The VMS Arranger is our tool for creating arrangements and is integrated into the OVC-3D. It allows the arranger to set placements and assign the instruments that play there. It integrates with the synthesizer to auto-generate icons for each scene element, so that the arrangement is displayed as a graphical storyboard. The control system is hierarchical, so that multiple instruments and placements can be viewed as a single object, which can then be opened to display the individual elements.
The time axis can be static or dynamic. When working with a prerecorded audio composition, the timing points are fixed: the arranger knows the exact time that each placement should occur in the composition. When performing live, the arrangement has to adapt not just to variations in tempo, but to spontaneous changes, such as when the length of a solo varies or the band segues into a different composition.
