Driven by his interest in creating performer controlled sound processing environments for improvising acoustic musicians, he developed a major redesign of the Expanded Instrument System (EIS) for the Pauline Oliveros Foundation. He has designed variations of the EIS for teaching, demonstration, recording, and for use by guest musicians in performances with Deep Listening Band (with Pauline Oliveros and Stuart Dempster) of which he has been a member since 1990.
Gamper is also half (with photographer Gisela Gamper) of See Hear Now, a visible music sound and video projection duo, and hilde+ed productions, a multi-media content development partnership. He provided music for several of the displays at the Visitor Center at Arecibo Observatory in Puerto Rico. JdK Productions has released the recording of a January 1999 duo concert with Pauline Oliveros at The IJsbreker in Amsterdam. Also released by JdK is a compilation of the Whitney's Bistreams exhibition's sound artists, which includes his piece Conch. He appears on many other CDs with Deep Listening Band and others. Recently released is a DVD with See Hear Now.
