Very easy installation - trouble-free - (Sonar Update 3)
The software is rather simple to understand and configure according to his needs.
The paper manual is not bad (but using the PC is also useful for specific items)

SUITABILITY/PERFORMANCE

Used with a sound card RME Fireface 400 latency ... (?) Zero (Processor E6600 / 2 GB mem.)
No particular problem, using Plug VSTI - DXI carefree ...

OVERALL OPINION

Used since its release after ... Sonar 3.
+ The simplicity, efficiency, not "factories" and that's very important!
The - some (very rare) crash, but one that bump on PC and told me never to have had ....
I do not know Cubase from a distance, probably a very good software too - but I like less presentation and then it is more expensive! (The rest I do not allow me to judge)
Of course, these software are not given ... but when you love - it's all about choice ...
