3 improvisations for saxophone and interactive computer
Below is a link to a live performance on Schism (by Randall Hall, saxophone). The video is in two parts. Please note that there are many possible versions of this piece as it is improvisatory in nature.

Schism (2003) is a set of three improvisations for saxophone and interactive computer. The major difference between "Schism" and many traditional works that combine live instruments with electronics is the fact that in these works the computer and the performer interact with one another in real time. Each piece consists of a collection of pitch materials and special effects that the saxophonist improvises freely with. The computer reacts to the saxophonist producing a series of sounds based on what the saxophonist plays. The computer is also capable of creating random elements throughout a work, thus allowing the saxophonist to react to the computer. The interactive computer environment is designed to maximize flexibility in performance to generate, layer, and route musical material with the same improvisational freedom that one might develop with a purely acoustic instrument. Thus, each performance of the piece will vary slightly.
The technical setup for "Schism" is relatively simple. One needs a saxophone, a microphone, a computer capable of running MAX/MSP, an audio interface with input and stereo output, and a pair of speakers.
Many of the sounds generated by the computer come directly from digital signal processing algorithms that manipulate the live sound from the saxophone. The saxophone sound (signal) is sent directly into the computer, where pitch, amplitude, and overtones are detected by the computer interface. Specified orders of pitches and/or extended techniques then determine the types of sounds that the computer will produce.
At the core of these pieces is the interface that I developed using the MAX/MSP environment. This interface coordinates MIDI continuous control messages from the signal data from the saxophone (pitch, amplitude, and overtone detection) - mapping them into real-time performance processes. The interface encompasses numerous palettes of live-sampled sounds, interactive compositional and mixing algorithms, and live digital signal processing algorithms for harmonization, modulation, comb filtering, various delays, and granular synthesis. Some of these digital signal processes draw on the PeRColate externals, a collection of MSP externals developed by Dan Trueman and Luke DuBois, with additional credit to Miller Puckette for his pitch and attack detection externals.
