loops, which are slightly more damaging. The cancel from

Crow Bites to

Trigger is also much easier to do in HD mode.
Going from that last sentence, I was experimenting with shortcuts for DP moves and found out some interesting info. I've been struggling with trying to master

Crow Bites Drive Cancel to

Trigger, since being able to do it consistently grants a big increase in K's corner damage. I tried out the

shortcut a few times, but I found that while I could do it consistently outside of a combo, I have a tendency to "ride" the gate of my stick when trying to perform it quickly during a combo, so it was coming out as

instead, which would result in a Super Cancel to Heat Drive when I would try to go for

Trigger. I had then switched to doing it as

, because while that technique requires much stricter timing, I found I preferred it since I would avoid accidentally cancelling to a DM.
Then I saw the video on Nico Nico Douga where a player was going through K's entire movelist and struggling with the trials where you have to cancel

Crow Bites to Trigger. In one of the scrolling comments, someone listed the input for the Crow Bites as 626A, or

. I went to try it and found out that it works!. This got me interested in messing around to see how else you could input a DP motion, and the results I found were pretty interesting.
In order for the game's command interpreter to register a DP motion:
1. The first input MUST be

2. The second input can be either

or

3. The third input can be either

or

This makes the total recognizable DP motions as

,

,

and

.
This also explains why

works, as the game reads it as the

input.
With this information, I was finally able to consistently perform this particular Drive Cancel easily in a combo. I even make it a little easier on myself by HOLDING

right before I want to do

Crow Bites, then finishing the motion with

(basically like doing Zaneiken with Andy).
Just wanted to share this info. It should help make these DP cancels a lot easier for everyone.
