A waveform data processing apparatus includes a waveform data recording device which records waveform data representing waveform samples, and a waveform events track recording device which records, on a waveform events track defining a musical progression with respect to time, waveform event data representing events for employing waveform samples to constitute a musical performance as the alignment of the waveform samples. The waveform event data contains trigger signals at time points where retpectively corresponding ones of the waveform samples are to be employed along the musical progression on the waveform events track. As the waveform events track is played back, the respective trigger signals serve to trigger the playback of the corresponding waveform samples to constitute a musical performance with such waveform samples. Each of the waveform samples represented by the waveform data defines a musical tone having a build-up point. The waveform data may be split at a build-up point to form waveform sub-samples, while the waveform event data will further contain trigger signals corresponding to the split sub-samples. Other than splitting, further editions are available such as deletion, insertion, copying and pasting of a part or parts of the waveform data.
