Single-component output for multiple instruments

Develop a modification of n-generative rule-synchronized music grammar systems in which a single component can generate scores for multiple instruments—both cases where several instruments play the same music and where they play different parts—while preserving system-wide synchronization.

Background

In the presented framework, each component produces the score for exactly one instrument. The authors note that real orchestral writing often duplicates material across several instruments for long passages, suggesting potential redundancy in the current one-component-per-instrument design.

They explicitly ask whether the model can be altered so a single component can output multiple identical or distinct instrument lines, which would more closely reflect orchestrational practice and potentially simplify specifications.
