摘要： A lead tone is generated on the basis of an input tone signal. Meanwhile, a specific pitch of the input tone signal is sequentially detected, from which is detected a normalized pitch corresponding to any one of the musical pitch names. Then, difference information is obtained which pertains to a difference between the specific pitch and the normalized pitch, and a pitch having a given pitch interval from the normalized pitch is determined as a target pitch of a tone signal to be generated. Then, a harmony tone is generated which has a pitch obtained by modulating the target pitch in accordance with the difference information.

摘要： Specific pitch of an input tone signal is sequentially detected, and a normalized pitch corresponding to a pitch name is sequentially detected on the basis of the specific pitch. It is determined whether there has been a variation in the detected pitch. Lead tone (first tone signal) is generated on the basis of the input tone signal, and a harmony tone (second tone signal) is generated on the basis of the detected pitch. When it is determined that there has been a variation in the pitch, processing waits until a predetermined time passes, and control is performed to change a pitch of the second tone signal if a pitch detected immediately before the variation and a current detected pitch are determined to be different from each other upon the passage of the predetermined time.
摘要翻译：顺序地检测输入音调信号的特定间距，并且基于特定间距依次检测对应于音调名称的标准化音高。确定检测到的音调是否存在变化。基于输入音调信号产生引导音（第一音调信号），并且基于检测到的音调产生和声（第二乐音信号）。当确定音调发生变化时，处理等待直到预定时间过去，并且如果在变化之前检测到的音调和当前检测到的音调被确定，则执行控制以改变第二音调信号的音高在预定时间过去时彼此不同。
