But... like other commenters - there it stops, and I'm just not quite sure why.
The audience is probably me. I'm an avid Ableton user - I pay a bloody fortune for it, I upgrade it every year, I am happy to support their development because it's an insanely - insanely - good piece of software that does everything I need it to do. I'm also now completely embedded in the clip view, so going back to a linear view just isn't a possibility for me.
More to the point though - this clearly isn't aimed at people who know nothing about what they're doing. It's very non-amateur and clearly very, very powerful. But at the same time it isn't aimed at me, either - as someone who does know what they're doing, I'm thinking "um, VSTs?" or "clip view?" or "live performance / latency issues?" or whatever.
So... who is the audience? Maybe there is a middle ground of people who don't have the means to fork out for a good desktop DAW. Maybe teenagers who are wanting to learn the principles without the spend. Maybe because it'd be very cool for collaborating? I just don't know.
Nonetheless, it's an insane demonstration of what can be done in a browser these days and for that I massively doff my cap - amazing work!
