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 electromagnetic valves of the air pipes (2), characterized in that it also provides for:
- providing a temperature sensor (6) in the proximity of a set of air pipes (2) and providing a sound detector (7) in one of the air pipes, both the temperature sensor (6) and the sound detector (7) interfaced with an 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);
- transmitting electrical information from the sound detector (7) to the ATS block (4) related to the sound generated by the corresponding air pipe when used during the execution of a music piece;
- transmitting electrical information from the temperature detector (6) to the ATS block (4) related to the temperature detected in the proximity of the set of air pipes (2);
- validating 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 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 sorting of the sound frequency value by the timer, after suitable conversion into a MIDI code towards the electronic organ (1) for tuning purposes;
- transmitting of data extracted from the frequency to temperature conversion table towards the timer that converts it said data into MIDI code and sends said data to the electronic organ (1) to tune the organ (1), if data about the frequency detected in the specific air pipe has not been received for a pre-established period of time;
- and
- automatically resetting of the timer, with consequence reset of calculation of the pre-established time period every time the timer receives the frequency value detected in the air pipe being monitored.
