I think this new ongoing Overlap Salon that we are putting on through Overlap.org is going to be nice and fun. If you are into cutting edge music, audio performance, and the technologies related with these, I urge you to come out to this new regular event. Christopher posted more on Overlap.org about this:

This first Overlap Salon event brings together users of Cycling 74′s legendary “build-it-yourself” software universe Max/MSP/Jitter. Cool Max/MSP/Jitter nerds will be able to meet, exchange knowledge, advice, and software patches. Max/MSP/Jitter patches covered in the Salon will also be shared on Overlap.org following the event. All participants are required to bring your their own laptop, beer (if u want) and thinking cap. WIFI provided.

I will bring beer. I wonder if we have any more free beer at Creative Commons actually Anyone interested in coming to this and/or presenting? Let us/me know! If I talk about anything, it will be the anti-max/msp/jitter called PD which I used to hack on back in the UCSD-aze. Also, if you show up, maybe I will talk more about why Lil Wayne is so brilliant and use my Eeepc as an awesome DJ’ing platform.

I’ve been thinking about slitscan effects ever since the Biosphere and Egbert Mittelstädt performance at Recombinant Media Labs last year. Egbert uses slitscan techniques to great affect, and the surround cinema format of RML was a perfect canvas for his work.

The rendering process he uses took quite some time, a majority of the week leading up to the show, and so I wanted to explore the possibilities of realtime effects using hardware acceleration and the GPU. For a fairly comprehensive catalog of artists using slit-scanning techniques, see Golan Levin’s compilation.

For my implementation I used Max/MSP - Jitter. Its GPU processing and shader tools made it fairly easy to come up with a fast slit-scanner at high resolutions. The Jitter Slitscan Source contains both a CPU and GPU version of this patch, to attempt to accommodate many hardware configurations. To run this code requires the Max/MSP and Jitter runtime, or the full version if you want to edit the code.

The scan at the top of this post is sourced from a performance of Crosstalk by Jay Cloidt and Nancy Karp + Dancers. The following image is sourced from a soundcheck by Triometrik.
