There are a few websites that can separate stems. I use lalal.ai to get the bass line and then convert it to tabs using another service.
Unfortunately, if there’s any hope of lemmy really taking off, they’ll come eventually. All popular sites and services have to deal with it at some point.
Lots of customization options and yeah, it’s what we know. I’m comfortable with how the app organizes stuff and am happy to support the dev.
