New music: Holocene

holocene

I’ve spent the last couple of weeks in the studio going over the expanded set-up of my sawtooth/vocoder work, Goyder’s Line for an upcoming performance (see image below.) In addition to the original set-up, I’ve incorporated an Electroharmonix POG2, which is serves as a rich octave generator for my trusty Korg Monotribe.

Whilst going over the work, I decided to explore the potential of running a stable sawtooth waveform through the Goyder’s Line set-up with the incorporation of a slow sweeping sawtooth wave from the Monotribe, articulated by the harmonic depth of the POG2.  Once I had the desired initial state in place, I left it running for the next 45 minutes – occasionally adjusting the parameters of the units, so as to gradually evoke changes in the harmonic structure of the sound and overall texture.

The resulting work, Holocene can be listened to below.

The Vocoder is being controlled by two sawtooth waves generated in Max/MSP. These sawtooth waves are routed to the Vocoder as the Carrier and Modulation signals. 

The frequency value for the the sawtooth waves is produced by a light sensor which reads the fluctuating (single) value of reflected light in my studio space. Once received by a Serial~ object in Max/MSP, the first sawtooth frequency value remains unchanged whilst the second frequency value (Modulation signal) is multiplied by 3.51 resulting in a scaled frequency value. 

E.G: if the Carrier’s frequency value is 104Hz, the Modulation frequency value will be (104 * 3.51 = 365Hz) 

On the MicroKorg, a perfect fifth is held (E1-B1) and the incoming Carrier and Modulation signals undergo processing via an Electroharmonix Memoryman set to a reverberant delay setting with feedback which his gradually increased.
