In Komplete Kontrol, you can filter on Sound Type (Bass, Bowed Strings… ). It also haas a Character column where you can filter on attributes of the sound like Bright, Dirty, etc.
Absynth 6 has a Type column in the preset list, but it seems to include both Sound Types AND characters - it's a mess. Komplete Kontrol has it right and Absynth 6 needs to be fixed to be more like Komplete Kontrol (and Kontakt 8).
In Abssynth 6, I can select a Sound type from the left column. But there is no qay to select a character. You can't use the Search space to filter by character. I think Absynth should look more like Komplete Kontrol for browsing showing all of the Sound Types and Characters that have been tagged with each preset.
