Abstract:
1. A tone generation processing apparatus comprising: a plurality of tone generator devices; a plurality of waveform data memories corresponding to said plurality of tone generator devices and exclusively usable by corresponding ones of said plurality of tone generator devices, wherein each of said tone generator devices uses waveform data, stored in the waveform data memory exclusively usable thereby, to generate a waveform signal of a tone indicated by given event information; an event reception section that receives event information indicating a tone to be generated; a table that determines how to divide, for each of tone colors, an entire pitch range into a plurality of pitch ranges in association with an individual tone color and defines, among said plurality of tone generator devices, a tone generator device to be used for each of combinations of the individual tone color and the pitch ranges associated therewith; a tone generator selection section that selects, from among said plurality of tone generator devices, a tone generator device to be used for generating the tone corresponding to the event information received by said event reception section, wherein said tone generator selection section includes a pitch range identifying section that identifies a pitch range which said tone corresponding to the event information belongs to by referring to said table on the basis of a selected tone color and a pitch of said tone corresponding to the event information, and a tone generator device determining section that determines a tone generator device to be used for generating the tone corresponding to the event information by referring to said table in accordance with a combination of the selected tone color and the identified pitch range; and a delivery section that delivers the received event information to said tone generator device selected by said tone generator selection section so that a waveform signal of the tone indicated by the received event information is generated by the selected tone generator device.
