I don't think the v7 demo provides everything, as I haven't checked that, but as for version 7 on a whole, there's a lot to like.
The big one is clip launching. Select
B on your keys. Just get a feel for that. People well versed with Ableton Live will point out the launcher's lack of being full featured (comparatively) while others will enjoy some of the uniqueness of how it's implemented. Personally, I like the horizontal 1:1 relationship between the arrangement view, the launcher, and the scratchpad.
Version Seven now includes all of the add on features, that used to cost extra, such as the Orchestral library, Presonus Editor, Batch converter, and well.... Just about everything.
New are the stem separator, global transpose, and more.
Version Seven as I see it is largely the single biggest "throw in" of any Studio One version yet. I'm not saying best, but it is undoubtedly the biggest add on the goodies version to date.
But don't take my word for it. Here's a Sound on Sound review. It saves us a lot of chitter-chatter. ; )
You get the idea .....
Enjoy!
