This page describes an advanced feature which few Unify users will need, and which is still somewhat experimental at the time of writing.
To use the techniques described here, you should be comfortable with creating and editing plain-text files.
Patch variations were introduced in Unify v1.6.0. Any patch can optionally include a reference to a plain-text “variations” file (kept in the library's Media folder), which is simply a list of “variation names”, one per line. The newly-added top-level parameter variation can be linked to a macro knob, and simply selects which of the variation names is displayed in white to the right of the patch name.
Patch variations can also be used in combination with one or more sample-maps in Guru Sampler, where the parameter osc1SampleSelect is linked to the same macro-knob as variation, and the names in the variations file correspond one-to-one with the available choices on the sample-select menu in Guru Sampler. Provided the lines in the variations file correspond one-to-one with the Guru Sampler sample-select menu choices, and the exact same response curves are used in both parameter links, the variation-name displayed in large white text at the top of the Unify GUI will always indicate which sample is selected in Guru Sampler, so it's not necessary to have the sampler GUI open to see it. This technique was first used in the Unify library PlugInGuru Chill GTR Phrases.
Here is an early draft of a variations file from the PlugInGuru Chill GTR Phrases library. This file is called Moody Chill GTR Phrases LIST.txt, and is placed in the library's Media folder.

The initial “All Samples” line is not actually used in this library, but it must be present in this file AND the corresponding sample-names list file (see below), because Guru Sampler always provides a default “all samples” option as the first choice on the sample-select menu.
Guru Sampler supports optional Sample-names list files sibling to .gsd or .sfz sample-map files (with the same file name, but extension .txt). These sample-names lists must correspond one-to-one with the available samples in the sample-map, plus an extra initial “all samples” entry.
Here is an example from the PlugInGuru Chill GTR Phrases library, a file called 120 Moody Chill GTR Phrases.txt (there are several, and their contents are identical) in the library's Samples folder.

Observe how these sample-names correspond one-to-one, to the names in the variations file, except there is no default “all samples” line at the start. This is because this is a list of sample names, not mapping options.
The exact text in the two files need not be the same; library author John Lehmkuhl has chosen the text to work well in the large variation-name display in the former case, vs. the small sample-select menu in the latter.
Here is an example of how one of the Unify macro knobs is linked to both the osc1SampleSelect parameter of a Guru Sampler instance, and the top-level (global) variation parameter, in the PlugInGuru Chill GTR Phrases library:
What's not immediately obvious in this screenshot is that the leftmost end of the response curve does not go all the way down to zero, because that would select the default “all samples” map, which is not used in this case. Instead, the leftmost point has been carefully positioned to select the second choice, which in this case is the single sample “Guitar Phrase #01 - Dm”. Then the curve is copy/pasted to the second link to variation.
