GMS Audio Captured During MAW Outing

This eight minute segment of audio generated by the GMS is from the first eight minutes of our most recent MAW (minneapolisartonwheels.org) outing.

This was my first chance to take advantage of the presets feature, but the performance led me to expand the octave setting to include adjustments for the top and bottom octaves. During this performance the octave setting was limited to only allowing the top octave to be lowered. This made it so that instruments with a limited range, like drums, are difficult to play since much of the screen might be inactive.

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.
