Research paper thumbnail of Current source circuit with complementary current mirrors

Research paper thumbnail of A Novel System for Music Synthesis Using A Digital Sound Processor IC

IEEE Transactions on Consumer Electronics, 1985

A 16-channel, polyphonic and polytimbric, fully digital sound processor IC for music synthesis is... more A 16-channel, polyphonic and polytimbric, fully digital sound processor IC for music synthesis is described. It is microprocessor-controlled and the coded music information is resident in an external memory. The analog filters and attenuators, typical of traditional sound generation, can be completely eliminated. The major advantages are drastic reduction of board spacing, no need of any kind of calibration, sound characteristic stability with time and from set to set. Applications include classic electronic organs, keyboard synthesizers and personal computer musical peripherals.
