In Out Festival Track Donation: Entropy Procedure by Ostracon

Posted on September 14, 2010 by John C.S. Keston

I’m pleased to share with ACB readers the track donation that we made for the In / Out Festival Kickstarter project. The track is titled Entropy Procedure by Ostracon and features myself on the GMS interfaced with Ableton Live, and Graham O’Brien on drums. It was delightfully engineered and mixed by Adam Krinsky, and mastered by the amazing Tom Garneau who, if you read his discography you will find, recorded and mixed Too Legit to Quit by MC Hammer (an unrelated but awesome bit of data for you).

We will be performing similar work to this at the In / Out Festival this weekend on Saturday, September 18, 2010 at 9:30pm at the Tank Theater in Manhattan. Please checkout the entire festival starting on Friday afternoon with free workshops and finishing with the Saturday evening performances. The evening performances are only $15 per night, or $25 for both nights with a total of nine performances. This is unlike any music I have produced in the past, so comments are encouraged.

Control the GMS Via Ableton Live

Posted on September 7, 2010 by John C.S. Keston

Currently I am busy preparing for the Ostracon show at the In / Out Festival of Digital Performance that is coming up on September 17 and 18 in New York (we are playing on the Saturday the 18th at 9:30pm). Part of my preparation involves minimizing my setup for ease of transport. For one thing, I am not bringing my Korg MS2000 as a controller for the GMS, as I have done for other performances. However, because I’m projecting the live video source, I cannot use the on-screen controls in the GMS.

My first idea to solve this problem was to share a single Korg nanoKONTROL between Ableton Live and the GMS. Unfortunately this approach was not practical because it would require some major reconfigurations as well as recompiling the GMS with a set of new external MIDI controls. My next idea was to route the MIDI control and program changes to the GMS via MIDI clips in Ableton’s session view. This worked immediately and I knew I was on the right track. The only problem was that there seemed to be a MIDI signal feedback loop when using the same bus for output and external control in the GMS. I solved this problem by creating a second IAC bus for the external control and using the first bus for the MIDI output. Finally I configured a combination of keyboard controls and Korg Nano buttons to trigger the clips in Ableton that, in turn, trigger the specific functions in the GMS. Voilà!

The flexibility of Ableton never ceases to amaze me. I had never used session clips to send MIDI program and control change messages to an external device, let alone, independent software running simultaneously. Nor had I ever needed to do this in the past. Yet the thought occurred to me, I wonder if Ableton can do this? It turns out that it can. Thanks to Ableton this solution has saved me many hours of redundant and tedious programming, and well as making my setup more streamlined and efficient for upcoming performances. How have Ableton’s capabilities surprised you?

Grain Machine Update and Layered Experiment

Posted on August 2, 2010 by John C.S. Keston

Here’s a new look at the Grain Machine M4L device. Since last time I have updated the device to allow drag and drop samples that are stored with the Live set, and added a visual for the filter that’s controlled by the accelerometer on the controller (iPad, iPhone, or iPod Touch).

The best thing about using this in Live is being able to live-loop and layer the output from Grain Machine into clips on different tracks, not to mention processing. Another advantage is saving the state of the device in the Live set so that one document has sample set X, while the next has sample set Y. Here’s a piece I created with the Grain Machine in Ableton Live using some samples I randomly selected from my sound library.

Monophonic Step Sequencer Max for Live Device Download

Posted on July 31, 2010 by John C.S. Keston

I have had a few requests to share this device so here’s a download link. Please enjoy it, and if you make some interesting music with it, please post a link in the comments. Also, if you’re a M4L developer and make some improvements or enhancements to the device we’d love to see what you do. Thanks!

Grain Machine Max for Live Instrument

Posted on July 30, 2010 by John C.S. Keston

The Grain Machine v0.1

Something I have been meaning to do for a while was convert the MaxMSP instrument that I titled the Wavetable Glitch Machine (WTGM) into a Max for Live patch. The WTGM uses a TouchOSC interface running on an iPhone, iPod Touch, or iPad to explore samples using granular techniques as well as a virtual scrub dial with friction modeling. Visit the WTGM tag to read more and view a video of it in operation. I have renamed the instrument Grain Machine for the M4L version.

First I prepared the patch for transfer to M4L. This involved making sure that all of the interface objects were in the main patching window, reorganizing the sub-patchers, and cleaning up a variety of other things that I imagined might interfere with the process. Following that, all that was left was copying and pasting the patch into a Max Instrument, replacing some of the standard Max objects with M4L objects, and building a tidy little presentation mode.

Although I had to rework some of the logic and patch cords, the conversion went surprisingly fast. I expected to be working on this for weeks, but it only took me a matter of hours to get it into working order. There is still some fine tuning to be done, but all the necessary functionality is in place. Here’s an audio example I made with a simple breakbeat loaded into the Grain Machine.
