Abstract
A method for operating a digital synthesizer type of electronic musical instrument to rapidly make available digital oscillators to produce newly keyed notes even when all digital oscillators are currently active with previous assignments. The method contains a way of maintaining a record of the digital oscillator with the lowest amplitude, and reassigning this lowest amplitude digital oscillator to produce the new note on the rationale that the output of the lowest digital oscillator will be the least missed if an output has to be prematurely curtailed. Beside just a straight amplitude critereon, the method also allows for prioritizing some low amplitude outputs over others to make a more pleasing performance. The invention also includes an apparatus for performing the method.
