Improving piano performance from a Notion music sheet

is there any user-friendly way to improve the default performance of a music sheet in Notion? (without editing each single note’s parameters). So far, I wrote a piano score, and export the resulting MP3 file. The quality is that of an improved midi file, but it still feels very much « computer generated ». Is there any Notion plugin that would help me do this job? Is there any built-in feature which I don’t know about? Should I export my work (in .mid) and use another tool to do so?

Many thx for your help,

Kind regards,

Julien
