I am definitely not disputing any of that in any way. As someone who also has only every used SONAR, I certainly did not demo S3 because I was bored (3 months ago now). I did not buy S3, but the arrangement/scratch pad portions are definitely tempting. Short term I keep arranging to "nuts and bolts" only, which is easily manageable, but cringe at the thought of chopping/swapping sections in a final mix.
My original comment came from step sequencer issues I was having 2 years ago that cause me to get Geist. At that time I felt there should be no reason to have to (Cakewalk's roots are in MIDI, so should be the king of MIDI IMO). But in hindsight the time-pressure for "necessity" was actually good for me (since 2 years later, the issues that drove me to buy Geist still exist).
I guess was meant more as a dose of reality. Not that the issue is not huge (it is), but when will users actually see it?
