Watching things unfold since the day that Gibson pulled the plug one thing really stands out and that is:
 
There are many versions of Sonar that are being missed. 
 
I upgraded to Platinum 18 months ago with Life Time Updates when I got a new PC and that is the version that is now my reference for discussions here and was/is (probably) my favourite Sonar. This assumes that I ignore CAL and StudioWare bot of which I thought were great and both of which ended up being neglected.
 
I spent a lot of time on 8, I regret not upgrading to 8.5 probably as much as I regret upgrading to X1.
 
So my question to everyone else is which is the version of Sonar that you are going to miss?
 
And for those on older versions, what made you stick with that version rather than upgrading?

Splatinum 10-2017

Which Version Of Cakewalk/Sonar Were You Running On THAT Day?

 
The last one published.

BTW, I'm still running that one and the world has not stopped and I'm still making music (if you want to call it that).
 

Version 23.10.0 Build 14 [2017.10]

I had Sonar Professional Steam Edition up to and including the 2016 version, so whatever was the final update included in that.

Sonar Platinum Version 10 2017 is what I have and only found out about the shut down by chance while looking to see if there were going to be a deals for Thanksgiving.
