AVGM: Rheology

Here’s another movement from my composition Vocalise Sintetica that I performed at Echofluxx in Prague and later during Northern Spark 2014. I named the movement Rheology after the study of the flow of matter in the liquid state. The audiovisual content was created with a Max patch I developed called AVGM (AV Grain Machine). The instruments that I used to create the accompaniment include: DSI Tempest, Bass Station II, Korg Volca Keys, and Memory Man Delay.

AVGM with Tempest, BSII, and Volca Keys

During Northern Spark 2014 I performed a version of Vocalise Sintetica at the Katherine E. Nash Gallery. The event, timed with Northern Spark 2014, also marked the opening of The Audible Edge (May 27 through July 26, 2014), a sound art exhibit of which I am also taking part. Since it was a local performance I decided to introduce the DSI Tempest into the setup (along with the Bass Station II, Korg Volca Keys, and Memory Man Delay).

This led me in a completely different direction than the performance in Prague. I was quite happy with the results so I produced a few studio versions of alternative movements. For these videos I made a screen capture of the AVGM (Audiovisual Grain Machine) and interspersed shots of the instrumentation. Here’s the the first alternative movement of I. Machines. I hope to post a couple more movements at a later date. View photos from the performance below.

Vocalise Sintetica at Echofluxx 14, Prague

On May 7, 2014 I performed Vocalise Sintetica at the Echofluxx Festival in Prague. The piece is made up of four movements: I. Machines (00:00), II. Liquid (18:43), III. Vocalise (28:55), and, IV. Sintetica (38:41). Each movement is a playlist of five audiovisual objects that are instantly available to be projected and amplified while being granulated in real-time by a performer using a multitouch interface. The performer may loop their gestures applied to the audiovisual objects in order to bring in additional synthesized sound layers that contrast or mimic the audiovisual objects. My performance at Echofluxx was made possible by a grant from the American Composers Forum with funds provided by the Jerome Foundation.

Audiovisual Grain Machine Demo

Here’s a quick demo of the software I am designing to do audiovisual granular synthesis that I’ll be presenting at Moogfest and performing with at Echofluxx. It allows a performer to apply granular synthesis to sound and corresponding video using a touch interface such as MIRA (shown). The audio and video are synchronized in parallel. The software also has the capability to capture and repeat gestures so that the performer can accompany the projections with multiple layers and arrange compositions in a performance setting. This demo granulates the voice and image of Lister Rossel. In addition I use analogue synthesizers to contrast the digital manipulations.

This work alludes to the speech-to-song illusion discovered by Diana Deutsch. It also evokes an “event fusion” as vocalizations are repeated much faster than humanly possible until they enter the audio range. Adding the corresponding visuals makes it appear uncanny as video and sound are looped in millisecond intervals.
