POCO, a workbench for research on expression in music

Musical performance data often requires a lot of preprocessing, matching, filtering and tabulation before ,e.g., statistical analyses can be made. Complex processing is needed as well for the generation of musical stimuli and the manipulation of musical data. Tools for these operations are made available in a neat modular form all based on a shared representation of musical data in textual and MIDI file formats. A preliminary version of this system is already available for researchers and is used worldwide. Various parts of POCO will be developed further.
