ABSTRACT:
A music synthesizer is disclosed which includes a keyboard for entering musical notes to be synthesized into the music synthesizer. The music synthesizer also includes a rhythm control arrangement, such as push buttons, for selecting prestored repetitive rhythm pattern tempos to be synthesized into the music synthesizer. A single microprocessor computer is provided which processes and establishes priority of signals from the keyboard and the rhythm control buttons for generating signals indicative of the frequency and amplitude of the musical note to be synthesized and for generating musical instrument signals and combining them into the rhythm pattern to be synthesized. A tone generator is provided which is controlled by the computer for generating a squarewave signal having the frequency of the musical note to be synthesized. A tone blender and shaper is provided which includes a first wave shaping circuit which receives signals from the tone generator and from the computer to form a first signal having a first predetermined wave shape indicative of the musical note to be synthesized. The tone blender and shaper includes a second wave shaping circuit which receives signals from the computer to form a second signal having a second predetermined wave shape which is indicative of a drum beat of predetermined frequency which forms a portion of the rhythm pattern to be synthesized. The tone blender and shaper includes a third wave shaping circuit which receives signals from the computer to form a third signal having a third predetermined wave shape indicative of a snare drum sound which forms a portion of the rhythm pattern to be synthesized. The tone blender and shaper also includes a circuit for combining the first, second and third signals into a composite signal. The composite signal is then amplified and applied to a speaker to form sound waves which comprise the preselected repetitive rhythm pattern and the musical notes determined by operation of the keyboard.
