Possible Easter Egg

[Henry Millbrook]

If you transpose the keyboard's pitch up by by 2 octaves you can trigger any SA voices by pressing the 2 rightmost keys.
I can't find anything in the Data List about it. Anyone any ideas?

If you record a performance of an SA2 voice. those high keys are the articulation notes, to make a change.  It's not so much an easter egg, it is how the instrument was designed, the articulation keys put out those high notes, not normally performed with regular playing
