Giant Light Bulb Tone

Posted on April 2, 2009 by John C.S. Keston

I’ll have to do another session down at Grandpa-George sometime soon, because I have gotten a lot of mileage out the the sound possibilities in their space.

They didn’t know it, but their office is virtually a Foley studio. I doubt they’d let me lay down some sod, sand, and gravel to record footsteps though.

Douglas, Matthew, and Derrin all tend to collect interesting objects including a pair of giant light bulbs, probably for street lamps. This is the tone produced by flicking one of the bulbs.

Pencil Sharpening at Grandpa-George

This typical, mundane sound has become nostalgic in many respects, but not altogether antiquated. However, this example is less typical, mainly because the sharpener was not mounted on the wall.

Derrin and Doug had to work together; one person holding the sharpener down while the other one turned the crank. This gives the sound a laborious quality that’s interesting to me.

Spelunking with the GMS

Posted on March 31, 2009 by John C.S. Keston

A have completed a lot of functionality on my Gestural Music Sequencer recently. I added new keyboard controls to change the durations, create dotted notes, increase and decrease BPM, change to one of four preset scales (including a newly added whole tone scale), and toggle between “free mode” and “BPM mode”.

Free mode ignores the BPM and bases the intervals between notes on the mean brightness level of each frame. Since the brightness levels of video can vary dramatically from one environment to another I added a way to dynamically calibrate free mode. While the GMS is in free mode the up and down arrows calibrate the time intervals between notes, whereas, when in BPM mode the up and down arrows adjust the BPM.

Originally the note durations were set with the up and down arrows. Now it’s done with the bottom row of letters on a qwerty keyboard (z,x,c,v,b,n,m) with z being a whole note and m being a sixty-fourth note. All of these durations can be dotted or un-dotted by pressing the period key. This makes it easy to go from slow to very fast phrases instantly.

Here’s a two minute test recording I made to illustrate some of the new functionality. I used the new whole tone scale, and changed the durations with the new keyboard controls. I felt a bit like a cave explorer while making this recording. I had my Petzl headlamp on so I could gesture with my head as if I was looking down a dark cave, while manipulating the keyboard controls with both hands. I’d include a photo, but that’d be embarrassing.

GMS with New Timing Code

Posted on March 30, 2009 by John C.S. Keston

As I mentioned earlier I’ve added new timing code to the GMS. The feature allows you to dynamically change the duration of notes based on more precise timing. The durations range from whole notes down to sixty-fourth notes. I included dotted notes in the list, but I left out the tuplets for now. Currently changing the durations is achieved by the up and down arrows, but I’ll probably change it so that you can go from a one duration to another without having to scroll through them all. I also setup a “free” mode where the timing ignores the BPM and bases the time intervals between notes on the average brightness of the frame. I’ll write more about that later. For now here’s a test recording using the new timing code at 120 BPM.
