SoundsCloud Flashback: Music for People on Shelves


I used Ableton Live to produce in real-time and my wavetable glitch machine Max patch to make most of the noises, which I routed into Live using Soundflower.

This five year old set is one of the very first things I ever posted on SoundCloud and it’s 86 minutes from a live solo performance with Minneapolis Art on Wheels. Checkout the original posts here:

Audiovisual Granular Synthesis of Water Objects

This is a screen capture from a Max project I developed that does interactive, synchronized, granular synthesis of corresponding sound and video that’s tentatively titled AVGM for Audiovisual Grain Machine. I have used the software during aperformance at the Echofluxx festival in Prague and at the Katherine E. Nash gallery for the opening of The Audible Edge exhibition during Northern Spark 2014.

Multitouch on a Mac without a Touchscreen


As you may have noticed it’s been a little quiet around here lately. The reason for this is that since the end of 2013 I have been keeping myself busy with a studio remodel (more on that later) followed by concentrating on preparations for a performance (I’m pleased to announce) at Echofluxx 14 in Prague, May 2014. Here’s a quick note about Echofluxx 13 from their site:

The Echofluxx 13 is a festival of new media, visual art, and experimental music produced by Efemera of Prague with Anja Kaufmann and Dan Senn, co-directors. In cooperation with Sylva Smejkalová and early reflections, the Prague music school (HAMU), and Academy of Fine Arts (AVU), Echofluxx 13 will present international and Czech presenters in a five-day festival at the Tracfačka Arena in Prague, Kurta Konráda 1, Prague 9, May 7-11, 2013.

I’ll discuss more details about this upcoming performance in another post. For now I would like to bring attention to the possibility of using the Mac trackpad and/or Apple’s Magic Trackpad for multitouch. My performance at Echofluxx involves using custom built software to loop granular audiovisual media. This idea evolved from projects in the past that used a 32″ touchscreen. This time the media will be projected, so I naturally decided to use the iPad as the controller. I built the project using Cycling ’74 Max and MIRA, which was very convenient, but I couldn’t get over the latency using the iPad over WiFi for multitouch controls.

I decided that the most convenient alternative would be to use the trackpad on the Mac laptop. Max has an object called “mousestate” that polls button-status and cursor-position information from the default pointer device. However, it is not designed to take advantage of multitouch data. This is where Fingerpinger comes in. Fingerpinger was able to detect ten independent touch points (perhaps more but I was out of fingers) on the built in trackpad on my MacBook Pro. Which begs the question; how did I take that screenshot?

Ten touchpoints on such a small surface is probably impractical, but I only need two; one for X-Y data and a second one for volume. Most importantly I wanted the audiovisual content to be activated simply by touching the trackpad rather than having to click or hold down a key. Fortunately Fingerpinger has a state value for each touchpoint that I was able to use to activate on touch and release. The latency is hardly noticeable compared to an iPad over WiFi, and I have also simplified my setup meaning I can travel with less equipment and rely on fewer technologies. I still like the idea of using an iPad for multitouch controls, mostly because of the opportunities for visual feedback. But for this particular application Fingerpinger is a great solution.

Machine Machine Touchscreen Instrument

Machine Machine (2013) is a 32″ touchscreen installation that functions as an electronic instrument. Granular synthesis is used to loop “grains” of sound and video at variable lengths and frequencies. These parameters are based on the y-axis of the touch point on the monitor. The x-axis determines the position of the grain within the timeline. The piece was exhibited last month at the Northrup King Building in Minneapolis during Art-a-Whirl and for Visual Storage; the MCAD MFA thesis exhibition.

Wired: Installation lets you remix actor’s face and voice

On Wednesday, November 16, 2011, Olivia Solon of wrote an article describing my piece, Voice Lessons. I have to thank for this one. Olivia found the article about my piece there and then emailed me to ask for a brief interview. We conducted the interview over email and the article was published the next day. Read the article by Filip Visnjic on Creative Applications Network. Read the article from Olivia Solon on Wired. Thanks, Filip and Olivia!
