I like doing music production on the computer - and always had a midi keyboard on hand... but I rarely used it, as I can't play piano: I can tinker, and I get the basics of music theory and can play basic chords... but I always found it better to just program things I wanted directly. Then a friend game me a "you rock midi guitar": https://www.musiciansfriend.com/guitars/you-rock-guitar-2nd-... - it's basically a toy, but because I'm better and tinkering with a guitar than a piano, I use it so much more and the stuff I make is now much more "full" than I could do before.

I don't know why I didn't think of it earlier - sometimes just changing the form-factor helps a lot!
