Hi Darrel, since you're new to UC, allow me to mention my discography of piano-and-orchestra works, the short version of which is online at https://www.siue.edu/~aho/discography/Discography.pdf. This will let you know if a recording exists of a particular work (note: underlined works are in electronic rather than real performances). My full discography (offline) includes record/CD labels, performers, sources, etc.; I am happy to provide additional information as needed. This will save you from preparing midi versions of works that have already been recorded in some form. I look forward to your future uploads.
