ABSTRACT:
A decoder assigns key values according to a system of mathematical weight values in terms of whole and semi-tone intervals of the musical scale, each key contributing its assigned value to the sum when depressed. Any interval along the scale can be reached by any combination of depressed keys that sum to that interval amount from the open "zero reference" position. The result is a woodwind-style keyboard that is perfectly regular and which has no default or unusable fingering combinations.
