So apparently, there are some volume problems with Datum, and a lot of the music came out very quiet, certainly much quieter than I intended. This is due to my change in software partway through writing the album. I’ve learned now how to resolve the issue, so that won’t happen again. I’m working on fixing it.

Yes, I noticed that whenever I listened to Datum, I usually found myself turning the sound up, otherwise it sounded fine. Surely the sound quality was ok though?
