With version 22.214.171.124 of grandMA3 it was possible to control the dual encoder with ShowCockpit via OSC. For Version 126.96.36.199 something changed. I found nothing in the recent release notes. The following OSC functions had to be removed (found in ShowCockpit release notes):
- MA3: update compatibility with v188.8.131.52 - functions "Hardkey", "Encoder Wheel", "GrandMaster Encoder" and "GrandMaster Fader" removed.
Unfortunately there is no longer an ergonomic way to control the dual encoders.
