<p>A musical sound generator is provided using a combination of software processing and hardware processing. A sub CPU (210) generates note data based on score data (340). A main CPU (110) refers to a sound source file to convert note data and generate PCM data. A sound processor (220) converts note data using a sound synthesizer circuit (221) to generate PCM data. A D/A converter (222) converts two PCM data into analog voltage signals. A speaker (300) outputs sound in response to the voltage signals.</p> |
