what type of interface hardware is being used.
