Abstract:
A tone generating device comprising: a waveform memory having stored therein waveform data of a plural-cycle waveform; a pitch designating section that designates a pitch of a tone to be generated; a control information generating section that generates control information specifying, in a time function, an address location of the waveform data to be read out from said waveform memory; an address generating section that generates a read address advancing at a rate corresponding to the pitch designated by said pitch designating section; a control unit that makes a comparison between the address location specified by the control information and a location of the read address generated by said address generating section and controls shifting of the read address in accordance with a result of the comparison; and a section that reads out the waveform data on the basis of the read address controlled by said control unit.
