Abstract: A method to process digital audio data displays the digital audio data in one or more tracks along a time line in a graphical interface of a computer system and defines arrange regions within the time line of the digital audio data as objects for manipulation. Tracks within a selected arrange region are processed as an entity in accordance with commands received through the graphical user interface.

Abstract: The invention relates to systems, methods, and apparatus for assessing a musical performance. The musical performance can include a user's performance of a musical instrument. MIDI or audio notes are input and compared to the notes of a music track. An indication is provided to assess the musical performance. The assessment can be on the basis of timing and/or pitch errors.

Abstract: A digital audio processor is described, wherein a graphical user interface is presented on the monitor of the processor to display user actionable control elements in a scene of a real world environment for creating and processing music; the graphical user interface is adapted to activate pre-set functions for generating and processing digital audio data in the digital audio processor for each of the user actionable control elements.

Abstract: A graphical view of a file component associated with an audio that is displayed in a graphical user interface (GUI) is automatically switched during playback of the audio. The switching is based on a Musical Instrument Digital Interface (MIDI) view-switching track associated with a project file for the audio. In various embodiments, a musical instrument displayed in the GUI is automatically switched during playback of the audio based on a MIDI instrument-switching track associated with the same project file. Additionally, a metronome beat associated with the audio is automatically switched between on and off during playback of the audio based at least in part on a MIDI metronome-switching track associated with the song audio.

Abstract: A song audio is played and a graphical representation of a musical instrument contributing to the audio is displayed. A fingering display is overlayed on the graphical representation of the instrument during the playing of song. The fingering display is synchronized to the song audio. During the playing of the song audio, the tempo of the song is adjusted. The pitch of the song is substantially preserved in real-time despite the tempo adjustment. In addition, the synchronization between the fingering display and the audio are maintained in real-time in view of the adjusted tempo.
