BIRTH STORY OF VOIBOW
~Outline of works~
We are developing electronic musical instruments that can be easily played with full-fledged tones for an era in which anyone can become a musician. It is a mathematical model method based on complex systems and has the following features.
(1) The physical phenomena of acoustic instruments are modeled, and even the aperiodic fluctuations are realistic. No wave sample.
(2) Liberation from the physical constraints of acoustic instruments (difficulty of playing/structural limitations).
(3) By perturbing the mathematical model with your voice, you can make sounds that match your voice. Wind instruments only.
