Abstract:
1. A tone synthesis apparatus comprising: a storage section that stores connecting waveform data for connecting between at least two notes to be generated in succession, the stored connecting waveform data including normal connecting waveform data and special connecting waveform data for reducing a delay in tone generation timing of a succeeding note as compared to the normal connecting waveform data, wherein one of the normal connecting waveform data and the special connecting waveform data is selectively read out from the storage section, said normal connecting waveform data containing waveforms of both preceding-note and succeeding-note regions of a waveform connecting portion that is provided for a continuous transition between the at least two notes, and wherein the special connecting waveform data containing only the waveform of the succeeding-note region; an acquisition section that acquires performance information in accordance with a progression of a select one of a real-time performance and playback performance; and a tone generation section that, when a connecting tone is to be generated for connecting between at least two successive notes in a legato style in accordance with the performance information acquired by said acquisition section, acquires the special connecting waveform data from the storage section if the performance information is based on the real-time performance, and acquires the normal connecting waveform data from the storage section if the performance information is based on the playback performance, said tone generation section generating a tone waveform connecting between waveforms of the at least two successive notes on the basis of the acquired connecting waveform data.
