Musical note playing pipe organ, has computing unit receiving input information from keys of keyboard by deducing sound patches by expression table pre-established by organist such that patches are associated with keys for executed piece

摘要

The organ has a set of pipes (109) producing a sound in response to supply of low pressurized gas at ends of the pipes. The pipes are supplied with pressurized gas by valves (112). Electric power supply of electromagnets (113) is managed by using a computing unit (114). The computing unit receives input information from keys of a keyboard by deducing sound patches by an expression table pre-established by an organist such that the patches are associated to the keys for an executed piece. The computing unit calculates the position of the valves to be operated.
