Device and method for reproduction of sounds with independently variable duration and pitch

A waveform generation device comprising:

• a storage means for storing waveform data of a waveform sequence with plural waveforms arranged in time series;
• a reproducing velocity information input means for entering reproducing velocity information representing a reproducing velocity of the waveform data;
• a pitch information input means for entering pitch information concerning a pitch;
• and
• a reproduction means for reproducing a waveform data of the storage means at a reproducing velocity corresponding to said reproducing velocity information and at a pitch corresponding to said pitch information;
• wherein:
• said storage means stores the waveform data and mark information indicating one or more positions of the waveform sequence on a time axis;
• and
• said reproduction means has a first control means for performing a control for controlling a movement of a reproduction position of the waveform data when the reproduction position of the waveform data has reached a position indicating the mark information.
