Hi
Anybody using Ableton?  I've got the Lite 9 version which came with a midi controller.  I'm learning my way round this as well as using Cubase Elements. (I'll keep my copy of Sonar too)
Re Ableton. If I ever want to upgrade, I wondered if there is a massive difference between Standard and Suite and whether Standard is enough for the average user. 
 
 

I have lite version too. Love how it handles samples

It's an expensive DAW.   Best on a large screen.  No VST3 support.  The piano roll aint no Sonar. The Suite version is the most overpriced DAW on the market.
 
It's still a great DAW but is so different from Sonar.

I have Live 9 and use it for sketching out ideas, but as kitekrazy1 said it doesn't support vst3, so I don't see it replacing Sonar for me.
