I own both SAWStudio and Software Audio Console and both applications are "second-to-none".
Pricing has been reduced significantly on SAWStudio. Check out the Web site: RML Studios
PS: Though some consider it significant, I am really not at all concerned with the apps being 32-bit. If you truly understand how great the quality is of SAWStudio's internal processing - then the type of app is really of no concern.
Mr. Lentini, the developer, does have a very specific manner in which he works with his applications. But once you get a feel for his methodology - in the end, this methodology really does make sense.
