Started with Sonar 2, and continued through each version of Sonar until "the end".
Then began trying different DAW's out will Cakewalk went into limbo.
Came back to Cakewalk, but don't use it as much nowadays.
Use ProTools for a while, but it requires more RAM and CPU than anything else so gave up with it.
Ableton Live was very good and stable, but just wasn't for me.
I still use Adobe Audition for pure audio and some mastering.
Reaper is my main DAW at the moment.
