Bass Station II Through the Minifooger Delay

IMG_20140429_155228

I finally got my hands on a Minifooger Delay by Moog. I wanted something battery operated and more portable than the Memory Man for my performance at Echofluxx.org on May 7th, 2014 and an upcoming recording project in Northern England. Lucky for me it showed up at Foxtone Music just days before my flight to Prague. Thanks, Eric!

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.

Wall of Synth Part 2: Tempest, BSII, Volca Keys, Juno-106, MKS-80, D-50

This is another example of using the Korg Volca Keys as a sequencer for the Juno-106. Also featured are the Roland Super Jupiter MKS-80, Roland D-50, Novation Bass Station II, and DSI Tempest. Again, I set limitations on my process. I composed the piece with no overdubbing. All tracks were recorded simultaneously. Post-production was limited to editing for length, fades, and one reverb send.

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.
