In an audio signal processing device having a plurality of tracks recording an audio signal supplied from any of a plurality of buses, when a track is selected in accordance with an operation by a user, a bus supplying the audio signal to the track is searched, and when an appropriate bus is found and it is judged affirmative that a signal input device having an indicator whose display contents can be controlled by the audio signal processing device supplies the audio signal to the found bus, control data for making an indicator corresponding to a transmission port supplying the audio signal to the found bus perform a display indicating that the transmission port is connected to the selected track.

Audio signal processing system

In generating tone waveform data for each fixed or variable section via software of a personal computer or the like, a generation start condition is changed depending on an application of the waveform data. When the waveform data is to be sounded in real time, various programs are activated in synchronism with predetermined cycles, such as tempo clock and frame cycles, in order to generate the waveform data at accurate timing. When, on the other hand, the waveform data is to be recorded in a waveform file, various programs are activated on condition that waveform data generation processing has already been completed for a preceding section. Such arrangements can eliminate limitations to processing times of the programs and thereby provide a tone waveform of high accuracy.
