Abstract
An electronic musical instrument is provided with a touch data generating device and a reverberation unit which generates a reverberation signal. The reverberation unit generates the signal correspond to the musical tone signal based on the touch data. The reverberation unit has a reverberation parameter forming device for forming a reverberation parameter which controls the reverberation signal based on the touch data. The parameter includes a delay period for a delay element and/or a coefficient for a multiplier. The musical instrument is allowed to add a mixing device to it, for mixing the musical tone signal and the reverberation signal. The musical instrument is also allowed to have a channel detecting device for detecting the number of instructed channels in place of the touch data generating device, thereby the reverberation signal being controlled by the number of the instructed channels.
