It’s not confined to just those two algorithms I mentioned. Those are the only two where crossfade is adjustable. I don’t have a solid list of which delays ‘pitchbend’ and which ones crossfade. I want to say it’s about half & half.
It’s easy enough to test out: pick an algo, play a note, spin the delay time parameter. For example, I believe all of the PitchFactor algorithms with delay capabilities, crossfade. Many of the TimeFactor ones ‘bend’. The newer ones … a mixture of each type.
