Hello, I am the manager of Piston Source, a now mostly-dead netlabel dedicated to sharing cool/weird music made with pxtone.
The idea was to encourage sharing .ptcop files in order to learn, remix, and borrow samples. Thus every release comes with the original source files!
We haven't released anything in years, but there are some pretty good deep cuts. Check it out! http://pistonsource.agargara.com
