It’s reasonable to suggest that Sonar is the most popular PC-only DAW in the world. A couple of years back, it was given an almighty overhaul and rebranded as Sonar X1. This heralded the arrival of a much cleaner and clutter-free GUI, a powerful built-in channel strip (the ProChannel) and many more features that greatly improve the workflow.
The most recent version is Sonar X3 - the first to be released since Cakewalk was acquired by Gibson - which refines the software to deliver smoother, faster performance and some well-implemented new features (the comping facility and Melodyne integration are particularly noteworthy). It provides confirmation, if we needed it, that Sonar is still keeping pace with the pack.45 Stars
