Method for making electronic tones close to acoustic tones, recording system for the acoustic tones, tone generating system for the electronic tones

#This invention relates to recording and electronic tone generating technologies and, more particularly, to a method for making electronic tones close in impression to acoustic tones, a recording system for producing pieces of waveform data from the acoustic tones and a tone generating system for reproducing the electronic tones from the pieces of waveform data.

#Musical instruments are broken down into two categories, i.e., acoustic musical instruments and electronic musical instruments. These two sorts of musical instruments have their merits and demerits. The acoustic musical instruments are popular to both old and young. The acoustic tones are familiar to most music lovers, and are rich. However, several acoustic musical instruments are bulky, and the players feel it difficult to produce faint tones throughout a piece of music. When a city dweller plays a piece of music on an acoustic musical instrument, he or she is careful of the tones, because the neighborhood sometimes makes a complaint against him or her.

#On the other hand, the electronic musical instruments are usually less bulky rather than corresponding acoustic musical instruments. Players easily play pieces of music at extremely small loudness, because the players can control the amplifiers between a large gain to a small gain. If the players hear their performance through headphones, they do not need to be afraid for the neighborhood. However, the electronic tones are not so rich as the acoustic tones.

#The features and advantages of the method, recording system and tone generating system will be more clearly understood from the following description taken in conjunction with the accompanying drawings, in which

#In the following description, term “front” is indicative of a position closer to a player than a position modified with “rear”, and a direction passing through a front position and the corresponding rear position is referred to as “longitudinal direction”. Term “lateral direction” is indicative of the direction crossing the lateral direction at right angle.

#A series of pieces of waveform data is representative of a tone. When a tone is recorded at plural recording points, plural series of pieces of waveform data are representative of the tone, and form in combination a set of waveform data series. Tones sequentially produced along a scale are represented by plural sets of waveform data series, and the plural sets of waveform data series form a group of waveform data sets.
