PxTone Collage (Japanese: ピストンコラージュ, Hepburn: Pisutonkorāju) is a freeware music editing program.

It is used to place notes and specify duration, volume, panning, and pitch, among other things.

Along with PxTone Collage are included several programs for creating instrument samples (.ptnoise and .ptvoice format) and a small player application.

Some time later, Pixel developed the Organya (OrgMaker) format for use in the indie game Cave Story.

[3] Rather than having the specifications of the waveform editable, Organya uses a built-in library of 100 wave "instruments" to choose from.
