Pianoing

Pianoing (ずらし押し)

Explanation

Many special attacks and SA's can be done pressing all three strengths of the button ie: LP, MP, HP.  In addition to this, button presses and releases count as an input for special attack and SAs.  Therefore, by pianoing a special or SA, there are 6 chances where the attack may register.  This is useful particularly in situations where timing is strict such as doing link combos.  An example is when linking Seichusen after a Hayate with Makoto. 

1 button pianoing/double tapping (1ボタンずらし押し)

This technique is useful when you want a specific strength/version of a special or SA.  For example, when doing a reversal fierce Shoryuken you would strum your index and middle finger on the fierce (HP) button.  Because button releases count as an input for specials and SAs the game registers this as 4 inputs for the same command.
