Music composition aid
Disclosed herein are computer-implemented method, computer-readable storage medium, and DAW embodiments for implementing a music composition aid. An embodiment includes retrieving a first constraint value, receiving a selection of a set of musical elements, and accepting a second constraint value corresponding to the set of musical elements. Some embodiments further include invoking an iterator function, using at least the second constraint value as an argument, and generating an output of the iterator function, limiting a size of the output of the iterator function, according to the lesser of the first constraint value or a transform of the second constraint value. Output of the iterator function may include, of the set of musical elements, a subset determined by the second constraint value. The size of the output may be no more than the first constraint value. Further embodiments may render the output of the iterator function visually and/or audibly, for example.
1. A computer-implemented method, comprising:
retrieving, by at least one computer processor, via a memory, a first constraint value;
receiving, by the at least one computer processor, a selection of a set of musical elements;
accepting, by the at least one computer processor, a second constraint value corresponding to the set of musical elements;
invoking, by the at least one computer processor, an iterator function, using at least the second constraint value as an argument;
generating, by the at least one computer processor, an output of the iterator function, wherein the output of the iterator function comprises at least part of a subset of the set of musical elements, wherein the subset is determined by the second constraint value;
limiting, by the at least one computer processor, a size of the output of the iterator function, according to the lesser of the first constraint value or a transform of the second constraint value, wherein the size of the output is less than or equal to the first constraint value;
rendering, by the at least one computer processor, the output of the iterator function.
2. A non-transitory computer-readable storage medium comprising instructions stored thereon that, when executed by at least one computer processor, cause the at least one computer processor to perform operations comprising:
retrieving, via a memory, a first constraint value;
receiving a selection of a set of musical elements;
accepting a second constraint value corresponding to the set of musical elements;
invoking an iterator function, using at least the second constraint value as an argument;
generating an output of the iterator function, wherein the output of the iterator function comprises at least part of a subset of the set of musical elements, wherein the subset is determined by the second constraint value;
limiting a size of the output of the iterator function, according to the lesser of the first constraint value or a transform of the second constraint value, wherein the size of the output is less than or equal to the first constraint value;
rendering the output of the iterator function.
