CAMAS, Wash., August 23, 2016 – PLEXSYS Interface Products, Inc., a leading provider of modeling and simulation solutions, announces the release of Comm 4.0. This release represents the latest version of their radio, intercom and communications system modeling software. Version 4.0 increases the fidelity and power of sonomarc Virtual People (Voice Recognition and Synthesized Response) allowing voice-based close control of individual aircraft or a group of wingmen. Debuting in 4.0 is Record and Replay, a capability that allows the review of voice recordings, event flagging and note taking for after-action review and analysis. Linux is fully supported for sonomarc, Instructor Link, Seat Link and Core Connector. The Comm 4.0 release also updates the PLEXComm suite of applications.

“This has been a long time coming,” says Product Manager, Aaron Carlson about Comm 4.0. “We are really excited about this release. We can’t wait to get it out there and see how these new features help the community.” Sales and Business Development Manager, Homer Walden echoed, “continued development of new features for sonomarc and recent improvements including Windows 10 and Linux support, have led us to this major version release.”
