This has been around for a while, so I tested this with the new Reaper 7.07 in almost the newest AVLinux, with a recent wine-staging 8.x

In the photo are two of the stellar windows freeware synths, Superwave P8, and Oatmeal.
Nanohost provides it's own preset handling if a plugin does not have it's own, as is the case with P8
Oatmeal has an excellent built-in randomizer, and provides cheesy names that you can replace as desired.
The Oatmeal skin is one that comes with a common archive of sounds skins and the plugin:
