What is Derivative's contribution to the Plastikman Live 2010 Tour?
(among other things…)
1. We are building a bridge between Ableton Live and Derivative’s TouchDesigner, where TouchDesigner is aware of a lot of Live’s information, which can be used by the visual artists to make moving pictures.
Derivative will release the TouchDesigner-Live Bridge to its users in the first half of this year.
The data Ableton shares with TouchDesigner includes controllers, what loops are playing, clocks, show sequencing and transitions between tracks, raw audio, and outputs coming from audio effects.
2. We’re building a working environment for Ali Demirel and other artists who are designing and building visuals for this show, where each person can easily hook the Ableton signals to their visual in TouchDesigner. It’s as if each track has its own cocoon to operate in.
( Ali and the others build the visuals and choose the hookups - what part of the visual hooks up with what part of the music, and the sync with Ableton is done already. )
3. We are also building with TouchDesigner panel-building tools a flexible user interface for Ali Demirel to use during the show. He’s Richie Hawtin's co-pilot essentially, guiding some aspects of the visual from front-of-house.
One of Ali’s controllers is a Jazzmutant Lemur (Rich too) and it feeds its multi-touch outputs into TouchDesigner as well.
We think the TouchDesigner-Live Bridge will be useful to artists doing visuals alongside Live – we will release this bridge along with some know-how.
What has changed since the last Derivative-Plastikman collaboration in 2004?
Using MIDI to do a complex show control was all we had at the time, but today we have TouchDesigner supporting OSC (the Open Sound Control protocol over Ethernet), and Ableton now supports OSC through its MAX4Live plugin. This makes it a lot easier for the Live artist and the visual artist to work together and rapidly evolve a show.
We are now using TouchDesigner’s newly-architected image processing, effects and compositing system called Texture Operators, or TOPs. TOPs, are image operators that provide real-time, GPU-based compositing and image manipulation.
In fact, we have fully-re-designed TouchDesigner’s user interface with zoomable networks and viewers on every node. It is a visually very rich authoring tool for making any kind of interactive art.
( And its new modular component architecture allows reuse and cloning of mini-tools…)
