Sonar 5 adds an arsenal of responsive instruments, more effects, and powerful editing tools including Roland® V-Vocal™ VariPhrase technology. These features are complemented by a double precision floating point engine that delivers dramatic increases in dynamic range. SONAR 5 features a 64-bit audio engine, which offers seamless audio quality, which is also accessible even on 32-bit computers. Sonar 5 Studio Edition is built upon the same core engine and feature set of SONAR 5 Producer Edition, but doesn't include new plug-ins and special functions that the Producer Edition includes.
