This invention allows for easy field-customization of mainstream and
exotic electronic musical instruments, in isolation or in support of the
easy creation of aggregated instruments. The invention further
facilitates entirely new manufacturing, marketing, and sales paradigms
permitting a broad range of open industry development and commerce, thus
making an individual musician's creation of new exotic instrument
arrangements an economically viable sector for both mass manufacturing
and the niche cottage industry. New opportunities are provided for the
creation of multiple-vendor standardizations, multiple-vendor
manufacturing, multiple-vendor competitive features, etc. while offering
the music equipment user and music industry as a whole access to an
extensive range of instrument customization, diversification, and
education. The principles of the invention thus create a rich environment
for instrument, user, feature, music, and market.
