Tone Matrix Composition

I recently stumbled upon a Flash instrument called Tone Matrix created by Andre Michelle. This is a slick little sine wave synthesizer triggered by a simple sixteen step sequencer. After goofing around with it for a half hour I decided to record some of what I was doing. So, here is a little ditty called “Faded Diary” inspired by Tone Matrix. The main morphing pattern in this composition is the piece that I recorded from my Tone Matrix session. The rest is an assemblage of synth, fretless bass guitar, and lots of little programmed bits. Check out Audio Tool too. Fun Stuff!

Chromatic Currents Part I

Here’s a segment of sound from another GMS video I produced yesterday called Chromatic Currents. Once again I was letting the visuals drive the piece, while I controlled parameters in the GMS. On Sound Globules I used the circle of fourths with probability distributions so that C was the most frequent note followed by F, Bb, Eb and so on. I really liked the rare dissonant pitch making its way into the sequence, so I tried a similar technique for Chromatic Currents. The scale was strongly C minor pentatonic, weighted with the Dorian mode by adding less-likely probabilities for D and A. However, every note that was not part of the scale still had a small possibility of occurring. This led to occasional blue or dissonant pitches in the stream of notes. The possibility of having any note within a chromatic scale occur in the stream led me to the title.

GMS Videos and Interface

Today I made two more videos with the GMS using a different technique than in Dodger of Red Lights. This time I wanted to explore what could be produced using visual input that I wasn’t directly controlling. The obvious, albeit cheesy, lava lamp came to mind, so I turned it on and went to work.

I connected a separate video camera via firewire, leaving a screen with all my interface controls available for me to tweak while recording. I recorded the video to MiniDV on the external camera, and as before recorded the output onto my PCM-D50 to free up the CPU for Reason and the GMS. Since I was recording the video on the external camera I had to the flip the video so that the image corresponded properly with the sound. This led me add a feature for toggling the mirroring in the GMS.

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.
