Digidesign has unveiled Digidesign Structure, its latest RTAS virtual instrument plug-in developed by Advanced INstrument Research (A.I.R) group. The plug-in serves as a professional sampler workstation designed and optimized specifically for Pro Tools, and includes a sample library from EastWest with support for importing SampleCell, EXS24, and Kontakt 2 sample libraries. Structure features a 128-level multitimbral universal sound engine with support for an unlimited number of nestable patches and up to 8-channel interleaved samples. The software directly integrates with the Pro Tools audio engine to support all standard bit depths, sample rates, and surround formats up to 24-bit, 192 kHz, and 7.1 surround sound. Structure also features an integrated multi-effects processing engine with convolution reverb, as well as samples tat users can play back via disk streaming or entirely from memory. Digidesign plans to launch a Structure public beta to a limited number of participants in the near future (pricing was unavailable).
