64bit on the MAC or on Windows ? I tried the EXTERNAL knob it works with that weird editor from MOOG, the Octave switches are on the panel for each oscillator i don’t understand what do you mean that it’s missing. The main volume knob is in the Performance Controls. I’ll add a program/bank change but can you tell me how many banks and programs per bank the Voyager has ?
I did a small update of the panel with some minor tweaks, so re-download it.
