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 VariPhrase 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.
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.
