You could download the free Kore 2 Player. It will take a
LOOOOONG time to set up all of the sounds, but once you do, you can use Kore 2 Player to search for your presets by instrument category - such as bass, synth, plucked strings, wind instruments, etc... or by Timbre - such as hard, fat, soft, metallic, etc... Or you can search the VST - such as Rapture, Dim Pro etc...
Like i said though, it takes a hell of a long time to set up. I spent literally a whole day going through Cakewalk instruments presets and categorising them inside Kore 2. I have Komplete 7 which came automatically set up for Kore 2.
It's very tedious setting it up as you've got to go through literally thousands of sounds one at a time and then decide which categories to include them in. But it's well worth it as you only have to do it once and it's set up for life. I've slowly been adding 3rd party VSTs over time, so now if i need a specific sound i can search for it inside Kore 2.
