I strongly assume that the people here who are familiar with ReWire know what ReWire was intended for.
“Link, on the other hand, is designed to keep multiple devices in time over a local network without a designated host/leader. Devices can start and stop freely or change the tempo. Link also doesn’t provide audio or MIDI buses.”
→ That’s precisely the point here; ReWire was only mentioned (with all its limitations) due to a lack of alternatives.
I also used it back then to use Reason as a sound module in Cubase (I was just starting out with Reason and had so many sounds).
“If your objective is to sync up Ableton Live to Cubase, for example, I don’t see how Link is much of a benefit compared to something more traditional like MIDI Clock or MTC, for example.”
→ Ableton Link – the advantages over MIDI Clock
No master/slave constraint
All participants have equal rights. Any device can change the tempo, and all others follow immediately.
Very stable timing (less jitter)
Link works beat-based over a network (LAN/WLAN) instead of with individual clock ticks → feels musically more “solid” than MIDI Clock.
Plug & Play
No complicated routing, no clock settings, no channels. Link on → it works.
Dynamic joining and leaving
Devices or apps can join or leave at any time without everything falling apart.
Network-compatible
Works over Wi-Fi or Ethernet, even across multiple computers, tablets, and smartphones.
Shared tempo and phase
Not only BPM, but also the musical position (bars/beats) remains synchronized.
Anyone with a compatible DAW on a laptop, a (not too old) MPC, an iPad, etc., can immediately join a session and even change the tempo.
These are the advantages users here would appreciate, which is why this thread exists.
To stream audio and MIDI from DAW to DAW, I use (the already mentioned “Blue Cat’s Connector”). With it, you can fully utilize the connected DAWs (unlike with ReWire). I used it to stream audio from my Mac Mini with Ableton Live to a computer with Cubase via network cable, and then record in Cubase.
It would have been fantastic if Cubase were also Ableton Link compatible.
