Title: Kouichi Kashiwazaki: Innovator in Tone Generation Technology

Introduction

Kouichi Kashiwazaki is a notable inventor based in Hamamatsu, Japan. He has made significant contributions to the field of musical tone generation, holding three patents that showcase his innovative approach to sound technology. His work primarily focuses on enhancing the capabilities of tone generation apparatuses.

Latest Patents

Kashiwazaki's latest patents include a tone generation apparatus and a musical tone signal generating apparatus. The tone generation apparatus responds to a note-on instruction by utilizing a CPU to assign a tone generating unit with two channels. This system allows for the setting of tone color control data, which includes parameters common to both channels. The CPU initiates tone generation, leading to the accumulation of a frequency number that generates a progressive phase shared by both channels. Additionally, the waveform readout section retrieves left and right channel waveform data based on the phase and selection information, ensuring that the tone characteristics are controlled by a common parameter.

The musical tone signal generating apparatus involves a CPU supplying parameters to a tone generator with multiple channels. This system designates specific channels for generating musical tone signals based on defined musical tone information. The tone generator features a reservation circuit that allows designated channels to start generating signals when their current volume levels are below a certain threshold.
