Abstract:
1. A waveform generating system comprising a waveform generating apparatus and a computer, connectable with each other via a network, wherein the computer stores a tone generation program executable by the computer to function as an expansion tone generator, which can be accessed by the waveform generating apparatus, generating waveform data of a plurality of channels based on parameters set for each of the channels, and comprises a device for mutually communicating with the waveform generating device via the network, and wherein the waveform generating apparatus comprises: a tone generator generating waveform data of a plurality of channels based on parameters set for each of the channels; a memory that stores timbre data defining tone color of the waveform data to be generated by the tone generator; a communication device for communicating with the computer when the waveform generating device is connected to the computer via the network; a controller that obtains performance data, including a note-on data instructing to start a sound, in real time and, in response to the performance data, controls at least one of the tone generator and the expansion tone generator provided by the tone generation program executed by the computer to generate the waveform data according to the performance data; and a waveform outputting device that mixes the waveform data generated by the tone generator and the waveform data generated by the expansion tone generator provided by the tone generation program executed by the computer and transmitted by the computer to the communication device, and outputs the mixed waveform data, and in a state where the communication device is connected to the network, the controller operates based upon the connection state of the computer to the network, such that when the computer is initially connected to the network, when the computer is connected to the network and the connection paths have been set up on the network, when the computer is not connected to the network,
