End from Piston Dreams by Agargara
PiSTON SOURCE is a netlabel that releases music made with Piston Collage (or PxTone for short), a chiptune/lo-tech music editing program for Windows. Its purpose is to show off the ways in which this little program can be abused. The music is "open source" in that anybody can open up the .ptcop files and see how the music was made.
