Yeah, I pretty much use ppmck for nes stuff, though I really do want to at least delve a little more into Famitracker. I am actually able to use the basics though it's painful. One of these days when I become more familiar with it, I should make tutorials or something. It can be done as a blind person, but only with about 500 barrels full of patience. Accessibility challenges really do hold a blind user back, so at present, I'd only recommend it for those who are curious, not for those who expect quick results. Open MPT, another music tracker, is fun to mess with as well, though again it's a tracker so needs 500 barrels of patience.
Other chiptune programs: xpmck as was mentioned. Also I recently found a Japanese mml program for the Konami MSX, I think it's called mgsc. It supports the psg, wavetable and fm chips, can't remember the chip model numbers but by the looks of it, its support for msx sound is far greater than xpmck is at present. Unfortunately, documentation is in Japanese. I haven't really tried to work out what everything does. One of these days I will, though, because the combination of chips is intriguing to me.
Also for Snes, there's a program called AddmusicK. It's literally MML for the Snes (something which I thought would never happen) and I think it's pretty dang cool. Its main purpose is to make music for Super Mario World romhacks, but it's fairly easy to strip all the Super Mario World stuff out and just make spc files.
Make more of less, that way you won't make less of more!
