This element represents one rank of a mixture, a rank which has the same scale and pitch. A mixture with breaks will have more MixtureRank elements than the number of simultaneously sounding ranks in the mixture. For example, consider the following 3-rank mixture:

This mixture is considered to have three ranks, because three pipes sound for each note. However, seven MixtureRank elements are required to represent it, because the mixture contains seven different pitches. See the example below.

Composition

Name	How Many	Description
Remark	(zero or more)	remarks about this MixtureRank.
Scale	(zero or more)	contains scaling information for this rank.

from   (required)

The starting (lowest) note of the rank, inclusive. The value of this attribute must conform to the standard for Note Names.

to   (required)

The ending (highest) note of the rank, inclusive. The value of this attribute must conform to the standard for Note Names.

pitch   (required)

A number representing the pitch of the rank, possibly including a fraction. The fractional portion must be separated from the whole-number portion with a hyphen. The pitch is that which the lowest pipe in the rank would have if it extended down to the bottom of the keyboard.

The following example shows a representation of the mixture described above.

<Stop name="Acuta" ranks="3">
    <Composition>
        <MixtureRank from="CC"  to="B"    pitch="2/3">   </MixtureRank>
        <MixtureRank from="CC"  to="B"    pitch="4/5">   </MixtureRank>
        <MixtureRank from="CC"  to="b"    pitch="1">     </MixtureRank>
        <MixtureRank from="c"   to="b'"   pitch="1-1/3"> </MixtureRank>
        <MixtureRank from="c"   to="c'''" pitch="1-3/5"> </MixtureRank>
        <MixtureRank from="c'"  to="c'''" pitch="2">     </MixtureRank>
        <MixtureRank from="c''" to="c'''" pitch="2-2/3"> </MixtureRank>
