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.
