pxtone web is a fan site where you can share your pxtone pieces and listen to others. It has a web player that visualizes each of the voices in a piano roll or unit view.
pxtone collage is a free but powerful music editor made by Pixel, the creator of Cave Story and Kero Blaster. It stores music in its own compact ptcop format, but can export to wav. Go download it yourself and try it out!
Don't upload anything you don't own or it may be taken down. Please understand that the site does not prevent any .ptcop or .pttune you post from being downloaded by others.
Anyone can upload to this site, so even though they're music files, please take care before downloading and running.
Thanks to Pixel for making pxtone and releasing the source (and providing the full-size icon). Thanks to petamoriken for making the library that allows using the pxtone source from web apps. Thanks to all the pxtone composers for making awesome jams!
