Abstract: A music and audio playback system is implemented on a computer with a playback engine that enables the operator to apply a variety of effects. The system may store one or more snapshots, or a combination of settings for a plurality of controls that are applied by the playback engine. These snapshots allow for changes to settings for effects, mixing and playback to be made quickly, some of which would normally be difficult to perform. A sampler module permits a user to specify one or more samples that may be triggered for playback. The most frequently used samples may be designated as scratching files that may be quickly activated through the push of a button (or other control). Additionally, a waveform display represents a window of audio samples around a current playback time.

Abstract: A music and audio playback system is implemented on a computer with a playback engine that enables the operator, typically a disk jockey, to apply a variety of effects. The system may store one or more snapshots, or a combination of settings for a plurality of controls that are applied by the playback engine. The settings that may be stored in a snapshot may be for effects, deck controls and/or mix settings. These snapshots allow for changes to settings for effects, mixing and playback to be made quickly, some of which would normally be difficult to perform. A sampler module permits a user to specify one or more samples that may be triggered for playback. The most frequently used samples may be designated as scratching files that may be quickly activated through the push of a button (or other control). A waveform display represents a window of audio samples around a current playback time. When two tracks are being played, only half of each waveform is shown.
