You can also start from the [[http://x31eq.com/temper/uv.html|unison vector search]] page. In this case, you get a box telling you to put your commas in the box. For a rank two temperament with a prime limit containing n primes, you need to put in n-2 commas. For instance, in the 7-limit there are four primes, 2, 3, 5, and 7. Putting in 4-2=2 7-limit commas will work: for instance putting in 50/49 and 64/63 and scrolling down to rank two temperaments we see pajara again. | You can also start from the [[http://x31eq.com/temper/uv.html|unison vector search]] page.

Now take the two numbers you obtained from the temperament finder, and start [[Scala]]. In the box at the bottom of the screen, type in "lineartemp". It will ask for a size; enter the number of steps you want in your scale, divided by n, the number of periods in an octave. For instance if you want ten steps, and are using the pajara generators we obtained, put in 5. Then it says "enter formal octave (2/1)". Put in the period, making sure to include the decimal point. That is, put in 598.859 if you want to use octave compression; otherwise put in 600.0. Now it will say "enter fifth degree, 0 for monotonic scale [0]" and you hit return. Then it will say "enter formal fifth [$0]", and you enter the correct generator. For instance, if before you had entered 600.0, now you enter 107.48 to go with it. Then it says "enter count downwards" and again you can just hit return, or you might try putting in a positive integer and seeing where that gets you. | Another starting point, of course, is this wiki. In an article on the temperament, find the POTE generator listing; you may use that. You also can look at [[edo]] tunings; in N-edo you may find g\N as a generator tuning, meaning g steps of N-edo, or the g/N fraction of an octave. | ||

If you have an edo tuning in the form g\N, you can enter 2^g\N (with no parentheses around "g\N") as the formal fifth. | |||
Next, if the number of periods in an octave "n" was greater than 1, type in "extend m" at the bottom, where m is however many steps you want in an octave; it should be n times the number you entered when it asked for size. In this case, we entered 5 for size and n=2, so we type in "extend 10". | Next, if the number of periods in an octave "n" was greater than 1, type in "extend m" at the bottom, where m is however many steps you want in an octave; it should be n times the number you entered when it asked for size.
