GMS Video Experiment w/ Reason from Dane Messall on Vimeo.
My student, Dane Messall, has been experimenting with the GMS over the break and just posted this video experiment. He imported the video into the GMS and then interfaced it with Reason’s Thor synthesizer to generate the sound. Nice one, Dane!
As the GMS approaches three-hundred downloads, I’m starting to get a few questions regarding technical problems. It’s exciting that people are starting to use my software, but as an individual developer, who is also a composer, instructor, performer, and student, I don’t have time to diagnose and troubleshoot every problem on every system.
Therefore, I am asking for your help. If you have downloaded the GMS, please post a comment here describing your success stories or problems. In either instance, please include details about your environment including the operating system, computer specs, camera in use, and if you’re using internal or external sync.
I’ll do my best to respond to Mac issues, but I don’t have consistent access to Windows. If you’re up and running on Windows please respond to questions if you have ideas on how to fix the problem. As always, I’m interested in hearing what you do with the GMS, so post a link to your tracks, and thanks to everyone for participating.
GMS v0.10 beta binary distribution for Windows is now available, thanks to Grant Muller, who compiled the latest source code for the GMS under Windows. Please visit the GMS page to download the Windows version. If you’re interested in the source code for the GMS you can find it at http://code.google.com/p/gestural-music-sequencer/.
This Wednesday, December 9, 2009, 7pm – 10pm I’ll be performing music at the West Bank Social Center. The space can be found above the Nomad Bar, 501 Cedar Avenue South, Minneapolis, Minnesota, and is accessible by an exterior door on the north side of the building. These events are entertaining mash-ups of creative ideas from a variety of artists producing interactive projection pieces. Checkout the video documentation from the last event where I played. I’ll probably be using a combination of vintage Hammond organ through laptop, gestural generative sequencing, and custom grain table madness, all arranged in real-time in Ableton Live.
The GMS source code is now available on code.google.com. I’ve still got loads of idea for improvements and feature additions, but I’m also interested to see what input other developers might have for the project. Therefore, the code is now officially released and available as Open Source under the GPLv3.
Please let us know how you are using the GMS. I’ve been informed that Grant Muller will be using it experimentally on a jazz improvisation project he’s involved in. Rocky Rosga is producing some work with the GMS. Finally, my duet project with Graham O’Brien on drums has recorded an album (it will be a few months work to edit and mix, so don’t look for it anytime soon) of GMS improvisations with live drums.
I have decided on September 28, 2009 as the release date of the GMS, coinciding with my performance with Graham O’Brien, and my birthday. We can call it a combination Ostraka with Dial System and DJ Zenrock show, GMS beta software release, and birthday party. Currently I am releasing a binary version of the software for Mac OS X only. A windows version is in the works, with no prediction of when it’ll arrive.
The GMS is a Gestural Music Sequencer that I developed in Processing (processing.org). The application samples video and displays it either normally or inverted so it looks as though you’re looking into a mirror. Each frame is analyzed for brightness, then the X and Y data of the brightest pixel is converted into a MIDI note. These notes produce a non-repeating sequence based on movement within the range of the capture device.
For more details, including audio examples and video produced using the GMS, checkout the
GMS category. There’s also a Gestural Music Sequencer Documentary Short produced by Josh Clos, that does a good job of illustrating what the software does.
I have decided to release beta version binaries of the GMS for both Mac and Windows sometime next month. There a few bugs I have yet to solve, like the application freezing if you choose the video device more than once. I’ll be including a readme that lists the known issues along with the application files.
One of the reasons for doing this is to get some feedback on the tool, and find out if anyone is interested in continuing development on the project as Open Source. There are some pretty tricky issues with Processing and video that perhaps a more advanced developer than me might be able to optimize easily enough. I am interested in moving on to some other projects, and am fairly satisfied with how the GMS works for my own purposes at the moment.
If anyone is interested in experimenting with this tool (I know of a few interested parties so far), let me know in a comment and I’ll gauge my efforts on getting a beta out soon or over a more extended time period based on your feedback.
If you have been wondering why ACB is a little bit on the slow side lately, it’s because I have been quite busy doing other things, like my night class at CNMAT and releasing my solo album, Precambrian Resonance. So, after presenting 365 sounds in 365 days, I’ve been having a bit of a rest.
But now I am ready to dive into some new projects, including my duet with Graham O’Brien (drums) that we’re calling Ostraka with Dial System. We recently performed at a club in Minneapolis, but I neglected to record the show. However, I saved my document with the GMS clips I had captured. Here’s a short mix of a few of the remnants from the performance, unfortunately lacking the drums.
It was recently estimated by Edward Guinan at the XXVIIth General Assembly of the International Astronomical Union that our lonely planet is nearing the end of its habitability for life as we know. Albeit, on a cosmological timescale. Between .5 and 1 billion years from now, increases in the Sun’s temperature will cause the Earth’s oceans and atmosphere to evaporate.
Shortly after reading this article I opened up my Ableton Live set from Sunday night to listen to some of the loops I had captured with the GMS during the show. After opening the document I pressed play and heard a stark landscape of reverberation. I saw visions of a lifeless, peace 500 million years from now.
What had happened was that when saving the document I had left all my master effects in their last position. I decided to capture these sounds and vary them over time. The effect chain on the master track included a low pass filter, bit reduction, delay, and reverb with nine parameters mapped to knobs on a controller. Here’s what I ended up with on the second take.
I have had a number of problems migrating my Processing.org application known as the GMS from my old MacBook Pro running OS X 10.4.11 to my new one running 10.5.7. The first issue was alack of support for the IAC drivers in Java, next were some funky conflicts with the Java class I was using to load and save presets. With the help of Grant Muller I have solved these problems.
While I was at it I took on a couple of other issues as well in preparation for my performance on Sunday. All that’s left is for me to become reacquainted with the application in tandem with Ableton Suite 8.
This is actually the hard part because I have use the application effectively as an instrument and real-time visualizer. One problem is running out of hands and fingers while producing the visuals and capturing the MIDI clips. Another danger is the music becoming repetitive while making adjustments. Here’s a quick recording I made while practicing.
