ABSTRACT:
This invention relates to a key system for electronic musical instruments, comprising a key circuit for forming control signals and control circuits for transmitting sound signals in response to the control signals. The key circuit produces the control signals in dependence on the position of a key and/or on elapsed time after depression of the key. Coupling means forming part of each control circuit modifies transient characteristics of the control signals whereby each control circuit can transmit notes in such a way that they each have a different build-up time. This enables the instrument to make a sound similar to that produced by a conventional non-electronic instrument.
