I know for some characters you have to press

before inputting the next move... For instance, offline I'll do this combo with Xiangfei:

,

~

Normally, the

can't be canceled into

. But the

allowed it to happen, but the input has to be done at a rapid pace...
For Mature, the

requires some "pseudo-buffering"...

(two hits),

The

allowed me to use her far standing

which is a thrust kick that does 2 hits... From there it's just free rekkas... You can be fancy and add whatever in there, but its just a simple

combo...
There's also dashing max mode combos, where you hit say a standing

, quickly dash and

then do another standing

... This is tricky and takes some time to master depending on the character and how their standing

and/or standing

work...
