摘要： A tone signal generating apparatus comprises a waveform memory (14) in which a plurality of waveform data representing different waveforms but corresponding to a same tone name are stored. These different waveform data are sequentially read from the memory (14) and are supplied to a digital low-pass filter (28) which comprises a delay circuit (33) and a multiplier (31) connected to each other to form a feedback loop. The low-pass filter (28) smoothes abrupt variation of the waveform data and outputs a smoothed waveform data thereby interpolating the different waveforms. A tone signal is produced in accordance with this smoothed waveform data.

摘要： 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 waveshape memory (12), 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 digital filter (14) is introduced following the waveshape memory (12) in this tone-producing device. The filter characteristics are determined in accordance with a tone color change parameter such as the key touch or the tone pitch of the musical tone, thereby realizing a tone color change of the muscial tone. Further, in order to realize timewise change of tone color of the musical tone, circuit which lets the tone color change parameter vary with time is proposed.
摘要翻译：从音乐的开始到结束产生的音调的完整波形或音乐的上升部分之后的上升部分和波形的一部分被存储在波形存储器（12）中，并且音调通过从波形存储器读出波形一次，或者一次读出上升部分，然后重复地读出部分波形而形成。在该音调产生装置中的波形存储器（12）之后引入数字滤波器（14）。根据音调变化参数（例如按键触摸或音调的音调）来确定滤波器特性，从而实现乐音的音调变化。此外，为了实现音调的色调的时间变化，提出了使音色变化参数随时间变化的电路。

摘要： In one embodiment, the circuit includes a first order FIR highpass filter (56) that is placed between a modulation phase increment oscillator (54) and a carrier phase increment oscillator (60). The invention may also include waveshaping circuits, adders, multipliers, time division multiplexing, and other types of filters. Another embodiment of the invention provides a music synthesis method where a modulation phase increment is multiplied by a modulation index to produce a modulation signal. That modulation signal is then filtered and added to a carrier phase increment. Finally, that sum is multiplied by an amplitude envelope to produce a signal representing a musical sound. The method may include using a first order FIR highpass filter, waveshaping of both sinusoidal and non-sinusoidal waveforms, additional multiplying and time division multiplexing. The invention also includes self-modulation and cascading.
