Btw, Rob Say's nsp simulator is in equal temperament. I've discussed this with him and he agrees that it's less than ideal but it's neverthless a good starting point for beginners - which was what is was intended to be.
When it tells you that, for example, the G and D drones are in tune, the d is still slightly (2 cents) flat relative to the G, but the just increment is not available - next click and it's sharp. Add the B on the chanter to the "in tune" fifth and you get an equally tempered G major triad, which is OK on a percussion instrument like the piano, where inharmonicity (q.v.) is part of the basic sound anyway and the sound mercifully decays fairly rapidly, but it sounds jarring to the ears of, for example, a sensitive piper or string-player. I hope I can feel confident that Rob will not object to my taking his name in vain. CsĂrz P.S. Have any fiddlers/violinists out there wondered why it's so difficult to sound in tune in C major - especially if there are lots of double stops and chords (e.g. Paganini's 11th caprice to take an obvious example <g>)? It's because you have to decide at any point whether you want/need to be in tune with the G string or the E string. To be in tune with both, you have to temper (narrow) your fifths, and then the fifths sound rongue. The chord GEbe (open G, first finger E+b, open e) (not encountered in said caprice, btw) is impossible to get in tune unless you tweak the finger sharp as you pass from the E to the b. Anyone really interested should look up "syntonic comma" (which is the difference between five perfect fifths (= open strings of viola + violin) and two octaves and a pure major third). It's the reason why guitarists with sensitive ears are never happy with the tuning of the G and b strings (and why you can't tune the fifth fret harmonic on the b string to the fourth fret harmonic on the g string - although many try to!). Once you've got used to hearing/listening to pure intervals, you realise that these are by no means dry, academic, theoretical considerations. If you haven't yet acquired the taste, you have a treat in store. Go for it. I was actually born with just intonation ears - so my music teacher at school told me (or words to that effect).
