[edit] Overview

The Roland VariOS is a rack-mounted open-ended variable system module, released by Roland in 2003. It is essentially a production environment with audio editing and sample playback, based on the technology from the oft-overlooked VP-9000 Variprhase Processor. It is possible to independently manipulate the pitch, time and formant of a sample, add effects and even build complete audio-based arrangements—all in a realtime environment and without CPU drain. In addition, it will emulate analogue synthesisers such as the Roland Jupiter 8.

While the VariOS can operate as a stand-alone tool, it also works alongside digital audio sequencers using MIDI clock and MTC sync. V-Producer arrangements can also be saved as a Standard MIDI File, and processed audio files can be exported in .WAV or AIFF format for use in other editors and software.

[edit] Expansion Cards

Two expansion cards were released for the VariOS, the VC-1 which emulates a Roland D-50, and the VC-2 which allowed vocal processing with an external microphone, with effects such as a vocoder and choir. Much to the disappointment of VariOS owners who spent considerable amounts of money (albeit on a powerful unit), it appears Roland have no plans to release any future expansion cards. Furthermore, it appears the VC-2 is now out of production, with various sources claiming that Roland made a set number of cards in an "estimation" of demand.
