Key pressure simulator for electronic keyboard instruments

摘要

To make it possible to create a tone and chord sequence memory device as additional device for electronic keyboard instruments, which, in contrast to known devices, is primarily distinguished by being universally applicable together with keyboard instruments of various manufacturers and by more efficient possibilities of processing the memory content, the key pressure simulator utilizes the existence of key contacts, common to all electronic keyboard instruments. The manual key pressure is simulated by remote-controlled operation of electronic switching elements which replace or bypass the existing key contacts.
