The order of variants in the config file will never change, it can only get appended.
This way indexing will remain consistent over time.
NOTE CONCERNING THE BELOW:
The instruments are not really described by semantic versioning. That was the initial plan
but it showed that versioning of third party instruments is difficult or impossible.
But it also is not needed nor practical. New versions are so rare that one can easily
find individual schemes to name and differentiate variants.
The default variant after the first start (no save file) is the a special entry in metadata.
It can change with new versions, so new projects will start with the newer file.
Examples:
SalamanderPiano1.2.sfz
SalamanderPiano1.3.sfz
SalamanderPiano1.6.sfz
Here we have versions 1.2, 1.3 and 1.6. 4 and 5 were never released. A dropdown in a GUI
would show these entries.
Patches are differentiated by the MINOR version as int. MINOR versions slightly change the sound.
Typical reasons are retuning, filter changes etc.
The chosen MINOR version stays active until changed by the user. All MINOR versions variant of
an instrument must be available in all future file-releases.
PATCH version levels are just increased, as they are defined to not change the sound outcome.
For example they fix obvious bugs nobody could have wanted, extend the range of an instrument
or introduce new CC controlers for parameters previously not available.
PATCH versions are automatically upgraded. You cannot go back programatically.
The PATCH number is not included in the sfz file name, while major and minor are.
A MAJOR version must be an entirely different file. These are incompatible with older versions.
For example they use a different control scheme (different CC maps)
Besides version there is also the option to just name the sfz file anything you want, as a
special variant.
What constitues as "Instrument Variant" and what as "New Instrument" must be decided on a case
by case basis. For example a different piano than the salamander is surely a new instrument.
But putting a blanket over the strings (prepared piano) to muffle the sound is the same physical
