Musical effects apparatus and tone control process for a musical instrument

摘要

In an automated system for learning to play a musical instrument, music data and tone control data for a musical composition of an exemplary musical instrument is stored in machine readable form. An audio signal generated by a musical instrument being played, corresponding to the exemplary musical instrument, is inputted through a musical effects apparatus wherein the musical tone of the musical instrument being played is mixed with the stored music data. The musical effects apparatus is utilized, under digital control, to match the musical tone of the musical instrument being played with that of the exemplary musical instrument. More particularly, the music data and tone control data of the musical composition are stored on a conventional CD- ROM. The tone control data is utilized to create control parameters which can be used to control one or more electronic effects devices in an automated fashion. The stored parameters include control data utilized to set the values of one or more digitally-controlled programmable resistor networks capable of conditioning the input audio signal under digital control, without first converting the conditioned audio signal to a digital signal.
