When Propellerhead Reason 1.0 was released, the idea of replacing hardware synths with software was still hard for many people to swallow. Reason changed that, as the breakthrough app that popularized the “soft synth workstation” category. Now soft synths are everywhere, and skeptics might wonder if Reason can keep up with increasingly feature-laden applications like Cakewalk Project5. You might think features related to instrument routing and MIDI controller assignments aren’t especially pulse-quickening, for instance. You’d be wrong: These are exactly the features that make Reason more fun to play than ever.
