It is possible for an electronic instrument to rely heavily on acoustic information as its primary source of audio and control signals. In effect, it can function as an extender and expander of the acoustic phenomena. When employed in this mode, the electronic instrument's expressive capabilities are greatly enhanced. This is true primarily because the physical coupling between performers and conventional instruments is more highly developed than it is with performers and electronic instruments. Conventional instruments and their performance techniques have long histories.
Refinement requires time.
Electronic instrumentalists are working with a performance history dating back only to the early 1960s. In fact, the notion of live performance was not considered very seriously until the early 1970s. It is in the nature of the exploratory process to probe the limits of a field. The process always uncovers much that requires further attention. The resourcefulness of the explorer often leads to temporary and makeshift solutions to previously unknown problems.
