Abstract: The waveform generation device can reproduce waveform data of various sounds stored in a memory at a reproduction velocity of reproducing waveforms at a real time and is provided with a storage system for storing the waveform data of a waveform sequence with the plural waveforms arrange in time series, a pitch information input system for entering pitch information, a time information generating system for generating time information changing at a velocity having no connection with the pitch to be reproduced, and a reproduction means for reproducing the waveform data to be read at the reproduction pitch waveform data of the pitch information input system, including a reading system for reading the waveform data from the storage system at a desired reading velocity corresponding to the time information and the pitch information yet having no connection with the velocity of changing the time information.

Abstract: A device and method for reproducing musical sounds is disclosed. Musical sounds and voices are stored and reproduced with user-definable timing and pitch, with the timing and pitch being independently controllable in real time. Musical sounds are stored in waveform memory, and pitch and timing information may be received in real time. The stored musical sounds and voices are then reproduced in accordance with the received pitch and timing information. The reproduction of stored musical sounds can also be stopped and resumed at user-definable marks.
