[LAU] csound help

I am trying to prepare a lecture on scales. If a is say 440 Hz and r is 12th root of 2 then the usual equal tempered scale would be a ar^2 ar^4 ar^5 ar^7 ar^9 ar^11 ar^12 = 2a What if we change r to 7th root of 2 and replace the powers 2 4 5 7 9 11 12 by 1 2 3 4 5 6 7? I expect it will sound nonsensical but I really dont know... I want to show these kind of experiments on the computer. Is csound is a good starting place to try? Are there any toots/templates etc for such? Also which opcodes should I concentrate on? [For me its been a few days of rummaging around and Ive got out a sine wave. I expect that the actual code will be about 3-4 lines for an instrument and 2 lines for a and ar^2 after which I can fill in the blanks. So for a csound expert it should be 5 minutes. Yes I am being a bit lazy in asking :-) ]
