Abstract: A computer-implemented method includes receiving input data including MIDI events arranged in a timeline, determining a target grid position from among the plurality of grid positions, determining a search range around the target grid position, and identifying a set of MIDI events within the search range around the target grid position. The method further includes determining a reference point for the set of MIDI events based on a function of the set of MIDI events, adjusting a position of the reference point toward the target grid position, determining a proportional movement for each MIDI event on the timeline based on its location relative to the adjusted reference point, and adjusting each MIDI event based on the determined proportional movement. The function of the set of MIDI events can be a weighted average based on one or more MIDI characteristics of the set of MIDI events.

Abstract: A computer implemented method allows a user to adjust tracks in a musical arrangement. The method involves a user selecting a musical position of an audio track, which the user desires to adjust in time, either by compressing it or expanding it, by indicating with a pointing device, such as a mouse, the position in the time line of the audio track that the user wishes to alter. A first marker is then displayed at the selected musical position in the audio track. Boundary markers defining transients in the audio signal surrounding the selected musical position are then automatically generated by analysis of the audio signal, and are displayed on the audio track. The two boundary markers define an audio segment that is to be adjusted in tempo by the user moving the first marker along the time line.
