GMS Piece: Dodger of Red Lights

Today I decided to see if I could create a version of what I performed at the MAW outing last night, as a streaming video with good quality sound. I opted not to use screen capture software so that all the processing on my Macbook Pro could go into rendering the images and sound. The imagery was created by manipulating a red, LED, bike light near the lens of the camera. The screen was then shot with a second camera while the audio was recorded externally using my PCM-D50.

I built a pentatonic scale using the note probability distribution feature in the GMS. The most likely note was a C followed by D, G, G#, and then B natural. I also used the probability distributions on the durations to get some stumbling rhythms centered around sixteenth notes.

Thursday was my first outing with Minneapolis Art on Wheels (MAW) and my first opportunity to project my work on the GMS in a public space. The sheer scope of the event was impressive. My friend Kevin could hardly believe all of the equipment that was transported by bicycles to the location. There was some really good work on display, some bizarre random events, and exhaustive video documentation that I expect we’ll see on MAW soon.

After the outing, on the ride back to base, everyone was giddy from the nice weather. We get a bit cooped up during the long Minnesota Winters. In not one of my finest cases of judgment I decided to dig out my PCM-D50 from its protective case and record the proceedings while riding my bike. I don’t necessarily recommend this sort of behavior, but I held on tight and threw caution to the wind. Here’s a segment of audio from the bike ride back.

GMS Probability Distributions

The most recent addition I have made to the GMS is probability distributions for note pitches and durations. The way this works is that the user adjusts sliders from zero to one-hundred for each note in the twelve tone (chromatic) scale.

When note probability distributions are enabled, the randomness is weighted so that notes set to zero will never play while at one-hundred the note has the maximum probability of playing. This way the user can setup any sequence of notes in a scale or chord, then toss in a small (or large) possibility for an altered or dissonant note.

The same is true for duration probabilities except that I have the dotted durations as a separate possibility that is applied to the duration determined by the weighted random function. Here’s an example of the note and duration probability distributions in action with the settings as shown in the image.

ACB contributor, recording artist, educator, one-man-software-house, installation artist, and luthier, Leafcutter John is having a remix competition. Click the image for more details on how to enter the competition. I’d love to be involved, but am too busy with my GMS and other projects at the moment. Hopefully some ACB readers will take this on so I can live vicariously through them. There’s lots of really good remixes already, so get cracking!

Freesound.org Loop

One thing I often do when illustrating to my students the breadth of sounds available on Freesound.org is to start looping multiple sounds simultaneously to instantly create a new sound piece. I never really bother capturing these, but recently I routed the output to Pro Tools as the loops were going in Freesound and got this result. The sounds used can be found here.
