I got S1 professional as an upgrade from Artist (that was a throw in on an old interface) on one of these advertised deals, for $100 specifically for that feature (that and I needed a cross Mac/Windows platform for stuff I do at my church), but I use Sonar pretty much exclusively for everything else. You can sort of do this in Sonar, but it's a lot more painstaking. One thing I'd like to see Sonar pickup that S1 has (and you did a great NAMM presentation on, that's on your YT site) is album mastering and ability to throw in tracks and order them and reorder them, etc. With the decline of physical media and an emphasis towards singles instead of albums, I'm finding this less and less of an issue with each passing year. The biggest limitation in Sonar is CD production (e.g., CD text and such). The tool has been specially developed, designed and optimized to meet the highest professional standards with a fully customized interface. If you're doing multi-point editing for broadcast you'll need something like Sequoia, but that's major $$$ for a capability you likely won't use for mastering music. Samplitude Pro X3 offers numerous innovative functions and advanced performance features. Throw it in a channel, create a screen set that's optimized for mastering, and you can take care of most mastering situations. instruments, and tools bundled with Samplitude, to create the most powerful DAW. Ozone 5 costs $249 and has any "missing" mastering plug-ins and diagnostics tools. Get the lowest price on the Magix Samplitude Pro X6 Suite Software. Anderton Samplitude is a fine program, but I've been doing more and more mastering in Sonar.
