I've written a few things here and there (mostly classical style piano sonatas)... a lot is done digitally to write and perfect things, then I'll play it on the piano for the master recording.
Though that's pending that I get that far, as a lot of my work is incomplete. Especially lately, as I haven't been able to play my piano (electric keyboard) as there's a problem in the audio output, and I can't find the right part to fix it. So I'm kind of stuck doing everything digitally for now.
I also play the guitar, though I'm not as proficient with it as I am with the piano.
