…they suddenly appeared - ten channels! - in a project I’m working on; where do they come from?!? 
I only have an Ableton Live 12 lite version on my MacBook…
Thanx,

Hi,
Rewire technology is not supported for many many years, as the Rewire standard vendor stopped the support.
Thank you @Martin.Jirsak ,
I know it well, as I own both Cubase and Live 10 (this one I only use on my old MacMini) in fact my question was about where the rewire tracks could come from, I was kind of surprised to see them appear…

Hi,
Only a ReWire device can create ReWire channels.
Is it a fresh project or an old one?
Hi @Martin.Jirsak,
Sorry for delay in getting back to you…
It’s a new project, on my MacBook Pro M1 Max, where I nevere installed Live 10 on (I only have Live 12 lite, that I opened a couple of time…)
