Abstract
The present invention refers to a method used to automatically tune, thanks to the presence of a suitably designed electronic device, an electronic organ with the air organ pipes associated with it; it being provided, in particular, that the said operation is performed based on the tuning variations detected in real time on the air pipes based on parameters referring to the frequency of the emitted sound and to environmental temperature.

Method used to tune an electronic organ with associated air pipes, of the type that makes use of an MPI block (5) for the Midi serial port that converts serial digital data from the organ (1) into electrical signals used to control the electromagnetic valves of the air pipes (2), characterized in that it also provides for
- application of a temperature sensor (6) in the proximity of a set of air pipes (2) and a sound detector (7) in one of the air pipes, both interfaced with the ATS block (4) together with the MPI block (5) in an electronic device positioned between the set of air pipes (2) and the electronic organ (1)
- transmission from the sound detector (7) of electrical information towards the ATS block (4) related to the sound generated by the corresponding air pipe when used during the execution of a music piece
- transmission from the temperature sensor (6) of electrical information towards the ATS block (4) related to the temperature detected in the proximity of the set of air pipes (2)
- validation and processing of the electrical signal related to the sound of the air pipe by the ATS block (4) to determine frequency
- use of the sound frequency value, in combination with the value of the temperature gradually detected by the sensor (6) in order to create a temperature to frequency conversion table in real time
- timing of the sound frequency value by a timer provided in the ATS block (4) and data sorting by the timer, after suitable conversion into a Midi code towards the electronic organ (1) for tuning purposes
- transmission of data extracted from the frequency to temperature conversion table towards the timer that converts it into Midi code and sends it towards the electronic organ (1) to tune the organ (1), if no data about the frequency detected in the specific air pipe has not been received for a pre-established period of time
- automatic reset of the timer, with consequence reset of calculation of the aforementioned time period every time the timer receives the frequency value detected in the air pipe being monitored.
Electronic device used for the implementation of a method used to tune an electronic organ with air organ pipes associated with it, characterised in that is consists in an ATS block (4) capable of automatically managing the operations described in the aforementioned claims.
