I will be posting here some example Quartz Composer files that take advantage of the hooks between Serato and QC.

Here is the first one:

mansteri.com

Check out the video and download the .qtz. Some general information and a Visual Scratch (jklabs.net) type of example.

I haven't found much official documentation about the QC stuff, but I gathered everything I know about it on that post.

I would also love to see what other people do with QC and Video-SL.
