Finally got a chance to watch the whole video:
It seems like the elegance and ease of use of the proi channel is moving into the track view which is going to be a time saver big time. Not having to ctrl+arrow to zoom is massive for me. Very Ableton! I really think Cakewalk is on the right track here- making things intuitive and easy without sacrificing power/adaptibility. And the old hotkeys will still be accessible for the grumpy old men.
One thing that I wish sonar had to delete a track is just click and on it and press delete/backspace. Same for pro channel modules- to remove, click on and press delete/backspace. No "do you really wish to delete this?" or anything like that either. If a mistake is made the undo function can clean it up.
But excellent demo again Seth and Brandon- being able to put out LIVE an hour and a half of tightly bound information with no dead air, and humour and taking questions from the audience and leave us still wanting more.... great job!
