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.
