摘要： A musical sound control apparatus (1) includes a slider (17a), a CPU (11) and a recording ring buffer (13a). The slider (17a) enables scratching in both directions. The CPU (11) plays back musical sound data being sequentially supplied. The recording ring buffer (13a) rapidly stores, in response to emit a sound of the musical sound data being supplied, the musical sound data. The CPU (11), in a case of a scratch operation being performed on the slider (17a), controls so as to read out and playback the musical sound data stored in the recording ring buffer (13a) in place of the musical sound data being supplied, based on a direction and operation speed of the scratch operation.

摘要： During reproduction of drum-part performance tones with a predetermined performance pattern, comprising a combination of a plurality of drum tone colors, based on automatic performance style data including at least performance pattern data associated with a drum kit defining a combination of the plurality of drum tone colors, a drum kit editing section replaces any one or more of the drum tone colors, defined in the drum kit, with one or more other drum tone colors. Thus, even during an automatic accompaniment, a user can readily replace any one or more of the drum tone colors, defined in the drum kit allocated to the drum part, with one or more other drum tone colors while promptly checking an automatic accompaniment having the other drum tone colors reflected therein.

摘要： From a storage device storing waveform sample data sampled at a given sampling rate, the waveform sample data are read out asynchronously with the given sampling rate and temporarily stored in an input buffer. The thus-stored waveform sample data are read out from the input buffer and converted to an inner sampling rate selected from among a plurality of predetermined inner sampling rates. Predetermined arithmetic processing is performed on the waveform sample data converted to the selected inner sampling rate. Then, the waveform sample data having undergone the predetermined arithmetic processing are converted to a predetermined output sampling rate and written into an output buffer. The thus-written waveform sample data are then sequentially read out at an sampling frequency corresponding to the output sampling rate, to thereby generate tone data in accordance with the output sampling frequency.

摘要： A portable telephone having music playback functions has a first storage for storing music data of plural musical tunes and a second storage (namely, a cache memory) for storing at least one musical tune to be reproduced. A musical tune that may be likely to be reproduced is selected from among plural musical tunes in accordance with prescribed rules, so that the music data of the selected musical tune are precedently transferred from the first storage to the second storage to enable smooth reproduction in response to an incoming call whose telephone number specifies the selected musical tune.
