What is stack mode?

(some parts from another brochure)
By utilizing MAX(4)'s Stacking facilities 2 extra variations of a sound can be tuned and stacked on top of the original sound to make more authentic organ, 12-string guitar, chimes and many other unique effects easy to achieve.

*82**	8 note X 2 voice:	the sound of the extra voice A is on
*44**	4 note X 4 voice:	the sound of the extra voices A, B and C are on

STACK MODE COARSE TUNING

STACK MODE FINE TUNING

Number after the dot: set the fine tuning of voice A, B or C (0 to 99 of a semitone)

From yamahaforums:
"If your DX7 has SuperMax extension you should consider yourself lucky. In fact there are two extensions DX-MAX and SuperMAX. First one will give you more voice memory and voice stacking, the second one will give much more."
