PxTone Collage is a freeware music editing program. The program is in development by Daisuke "Pixel" Amaya. It is currently in the beta stage of development. The format is similar to MIDI files in many ways. A prominent difference includes instrument samples ("voices") that are stored within the song data itself. PLEASE NOTE: For English users, simply delete the japanese.ico in the download folder. The program also is capable of opening other sample formats developed by Pixel (ptnoise, ptvoice) as well as some more popular sample formats, such as .wav and .ogg.[1] The primary interface of the program is a piano roll display used to place notes and specify duration, volume, panning, sample, and pitch. The tempo of a song can be set, but it cannot be changed during playback. The .pxtone format also allows the storage of some additional information, such as song comments and song name. Along with Pxtone Collage are included several programs for creating instrument samples (ptnoise and ptvoice format) and a small player application. Included also are DLL and header files for programming with PxTone.
