Hi SX700AusieGuy,
Please press [Direct Access] > [Sync Start] to call up the Split Point display. So that all three Right parts can be played simultaneously, the Right3 split point must be set exactly one semitone higher than the Left split point. The default Split Point setting is as follows:
Style: F#2
Left: F#2
Right3: G2
Note that the R3 split point is only active when the R3 part is turned on.
To understand the "problem" you described, please try the following: First set the split points to the default values mentioned above, then the Chord detection area and the Left area go up to F#2, and from G3 onwards R1+R2+R3 will sound (when all three Right parts are on).
Now, as a test, set the R3 split point to
G#2, i.e. a semitone higher than before. If all three Right parts are now on, R1+R2 only sound on note G2 (i.e. in the "area" between Left and R3 split point), and from G#3 only the R3 part can be heard. Now set the R3 split point back to G3 and the "problem" is fixed.
Important: Then
close the Split Point display (by pressing Exit button or touching the X icon) to automatically save the settings in System Setup.
Note that the current split points are always automatically memorized in Registrations (Style & Left split points with the STYLE checkbox, R3 split point with the VOICE checkbox).
If you want to avoid having your split points changed by Registrations containing different split point settings, you can, as Fred mentioned, lock the split points in the "Parameter Lock" display. Then the split points can only be changed manually, i.e. directly in the Split Point display.
Best regards,
Chris
