Holy crap. Usually this version comes as a pack-in when you buy a keyboard or MIDI controller. But now it’s free for everyone (of course, you can also now export directly to Soundcloud.)
If you’re signed up for Soundcloud’s newsletter, you’ll get a download code by mid-April. You can also claim it from Ableton’s site, at least until May 31st.

This is potentially huge. Make music!
