In the summer of 2007, multi-talented artist and researcher visited JazzMutant’s HQ to share with the Lemur’s creators some of his experiments with the multi-touch controller. This resulted in a series of outstanding and playful real-time video performance instruments.

Created with Cycling 74’s powerful Max/Jitter programming environment, these applications involve various video manipulation techniques such as sampling, looping, filtering and blending. Each example contains the original Max/Jitter patch, the associated external objects, a .jzml JazzEditor file as well as Mac standalones for the first three instruments. Your webcam can be used as a video input…


This patch is a real-time, lemur-controlled instrument for recording and exploring video material in a video-delay line.

Some important concepts are:

  • use of the lemur’s physically modelled movements of interface objects to get very smooth back-and-forth looping of small sections in the video delay line

  • use of a variety of inter-frame video interpolation techniques to get smooth video even when the time-scale is very very very slow

This patch is a real-time, lemur-controlled implementation of the “time-cube”, or “khronos projector.” The idea is that we are presented with a 2-D image, whose 3rd dimension is TIME. The performer is then able to “dip into the past” in whatever area of the image he/she pleases, by creating a “time-window” in that area. This particular implementation allows one to use real-time input (i.e. a camera) as the source material.

This patch is a multi-voice video-loop recorder and player, made for real-time input from a camera and real-time control from the Lemur.

Some random details:

  • background substitution is used to isolate actor in the recording

  • the lemur allows the performer to record, and place each video loop in the rendered space

The bottom line of this patch is, a structure made of masses and springs, whose behavior over time is simulated with ” “, and whose real-time parameters are controlled from the lemur. The lemur interface allows the performer to control many of the parameters of the physical modeling simulation (like the position of one of the masses, the ridgidity of the springs, the dampening of the springs, the speed of the simulation…). This in turn allows the performer to attain a wide range of behaviors from the structure. In other words, the performer makes the structure dance.
