I cannot get pitch bend range adjustments to work outside of the Basic set either. Through macros or otherwise.
In HALion version 6.1.15.89, Standalone 2.5.10.35, on Windows 10.
I tried it with a Voltage program (Brite Light) that has unlocked layers.
Changing PB range in the macro does nothing.
Changing PB range in the Zone/PITCH editor does nothing.
