Abstract: An audio signal processing system including an input circuit for inputting musical instrument digital interface (MIDI) commands in real time over a plurality of channels, a computer including a central processing unit (CPU) supplied with the MIDI commands for simultaneously synthesizing one or more voices for each of the channels in response to the MIDI commands, each of the voices being generated by one or more of a plurality of predefined audio synthesis algorithms executed in software, a random access memory (RAM) for storing digital voice data representative of each of the voices generated by the CPU, an output circuit for audibly reproducing the voices from the digital voice data stored in the RAM, and wherein the CPU, in generating the voices selects the one or more audio synthesis algorithms based on one or more of the following criteria: the external processing demands placed upon the CPU by other operations being performed by the personal computer, a best match, according to predetermined criteria, b

Abstract: An Internet high fidelity audio transmission and compression protocol including a system for representing synthesized music in a relatively small file as compared to digital recording. The protocol includes a method for streaming the transmission of a music data file from a Server-Composer computer such that the music can begin being played back as soon as the file begins to arrive at a Client-Player computer. The system includes a graduated resolution improvement feature which allows the music to be recreated exactly as originally composed as the necessary wavetable data is downloading in the background and the music continues to play in the foreground.
