An envelope shape generator generates envelope shape data for controlling a tone signal in the form of data in decibel representation. In performing a rapid attenuation control called "forcing damp" during attenuation of the envelope shape data generated by the envelope shape generator, the envelope shape data in decibel representation is rapidly attenuated with such a characteristic that inclination of attenuation becomes increasingly steeper. This is advantageous because inclination of a rapidly attenuating portion is modified to a substantially uniform inclination when the envelope shape data is converted to data in linear representation. There are also provided a detection circuit for detecting that the level of the envelope shape has dropped below a predetermined level corresponding to a minimum level at which a tone waveshape can be effectively represented and a circuit for rapidly attenuating the envelope shape in response to this detection. This contributes to elimination of noise.

A multiple access communication system performs the communication between plural communicating units using plural communicating channels and a common signalling channel for establishing and releasing the communicating channels. The communication system comprises the steps of allocating at least one carrier frequency to the common signalling channel; allocating the carrier frequencies, which are different from the carrier frequency alloted to the common signalling channel, to the communicating channels; forming a time frame composed of first and second time slots by the common signalling channel and communicating channel, respectively; and allocating the first time slot to at least the common signalling channel and the second time slot to the communicating channel.A multiple access communication system performs the communication between plural communicating units by selectively allocating plural carrier frequencies, which are different from the common signalling channel carrier frequency, to the plural communicating channels, and using a common signalling channel for establishing and releasing the communicating channels. The commnication system comprises the steps of constituting a time frame of communicating channel by at least one packet; selecting transmission parameters of the communicating channel including at least transmission speed, packet length and packet position from plural transmission parameters prepared in advance; and setting the selected transmission parameters through the common signalling channel.

A tone generation circuit can generate digital tone signals in a plurality of channels on a time shared basis and these digital tone signals are supplied to a digital-to-analog converter provided commonly for the respective channels. The digital-to-analog converter converts the digital tone signals of the respective channels into analog signals individually for each of the channels in the time division multiplexed state. Analog memory circuits are provided for the respective channels for demultiplexing and individually holding the time division multiplexed analog tone signals supplied from the digital-to-analog converter. The analog tone signals held in the respective analog memory circuits are individually read out in synchronism with pitches of notes assigned to the respective channels. An analog adder is provided, when required, for summing up the read out analog tone signals of the respective channels.
