I can only speak for myself here. but im in my late 40's.
It seems Sonar itself was aimed at users in their later 30's and up.
I didn't see any youth joining Cakewalk as their main DAW. I watch a lot of You tube videos and just don't see the youth using Sonar. Im guessing the ratio is low. 15% youth to 85% older musicians/engineers/producers like myself.
I enjoyed Sonar very much and I still do but I think the downfall may have been targeting older customers and not injecting enough youth in to the program. And another negative would be not listening to its users enough but instead making major DAW choices by panel committee. How many times have we (as users) asked for features only to go on deaf ears until a year later when Cakewalk says; "That might be a good idea".
A great example would be color schemes. We asked for color schemes back in 2011. We only got a theme editor in 2016.
I saw a disconnect from its users and I still see that disconnect now as we are all patiently waiting for an off line authorization and we still haven't heard from Cakewalk in over 3 weeks. I understand legal matters, but its just ridicules.
I am still a huge Sonar Fanboy but even I know the difference between what it is... and what it isn't.
