However, the first example includes a link to a //.guru// file you can download and try, even before you understand all the details. 
 + 
 +**Important Note:** when loading a patch from a library, Unify always expects to find the variations-list file in //that library's own Media folder//. This means, if you re-save a patch into a different library, you will need to copy the original variations-list file into that library's //Media// folder (and you may need to create the folder, if there isn't one already). **This is a limitation in Unify v1.6.x.** It may be fixed in a future update, but this is not guaranteed.

-===== Concept of patch variations =====+===== Basic Concept =====
  
 //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 [[param-paths#top-level_paths|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// were introduced in Unify v1.6.0.

 ===== Example 1: Song sections ===== ===== Example 1: Song sections =====
 +One very good use of patch variations is for patches containing one embedded-Unify INST layer for each part of a performance (e.g. Intro, Verse, Chorus), which are selectively enabled via //midiEnable// parameters linked to a macro knob. As the knob is turned, the layers are enabled one at a time, and the variation-text at the top of the GUI changes to match.

 +
 +==== Variations file ====
 +For this example, the variations-list file (//Intro_Verse_Chorus.txt//, found in the //Media// sub-folder of the //User Library// folder) is very simple, consisting of just three lines:
 +
 +<code>
 +Intro
 +Verse
 +Chorus
 +</code>
 +
 +==== Parameter links ====
 +In the example //3 Parts Song Switcher// patch, macro knob #8 has been set up with some carefully-crafted links so that as the knob is turned, the layers are enabled one at a time, and the variation-text at the top of the GUI changes accordingly. Here is what the links look like:
 +
 +{{::variations-3.png?300|}} {{::variations-4.png?300|}} {{::variations-5.png?300|}} {{::variations-6.png?300|}}
 +
 +The stairstep response-curves were not made by hand, but were generated mathematically. The download link below in the next section includes these, in the form of macro-link curve presets.
 +
 +==== Example downloads ====
 +
 +Clicking the following link downloads a zipped [[guru-files|.guru file]] which installs a single new patch called //3 Parts Song Switcher// into your //User Library//, all set up in this way, including variations.
 +
 +{{ :unify_step_curves.zip |}}
 +
 +This //.guru// file also installs the special "stairstep" curve presets into the correct folder, so they're ready to use in your own patches.
 +
 +These special curves were generated using a [[https://www.python.org/|Python program]], which you can also download here:
 +
 +{{ ::generate-step-curves.zip |}}
  
 +Both of these downloads are //.zip// files; you will have to unzip them after downloading.

 Patch variations can also be used in combination with one or more sample-maps in [[guru-sampler|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//. Patch variations can also be used in combination with one or more sample-maps in [[guru-sampler|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//.
