Patent val: Difference between revisions
this link is particularly bad, because it leads to mutual dependency in defining each of the terms, the link could appear in this article (maybe at the end), but not in the definition |
fix error: it's "rounded" not "rounded off" |

The '''patent val''' (aka '''nearest edomapping''') for some EDO is the val that you obtain by finding the closest rounded | The '''patent val''' (aka '''nearest edomapping''') for some EDO is the val that you obtain by finding the closest rounded approximation to each [[prime]] in the tuning. For example, the patent val for 17-EDO is <17 27 39|, indicating that the closest mapping for 2/1 is 17 steps, the closest mapping for 3/1 is 27 steps, and the closest mapping for 5/1 is 39 steps. This means, if octaves are pure, that 3/2 is 706 cents, which is what you get if you round off 3/2 to the closest location in 17-equal, and that 5/4 is 353 cents, which is what you get is you round off 5/4 to the closest location in 17-equal. | ||
