Crosstalk is a "duet for pianist and piano". The performer plays a piano part live (on a MIDI-enabled piano) from notation, and the MIDI output is sent to a laptop running Max MSP. The Max patch running on the laptop analyzes the realtime input and uses it to trigger the second part of the duet, which is played on another (virtual) piano. Crosstalk was commissioned as the score to a live dance piece choreographed by Nancy Karp; it was premiered by Nancy Karp + Dancers at the WestWave Dance Festival in San Francisco in 2007. Live keyboard was played by Marja Mutru; Max programming was by Barry Threw.

NOTE: The live human piano performance is stereo left and the Max piano is stereo right.
