Sound signal e.g. relaxation tune, generating device for mobile telephone, has background interpretation circuit generating MIDI messages to allow MIDI instruments to generate signal that is constantly varied in pitch and lingering note

摘要

The device has a transmission circuit (4) and an amplifier (10). A background interpretation circuit is induced by background signal data to generate MIDI messages to allow MIDI instruments to generate signal that is constantly varied in pitch, lingering note, repetition note and audibility. The interpretation circuit inhibits the background signal data from exhibiting ascertainable repetition of sequence of the signal. Independent claims are also included for the following: (A) a method for generation of sound signal (B) a computer program for performing the method of generating a sound signal.
