Regarding Copyright:
The Copyright Act of 1976 that became effective on January 01, 1978 is what determines the current duration of a musical copyright. There have been several amendments enacted since January 1, 1978 that also affect the duration.
There are two categories.
Works Created on or after January 1, 1978
Works in Existence but Not Published or Copyrighted on January 1, 1978
With certain exceptions, works from both categories created on or after January 1, 1978: life plus 70 years or 95 or 120 years, depending on the nature of authorship.
This information was obtained at www.copyright.gov.

You also may want to contact Notes Norton, a member here on the forum because he creates Band in a Box midi styles based from Fake Books and has researched copyright issues and has successfully been doing so I believe since soon after the inception and release of BIAB.
