Abstract

Apparatus for reproducing music, either by playing or by printing a musical score. The music is recorded on a record medium, such as magnetic tape, which has at least one and no more than eight recording channels or tracks. Representations of the fundamentals of the individual notes of the music are recorded on the record medium without inclusion of representations of the harmonics of these notes. The reproducing apparatus, according to the invention, includes the combination of means for reading the representations of the fundamentals, means for decoding these representations and means for receiving the decoded representations and reproducing the musical notes.

Claims

1. Apparatus for reproducing music from a record of a musical composition, said record having at least one and no more than eight recording channels and having recorded, on a maximum of eight recording channels thereon, representations of the fundamentals of the musical notes of said composition encoded in serial form without inclusion of representations of the harmonics of said musical notes, said apparatus comprising, in combination:

a. means for reading said representations of the fundamentals of said musical notes from said record medium;

b. means, connected to said reading means, for decoding said fundamentals of said musical notes, said decoding means including;

1. means for periodically storing said fundamentals;

2. a plurality of output terminals; and

3. means for periodically gating out said fundamentals from said storage means to said output terminals, whereby the existence of each fundamental is represented by the presence or absence of a signal on a separate one of said output terminals; and

c. means, connected to said output terminals of said decoding means, for reproducing said musical notes.

2. The apparatus defined in claim 2, wherein said means for periodically storing said fundamentals includes:

i. a plurality of signal gates each having two input terminals and one output terminal, one of said input terminals of each of said gates being connected to receive a signal from said reading means;

ii. a plurality of storage elements, each connected to the output of a separate one of said signal gates; and

iii. scanning means, connected to the other of the input terminals of each of said signal gates, for gating individual ones of said signal gates in succession.

3. means for periodically gating out said fundamentals from said storage means to said output terminals, whereby the existence of each fundamental is represented by the presence or absence of a signal on a separate one of said output terminals;

and c. means, connected to said output terminals of said decoding means, for reproducing said musical notes.
