Electronic synchronizer for musical instrument and other kind of instrument and method for synchronizing auxiliary equipment with musical instrument
First Claim
1. A synchronizer for synchronizing a kind of instrument used for a purpose different from music with another kind of instrument used for producing a series of tones, comprising:
- a first data source storing a first piece of sequence data including pieces of synchronous data at intervals in a first data group and a second piece of sequence data including pieces of music data in a second data group and available for said another kind of instrument in order to produce another series of tones, and synchronously outputting said first piece of sequence data and said second piece of sequence data;
a second data source successively outputting pieces of reference data representative of an actual performance;
a converter for converting said pieces of music data to instructions for tasks to be achieved by said kind of instrument;
a first controller connected to said first data source, said second data source and said converter, and comparing said pieces of synchronous data with certain pieces of reference data corresponding thereto for transferring said pieces of music data to said converter in synchronism with said certain pieces of reference data; and
a second controller connected to said converter and said kind of instrument, and driving said kind of instrument in response to said instructions.

Abstract
An electronic synchronizer stores MIDI music data codes in a principal melody track and other MIDI music data codes in an external control track, and compares music data codes representative of depressed keys with the MIDI music data codes in the principal melody track to see whether or not the keys are timely depressed for producing the principal melody for reading out the other MIDI music data codes in the external control track in synchronism with the fingering, wherein the MIDI music data codes in the external control track are converted to instructions for an audio-visual system so that the electronic synchronizer achieves the synchronization between the fingering and the audio-visual system on the basis of the MIDI music data codes.

18. A method for synchronizing a kind of instrument used for a purpose different from music with another kind of instrument used for producing a series of tones, comprising the steps of:
-
a) preparing a first piece of sequence data including pieces of synchronous data and stored at intervals in a first data group and a second piece of sequence data including pieces of music data, stored in a second data group and available for said another kind of instrument in order to produce another series of tones;
b) receiving one of pieces of reference data;
c) comparing said one of pieces of reference data with one of said pieces of synchronous data to see whether or not said one of pieces of reference data arrives within a predetermined time period around a target time when said one of said pieces of synchronous data is to be processed;
d) transferring associated one of said pieces of music data to a converter in synchronism with said one of said pieces of reference data for converting said associated one of said pieces of music data to instructions for said kind of instrument when the answer in said step c) is given affirmative;
e) controlling said kind of instrument in accordance with said instructions; and
f) repeating said steps b), c), d) and e) for each of the remaining pieces of reference data. - View Dependent Claims (19, 20)
