Abstract (en)
[origin: EP0360306A1] In a typical musical tone producing device of a full waveshape readout type, a full waveshape of a musical tone to be produced from the start to the end of sounding or a rise portion and a part of the waveshape following the rise portion of the musical tone is stored in a waveshap memory (12A), and the musical tone is formed by reading out the waveshape from the waveform memory once, or reading out the rise portion once and thereafter reading out the partial waveshape repeatedly. A level parameter memory (18) generates a level information in response to a signal representative of the start of the musical tone, and a level control means (19) modifies the waveshape read out by the waveshape memory (12A) in accordance with the level information.
