The laptop orchestra is a socially charged context for making music together with new digital instruments while simultaneously developing those instruments. As the role of the performer and builder have merged and the speed with which instruments can be created and revised has increased, the development of musical instruments has become part of the performance of music.

In Figure 2, the instrument is "exploded" to reveal the components that might make up a digital musical instrument. Traveling along the feedback loop in Figure 2, we can see relevant challenges, including sensor design and configuration, haptic feedback systems, computational problems with feature extraction, mapping and synthesis, and amplifier and speaker design.

, integrates speaker and sensor technology directly into acoustic resonators so thoroughly that, at first glance, it is not apparent that these are not simply acoustic instruments (Figure 5)

Although the importance of haptic feedback remains an open question, I am convinced it will become more important and more highly valued as digital musical instrument design technologies continue to improve. The physical feedback a violinist receives through the bow and strings is very important to his/her performance technique, as well as to the sheer enjoyment of playing.

In fact, the mapping layer itself can be dynamic, changing as the instrument is played. As described earlier, however, creating mappings by manually connecting features to synthesis parameters is always challenging, sometimes practically impos sible.

Rather than optimal solu tions to well defined problems, they reflect individual and cultural values and are ongoing ad hoc manifestations of a social activity that challenges our musical and engineering abilities simultaneously. Musical instruments frame our ability to hear and imagine music, and while they enable human expression and com munication, they also are, in and of themselves, expressive and communicative.
