I am surprised such thread does not exist yet (or have I missed it?)
Since that is primary current product of the new "Sonar technology" owner, I guess we can expect at least an attempt of fusion in the future. I do not exclude that Sonar is planned as a "standalone windows app" in the BandLab framework.
I do not have sufficiently powerful mobile devices, but I had a look at "Web DAW" app. And I must admit, I was positively surprised. Chrome only, but it really works. Looks nice, render fast and does not produce errors.
The only comment: I have not found any FAQ how to bring the latency down to usable level (I can play slowly peaces on MIDI keyboard with default settings, but that is too inconvenient).
Have other already tried it as well?
