Link to MIDI = Ableton Link to MIDI Clock Sync.

Link to MIDI connects Ableton Link to musical devices that support MIDI Clock Sync. Simply join a Link session, connect your MIDI device, and that's it. Your MIDI device is now Link-enabled.

Link to Midi features launch quantization, an incredibly stable clock output, and a fine offset control (±250 ms) to perfectly line up the receiving MIDI device's playback.

Note:
Link to MIDI is only recommended for use with hardware MIDI devices. Connecting to apps is possible, but may lead to a poor user experience due to software challenges in synchronizing to MIDI Clock. Ableton Link fixes this.

Please contact the developers of your favorite apps and ask them to support Ableton Link.
