Hello Rhythms & Melodies and welcome to the Beat Note community! Thanks for contributing.

Please add your vote and share your feedback by answering the questions on this request for midi export: https://roadmap.beat-note.app/feature-requests/p/export-to-midi

What do you mean by "sample library"? Please be as detailed as possible with what you would like to see.

There's one request for users to be able to add their own samples: https://roadmap.beat-note.app/feature-requests/p/ability-to-add-our-own-wav-drum-samples

As well as another request for having different kinds of drum kits for playback: https://roadmap.beat-note.app/feature-requests/p/multiple-drum-kit-playback-sample-templates

Do either of these match your request? 🤔

Thanks for supporting Beat Note! Best, Derek
