Hi @carltesta - Link is an open standard dual licensed under GPLv2+ and a proprietary license. It’s therefore integrated into many platforms already. See: Link-enabled music making products | Ableton.
Of course, this also means you can take advantage of the new support for Link with multiple instances of Sonic Pi connected to the same network in addition to any other compatible app or gear.
I’m currently working on a GUI metronome interface which will enable you to send link start and stop messages (there’ll also be equivalent API function calls to do the same from code).
I’m openly developing this stuff through the beta program. Beta1 just really represents a technical preview of the Link support. I definitely recognise that there’s plenty more work to be done before this is really polished and ready for a full release.
