Electronic musical instrument
First Claim
1. An electronic musical instrument comprising:
- mode selection means for selecting one of a plurality of modes including sampling and play modes, said mode selection means outputting a mode signal representative of the selected mode;
transducer means for converting a tone into a tone signal representative of said tone;
memory means comprising a plurality of storage areas each having a plurality of addresses;
read/write rate designation means for outputting a first rate signal designating a first rate of access to the addresses of said memory means when said mode signal represents said sampling mode, and for outputting a second rate signal designating a second rate of access to the addresses of said memory means when said mode signal represents said play mode;
storage area designation means for designating one of said plurality of storage areas and for outputting an area signal indicative of the designated storage area;
read/write control means responsive to said mode signal, said first rate signal and said area signal for storing data representing said tone signal into the addresses in said designated storage area only at said first rate when said mode signal represents said sampling mode, and responsive to said mode signal and said second rate signal for reading data from the addresses in said plurality of storage areas at said second rate when said mode signal represents said play mode; and
tone generating means for generating a tone in accordance with the data read from said memory means.

Abstract
An electronic musical instrument of the sampling type is provided. The electronic musical instrument comprises a memory having a plurality of storage areas, and operates in one of full sampling, part sampling, full play and part play modes. Sampling data of waveform of a tone are stored into addresses of all the storage areas in the full sampling mode, and are stored into addresses of one of the storage areas in the part sampling mode. Thus, only one waveform is sampled and stored in the full sampling mode, whereas a plurality of waveforms can be sampled and stored in the part sampling mode. In the full play mode, the whole sampling data are read from the storage areas to form a tone, so that the tone can have a complicated waveform if the sampling data have been stored in the memory in the part sampling mode. In the part play mode, the sampling data are read from the corresponding storage area, so that the tone can be formed from a portion of a waveform if the waveform has been stored in the full sampling mode.
