It's interesting seeing parts of life overlap.
I did music production at the same time as heavily using SVN and starting to use Git - I didn't cross this over at the time. All (in my case) Cubebase files were just -1, -2 suffixes and it worked. I had continuous backups, sure and it just kinda worked at the time.
Given I now use Git heavily in my work/hobby life, when doing other projects (3D models for printing (questionable at best) and artwork (very very very questionable at best)) I definitely wanted to use some sort of SCM. I opted for these for Perforce - mostly to experiment, but also the idea of having binaries in a distributed SCM. Yes, I know Git-LFS _exists_, but also, to me it breaks the idea of what Git is.. relying on a server for binaries in a situations where everything should be distributed.
If I now went back to audio-production, I would probably consider either Perforce or SVN. Perforce only if it were for a single user (because of licensing). The ability to clone/checkout a single directory of a repo at a given point in time natively and make modifications and push them back is almost quite necessary when dealing with very large files.
And I still use SVN for _some_ situations - particularly those where Perforce is overkill and all I want to _always_ HEAD and the rest is history (for manual preservation history) and no such need for merging and branching (thinking Wiki and other plain-text tooling).
In the case of any sort of any binary-merging - I _heavily_ assume this isn't expected in the poster's situation!
