Can I distribute music with limbo/ without giving up my rights?

Yes. limbo/ is the technology layer behind your distribution, not a label or a rights buyer. Your masters, your catalog and your metadata stay yours; distributing with limbo/ never gives limbo/ a share of your rights or your copyrights. Selling is a separate decision, and only yours: if you want to sell your catalog, limbo/ works with funding partners who buy catalogs or give advances against your royalties that recoup over time. Your royalty data stays private and is never shared with major labels. See how distribution works.
