Thinking about resubscribing, advice please

Hi there, br
br
I subbed a long time ago and enjoyed the content. I know my way round Ableton, but generally struggle with my musical ability. I can never get a melody or baseline to sound right without copying it and have never really bothered with learning music theory.br
br
Is resubscribing a good idea? Do the newer courses contain bits about music theory and how to get things in key etc or am I better focusing my time elsewhere for now to learn?br

I know this sounds a bit like “teach me how to be a musician”, but I love music and tinkering with sound design I just need to bring it all together a bit more. Unless its basic beats and percussive stuff I can’t really get that extra bit further.
