Abstract:
1. A musical performance apparatus comprising: a sample value storing portion storing sample values, which are obtained by sampling a plurality of tones, that indicate waveforms of the plurality of tones so that the sampling periods of the sample values are associated with addresses; and a reproducing portion that sequentially reads out the sample values, and reproduces the tones so that a section of each tone are repeatedly reproducible, wherein a first tone and a second tone, among the plurality of tones, are formed of a frequency component included in a certain high frequency band so that each of the first tone and the second tone will correspond to a section of a control tone corresponding to a control signal for controlling an external apparatus, and wherein the reproducing portion has: a reproduction starting portion that designates a first loop start address and a first loop end address, at which a sample value of a start of the section of the first tone is stored and at which a sample value of an end of the section of the first tone is stored, respectively, and starts reproduction of the first tone; a loop reproduction section changing portion that changes the loop start address and the loop end address designated by the reproduction starting portion to a second start address at which a sample value of a start of the section of the second tone is stored and a second end address at which a sample value of an end of the section of the second tone is stored, when a reading address for reading the sample values of the first tone reaches a certain address, and starts reproduction of the section of the second tone so that the reproduction of the second tone starts at a position situated in the section of the second tone and corresponding to an address obtained by adding an offset address indicative of an offset amount between the first loop start address and the certain address to the second start address.
