Tascam has announced GigaStudio 4. This new version supports 64-bit operating systems like Windows XP64 and Windows Vista 64, allowing users to access up to 128 gigabytes of RAM for loading massive sample libraries and compositional templates. GigaStudio 4 also hosts VSTi and GVI virtual instruments, loading or stacking instruments alongside GigaStudio instrument libraries. When hosted in GigaStudio 4, virtual instruments based on Tascam's GVI gain the advantages of kernel-level processing, offering lower latency than other host applications. Hundreds of enhancements have been made from GigaStudio 3 such as an all-new QuickSound database tool, additions to the QuickEdit interface and many user interface improvements.

"GigaStudio remains the industry standard for producers, composers and musicians who demand the best," remarked Product Development Manager Jim Bailey. "While many customers enjoy the ease-of-use and single-computer workflow of GVI, GigaStudio 4 offers the high-end user the ultimate solution for a dedicated instrument workstation. GigaStudio has enjoyed an almost exclusive use by top-grossing film composers, the most demanding sampler users, because of its reliability, sound quality and performance. GigaStudio 4 continues that tradition."

GigaStudio 4 builds on the features of GigaStudio 3, including unlimited polyphony, 96kHz/24-bit sample support, 128 MIDI channel playback and embedded GigaPulse convolution reverb. The iMIDI rule programming includes legato mode, round-robin, alternation, portamento, dynamic expression filters and more to add realism to sampled performances. The new version supports Windows XP and Windows Vista (32 and 64-bit versions).
