William McPherson 7c8bbea995 Piano: Add piano roll ... m_roll_notes[] is an array of 2 bools, pressed and playing. A roll note is highlighted if it is pressed or in the currently playing column, but the note is only actually played if the roll note is both pressed and playing. We change columns every m_tick which is currently 10 frames. The delay is synchronised with this. change_roll_column() tracks the previous column and current column to be played. Each roll note in the previous column is set to "not playing" and the underlying audio note is turned off if it was pressed. For the current column, each roll note is set to playing and the underlying audio note is turned on if pressed.		2019-12-23 15:08:15 +01:00
