On Wednesday, November 16, 2011, Olivia Solon of Wired.co.uk wrote an article describing my piece, Voice Lessons. I have creativeapplications.net to thank for this one. Olivia found the article about my piece there and then emailed me to ask for a brief interview. We conducted the interview over email and the article was published the next day. Read the article by Filip Visnjic on Creative Applications Network. Read the article from Olivia Solon on Wired. Thanks, Filip and Olivia!

Voice Lessons is an electronic, audio device that interrogates the popular myth that every musical instrument imitates the human voice. Touching the screen allows the participant to manipulate the visuals and vocalizations of the “voice teacher” as he recites vocal warm up exercises.

The piece resides in the space between a musical instrument and voice lesson. Move the touch point left, right, up, and down to explore the visual and auditory possibilities. Rapid high pitched loops occur while touching near the top of the screen while lower pitched longer loops are heard near the bottom.

The actor, also named John Keston, is my retired father who became a voice teacher after a long career on stage in plays, operas, and musicals with the Royal Shakespeare Company in our native country England and abroad.

Voice Lessons
32” interactive touch screen installation
By John Keston 2011

This video documentation was shot while Voice Lessons was installed at the MCAD Whittier Studios for a session of the graduate critique seminar in November, 2011.

The piece, developed in Max/MSP, granulates both sound and video in parallel as the viewer touches the screen. Synchronization between the the audio and visual content is maintained. The piece will be installed again for an open studio night on December 9, 2011 (6 to 10pm) at the MCAD Whittier Studios, 2835 Harriet Avenue South, Minneapolis.

The image above shows the main patch window for Voice Lessons. The X and Y coordinates of the touch-screen are translated into position, frequency, and grain width for the audio and video. When the screen is not being touched video without sound of the subject looking around the environment is played. I call this the idle mode and it serves to attract the viewer into interacting with the piece.

When the idle mode has been active for 1.5 seconds a new video and corresponding sound is randomly selected from a pool of five possibilities. Each video is a distinct performance of vocal exercises that explore a variety of vowels and consonants.

Voice Lessons is an interactive touch-screen installation that I recently presented during a graduate critique seminar at MCAD. The piece, developed in Max/MSP, granulates both sound and video as the viewer touches the screen while maintaining synchronization. I will be installing the piece again next month for an open studio night on December 9, 2011 at the MCAD Whittier Studios, 2835 Harriet Avenue South, Minneapolis. I will also be sharing more complete documentation about the piece soon. For now, please enjoy this short segment of audio sampled from the piece as it was in use.

Voice Lessons Excerpt

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.

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!

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.

Grain Machine Experiment

I’m working on a MaxMSP performance patch that uses a Wacom tablet to draw light onto dancers holding light sensitive instruments. Last night we decided to apply sound to the strokes to give the illustrator another way to interact in the piece. Currently the pressure from the pen is translated into the volume and the velocity is translated into pitch. It will need some fine tuning, but I think you can get the idea from the video.

I have converted a Max patch I build into a Max for Live device as an exercise for learning M4L. The original patch is a monophonic step sequencer that I wrote about in Step Sequencer Built in MaxMSP. I ran into some difficulties converting the patch along the way. Although it worked perfectly in Live, for some reason it was causing Live to crash after saving. It was also not storing the values in the Live number boxes, drop-downs, and sliders. The problem went away when I went through the tedious process of recreating the patch rather than copying and pasting my original work. This is a little worrisome since the next conversion will not be so simple (Multitouch Rotary Dial and X-Y Granular Exploration). Here’s an audio example with a little reverb to give you an idea of what it does.

It’s also about time I mentioned that I’m in the process of producing a new Ostraka album that features Graham O’Brien on drums. We recorded it recently at Masters Recording, formerly Flyte Tyme of Jimmy Jam and Terry Lewis fame. The studio was just sold again and from what I understand will be called Madison Media Institute. In any case it was an amazing facility to lay down tracks. Here’s a shot of our setup in Studio A.
