A workstation system produces a display presentation of a selected
performance composition (e.g., a musical composition) responsive to
composition data and responsive to one or both of input variables and a
selected operating mode. The workstation can communicate with one or more
external devices, such as other workstations, etc. The display system
provides for selection of original compositions, creation of derivative
compositions, distribution of compositions, monitoring of each
performer's performance, group virtual performances, and for local and
distributed retrieval and editing, which for music includes things such
as changing keys, pitch, tempo, and other parameters. The musical
composition's transformation can be performed locally or at the central
or distributed music database. The musical composition data can be
transposed via a controller, and can be transmitted to a plurality of the
individual workstations that then display the musical composition. In one
embodiment, a display system for use by a plurality of users provides a
plurality of display presentations of a selected musical composition. The
system is comprised of a plurality of individual workstations, each
workstation comprising a communication interface providing for
communications with the respective workstation of music data
representative of the selected musical composition, memory for locally
storing the data responsive to the communications interface, and a
display apparatus provides a local visual display presentation
representative of the selected musical composition responsive to the
stored data. The system further provides for synchronizing the
presentation on the plurality of local visual display presentations of
the selected musical composition.
