comp-i: A System for Visual Exploration and Editing of MIDI Datasets

Conventional sequence software systems, which are commonly used to edit MIDI-encoded music, possess two kinds of problems due to interactions with MIDI data through multiple independent windows. We address the problems by developing a system, called comp-i (Comprehensible MIDI Player Interactive), which provides music composers and arrangers with a novel type of 3D interactive virtual space, where the users are allowed to explore global music structures and to edit local features, both are embedded in a time-series of multichannel asynchronous events of MIDI datasets while keeping their cognitive maps.
