摘要： In response to detection of a note-on instruction, a CPU assigns a tone generating unit comprising two tone generating channels and sets tone color control data of the assigned tone generating unit into tone generator registers. The tone color control data includes a parameter common to the two channels. Once the CPU gives a tone generation start instruction to a tone generator, the tone generator accumulates a frequency number common to the two channels to thereby generate a progressive phase common to the two channels. Waveform readout section reads out left-channel and right-channel waveform data from a waveform memory on the basis of the phase and waveform selecting information of the left and right channels. Tone characteristics of the read-out left- and right-channel waveform data are controlled by a characteristic control section on the basis of a characteristic control parameter common to the two channels.

摘要： A CPU 19a supplies parameters on musical tone signals to a tone generator 17 having a plurality of tone generation channels CH0, CH1, . . . , CH127 each generating a musical tone signal. The parameters include channel information which designates one or more of the tone generation channels, and musical tone information which defines respective musical tone signals which are to be generated in the respective tone generation channels designated by the channel information. The tone generator 17 has a tone generation reservation circuit 17b which makes the designated tone generation channels start generation of the musical tone signals defined by the musical tone information when the respective tone volume levels of musical tone signals currently generated in the tone generation channels designated by the channel information are equal to or below a certain tone volume level.

摘要： First display object associated with a control operating member and a second display object associated with a tone color effect parameter are displayed, and variation of a displayed position of the first display object is controlled in accordance with operation of the control operating member. Control value of the tone color effect parameter is determined in response to variation in relationship between the first and second display objects, and tone control is performed on the basis of the determined control value. Further, the variation of the displayed position of the first display object is controlled so as to move on and along a set path, so that displayable positions of the first display object is limited to the set path. Control value of the tone color effect parameter is determined on the basis of relationship between displayed position of the first and second display objects to perform tone control.
