FWIW... I was able to use Sonar (X1) as a simple tracker/mixer within a couple hours of having it installed (but I did have some hardware issues that had to be sorted out to avoid clicks and dropouts).
The basics are not that hard to figure out IF you go through the tuts.
Insert a track(s), set your inputs, arm the track(s), press record.
Move the faders on the console to balance the levels of what you've recorded.
Export from the master (which all the track outputs default to).
It's actually way simpler than the old hardware multi trackers. No ping ponging, reading bizarro manuals that have been translated from Japanese to English, deciphering strange routing schemes, hooking up to external tape decks for export, etc... and getting much better results than the hissy/craptacular cassette tape output of those old units.
To go deeper? Hellz ya. It's way more complicated... but it's a PRO piece of software.
It's not supposed to be "easy". It's supposed to do WTF you need it to. The "easy" factor is there as much as it can be but if you dumb it down too much it will no longer be able to accomplish the "pro" level results.
And yeah... I do think some things could be easier/more straightforward but I'm not the one coding this behemoth nor can I anticipate the extremely broad needs of Cake's user base.
I also don't expect to install a pro video editing program and immediately become Coppola overnight either.
This sh*t is hard and requires patience/study/work. That's just the way it is. No DAW worth its salt is going to be any different.
Cheers.
