Properly, one should write out the generators or step ratios of all the input edo tunings, for example <code>5L 2s (7\12||11\19)</code> or <code>5L 2s ((2:1)||(3:2))</code> Less carefully, we can also use just the edo numbers: <code>5L 2s (12||19)</code> (but there is potential for confusion when an edo has multiple tunings of a given scale structure). | Properly, one should write out the generators or step ratios of all the input edo tunings, for example <code>5L 2s (7\12||11\19)</code> or <code>5L 2s ((2:1)||(3:2))</code>.

This works similarly for rank-3 and higher scales: for example, <code>diasem(7||26||31)</code> specifies the mediant hull of the 7edo (L:m:s = 1:1:0), [[26edo]] (L:m:s = 4:2:1) and [[31edo]] (L:m:s = 5:2:1) tunings for [[diasem]]. | This works similarly for rank-3 and higher scales: for example, <code>diasem(7||26||31)</code> specifies the mediant hull of the 7edo (L:m:s = 1:1:0), [[26edo]] (L:m:s = 4:2:1) and [[31edo]] (L:m:s = 5:2:1) tunings for [[diasem]]. | ||
