Abstract
The present synthesizer includes functionality for changing over from a current note to the following notes that results in natural and expressive combinations and transitions. The method of the present invention incorporates an delay (actual, functional, or look ahead) between receiving control data inputs and generating an output sound. This period of delay is used to modify how notes will be played according to control data inputs for later notes. The input to the synthesizer is typically a time-varying MIDI stream, which may be provided by a musician or a MIDI sequencer from stored data. An actual delay occurs when the synthesizer receives a MIDI stream and buffers it while looking ahead for changeovers between notes. A functional delay occurs in a system in which the synthesizer has knowledge of note changeovers ahead of time. A look ahead delay occurs when the synthesizer queries the sequencer for information about the stored sequence ahead of when the synthesizer needs to generate the output for the sequence.
