I don't always have any of my keyboards handy whenever I get a melody running through my head, so what I like to do is use my computer (desktop, laptop, or tablet) to enter the notes into a music notation software program. My favorite program for ease of use is NCH Crescendo, which is free. And if I need to plonk on a few keys to figure out which notes I'm hearing in my head, I use the free VMPK (Virtual MIDI Piano Keyboard) program for that. The nice thing about this is that you can do it on a tablet PC while lying in bed (e.g., if you wake up in the middle of the night with a melody in your head), and you end up with actual sheet music. You don't necessarily need to enter in the entire song, just create a "lead sheet" containing the basic melody phrases-- i.e., enough so that when you do get to your keyboard(s) later you've got something to remind you what that catchy melody was that you couldn't get out of your head.
Nice one, Michael,
Sounds good, but let me tell ya, that wouldn't work for me. Soon as I plonk myself in front of a computer screen, my creative mojo logs off. :-(
I use one of these little old gems, long-since a discontinued model but still does for me: Olympus DS-330 digital dictation recorder.
Snapped up two of 'em for fifteen UK pounds some time back on a resale site: Still see a few of 'em up for sale, even now after twelve years or so.
Forget high-quality audio, (it's a dictaphone, see: cross between a bad telephone line and a wind-up gramophone. There's no memory card, just 16MB flash memory, and forget about a Windows 7 link-up. (Why whip yourself)? I just use it as a standalone scratch pad to keep any quick ideas logged.
But here's the thing about this little recorder, and to me, it was like finding buried treasure: It includes in its editing functions: overwrite, append and INSERT, can you believe!
If you're a songwriter, lyricist, poet, you'll love those functions. Of course, both Yamaha and Olympus have their current, equivalent models: bigger, fancier and priced to make you gulp.
Doctors, lawyers and other posh punters praised the DS-330 highly back in 2003:

If you're wondering about the green duct tape, it's my finger hold modification. Makes it a true one-handed operation, whilst walking, lying in a hammock ...
cheers to all
