Z3TA+
Under Oscillators, select the GL tab. You will see Bend Up and Bend Down. Each can be adjusted +/- 12. There are also some very cool bend modes - Low - only lowest note bends on a chord - High - highest note in chord bends, and Hold - only key down notes - not sustained or released notes.
Z3TA+2
Select the Perform tab on the Synth screen. In the upper left corner you will see Bend Up and Bend Down. Each can be adjusted +/- 12.
Bend modes - Low, High, and Hold. Z3TA+2 also includes assignable bend scale and root. Good stuff!!!
