Share your works and get some feedback in the output~ section. They can be audio, video, live performances, whatever. The only requirement is that they involve Pd. It doesn't have to be 100% Pd, there just has to be some.
This is not the place to share patches, however. This is for sharing recordings of some kind. Please post patches in the patches~ section.
Also, it's best to link to audio or video hosted on another site, such as SoundCloud or YouTube. You can't attach anything more than 1 mb on the forum, anyway.
