In this installment, we'll be working on some more advanced ninja tricks - creating the beginnings of a control/preset structure with assignable LFOs, and building a GPU-based video delay effect. These two parts will bring our system to a much more usable level, and allow for much more complex and interesting results. Ironically, most of what we are really doing in this installment is just an extension of bread-and-butter Max message passing stuff.
Keith McMillen Instruments recently impressed all of us at NAMM with demonstrations of a new pair of string performance devices, the K-Bow and StringPort, both of which include some very rich software applications written in MaxMSP. The K-Bow, a bluetooth-based wireless gestural controller integrated into a violin bow, has just started shipping so we thought it would be a good time to catch up with Keith and find out more about the project. I met Keith at his studio...
In our last article, we began to create our processing system by putting the essential structure in place and adding our input handling stage. In this installment we are going to be adding a gaussian blur and color tweaking controls to our patch.
In this, the final episode of our guitar processing extravaganza, we are going to step away from making effects and focus on performance support. For a system as complicated as this, performance support means two things: patch storage and realtime control. Thus, we will learn to create a preset system and manipulate the various on-screen controls with an inexpensive MIDI footpedal system.
At this point, we have a pretty useful guitar processing "rack", but it could use a little spice. This spice will come from two additional processors: a looping delay unit, and a basic reverb system. Also, to help keep the output useful, we will drop a limiter on the back end of the entire rig.
This article provides a brief tour of the features we've added to Max for creating Live devices.
Between the tutorials, Jitter Recipes, and all of the example content, there are many Jitter patches floating around that each do one thing pretty well, but very few of them give a sense of how to scale up into a more complex system. Inspired by a recent patching project and Darwin Grosse's guitar processing articles, this series of tutorials will present a Jitter-based live video processing system using simple reusable modules, a consistent control interface, and optimized GPU-based processes wherever possible. The purpose of these articles is to provide an over-the-shoulder view of my creative process in building more complex Jitter patches for video processing.
When you think of multimedia technology you think mostly about the technology. When you experience Dana Karwas' work you think of the rich organic layers of experience. Dana is working in the nebulous grey area between art and design. As a trained architect she is commissioned to do design works for giants such as Knoll, yet as an artist she creates amazingly tactile and organic performances like her work Party Dress and the installation Fursicle. Although based in architecture, Dana’s work uses high-end technology such as Max/MSP to explore social interaction and levels of identity within public space.
In the last article, we added some basic tonal effects: distortion/overdrive and EQ/filtering. This time, we will expand our virtual effects rack to include both a phase shifter and a full-featured modulating digital delay. As we add these effects, you will begin to see why a DIY effects system can trump any commercial product.
This week the new Eowave OEM USB boards arrived at Cycling '74 HQ, and I was all too happy to give it a test drive. After having read the impressive spec sheets I was eager to see if the performance of the board lived up to all the promise. I quickly set to work putting it through its paces.
These days it seems that everyone wants to be an artist so I found it refreshing to meet someone who see himself as an engineer that wanted to create tools for artists. Mattijs Kneppers spoke to me by phone from his home in Holland.
Now that I've got a nice generative patch and a way to hear it, I thought it'd be nice to make a few improvements and extensions that would let me begin to specify larger structures - to generate instructions to my generative patch, as it were. While I'm sure that the world is full of people who want ways to have the same thing happen again and again, I'd like to do this in ways that offer a little more freedom than that. This short tutorial will add a modest number of these kinds of changes.

In the last article, we did a lot of setup - we got input/output handling in place, and added a compressor to the processing chain as an example of an “effect module”. In this article, we will continue adding effects, including a dual overdrive module and a three-stage EQ/Filter module. With these additions we will further explore Max 5’s user interface options, as well as taking a look at some of the “tweaks” that make Max/MSP functions a little more guitar-faithful.
Last week, Siggraph 2008 took over the Los Angeles Convention Center, and Cycling '74 was there to bravely represent Jitter to a huge crowd of CG enthusiasts, production professionals, and academics. For anyone who hasn't been to a Siggraph show, it is a huge, over-stimulating event for the computer graphics community, complete with academic talks, screenings, an exhibition hall, an art show, competitions, and a job fair.
Recently, CNMAT at UC Berkeley held their annual MaxMSP/Jitter summer school classes at their beautiful Arch St. facility just off the UC campus. This year, for the second year in a row, I had the pleasure of teaching the Jitter Night School - a 3-night intensive of focussed tutorials covering a variety of Jitter topics.
