Applied Acoustic Systems has updated its music plug-in, String Studio, bringing the current version to 1.0.1. The update improves plug-in stability in Pro Tools, Logic, and Digital Performer; and corrects abnormal behavior of the Termination model. According to the company String Studio synthesizer swaps the traditional oscillator, filter and envelope pattern for real-life string instrument components. The plug-in uses a new modeling engine that delivers better interaction with picks, bows, hammers, fingers, frets, dampers, and soundboards, said Applied Acoustics. The update is available free from the Web site; new registrations cost $249.
