Abstract: A virtual instrument for real-time musical generation includes a musical rule set unit for defining musical rules, a time constrained pitch generator for synchronizing generated music, an audio generator for generating audio signals, wherein the rule definitions describe real-time morphable music parameters, and said morphable music parameters are controllable directly by the real-time control signal. With this virtual instrument, the user can create new musical content in a simple and interactive way regardless of the level of musical training obtained before using the instrument.

Abstract: A real-time music generation engine for an interactive system includes a Musical Rule Set (MRS AND/OR CA AND/OR PCU) unit configured to combine predefined composer input with a real-time control signal into a music signal; a Constructor Automaton (CA) configured to generate a fluid piece of music based on rule definitions defined by the predefined composer input within the MRS AND/OR CA AND/OR PCU unit by musical handlers; and a Performance Cluster Unit (PCU) configured to convert the fluid piece of music from the CA into a corresponding music control signal for real-time playback by the interactive system.
