I have an old Pattern with 4 tracks. 3 of the tracks have a split keyboard (zones), why I don't remember. But I'm not finding how to remove the split & extend the zones within Pattern mode. The voices assigned to the 3 tracks do not have zones assigned and use the entire keyboard. Where does one find zone controls in the Pattern mode?
Technically speaking, “Zones” are only found in Master mode, perhaps you are referring to “Note Limits”
Note Limits set a High and Low Note region for a particular Part
Press [MIXING]
Press [EDIT]
Press the Track [1] button to view Part 1 parameters
Press [F1] VOICE
Press [SF3] LIMIT
Here you can set the Low and High Note Limits for the selected Part.
C-2 is the lowest Note on the ‘mythological’ 128 Note MIDI keyboard
G8 is the highest Note.
Reference points: Using C3 = middle C...
A standard 88 key piano goes from A-1 thru C7
A 76 key instrument goes from E0 thru G6
A 61 key instrument goes from C1 thru C6
