Abstract
A detector unit is provided which receives envelope signals related to a predetermined number N of channels to detect a channel showing a greatest or smallest level of the envelope signal among the N channels and outputs data indicative of the detected channel and the level of its envelope signal. When the total number M of the channels is larger than N, a plurality of the detector units are provided, the envelope signals of the number M of the channels are divided into groups numbering not more than N, and the groups are distributed to the respective detector units so that the channel of which level of the envelope signal is the greatest or smallest is detected in each of the detector units. The levels of the envelope signals of the channels detected by the respective detector units are compared with each other, and one detector unit connected with the channel of the greatest or smallest level of the envelope signal is identified. Thus, the channel detected by the identified one detector unit is designated as an extreme-value channel. The designated extreme-value channel is for example a truncating channel to be used for tone generation assignment process.
