I still use Kontakt because it has many useful features which Sample One XT hasnt. But I really miss the diorect recording features. Missing effects is no problem, but some basic functions which are important for designing instruments and for sound design:
-duplicating and order changing of recorded samples inside Sample One XT
-slicing threshold
-Hold parameter for the volume envelope
-retriggable syncable random modulators S&H, random static value for every trigger and random dynamic modulator
-restart mode for LFO(s) (two modulators would be better)
-different layer trigger modes like within impact xt like round robin, random and together to generate realistic instruments
-settings for pitch, pan and volume for every single layered sample
-a notch filter (resonance is steepness and you can change the notch to a peak filter(bipolar resonance control) and two filters whit parallel option with a crossfade knob
