What worked for me was changing from the Artnet universes on Chamsys to the local universes. In Chamsys/Setup/View DMX I/O under Visualizer
select Capture (Same PC). Then in Capture for each universe you will see two entries:
Artnet Universe 0, Sub-Net 0, Net 0 (Input 1) and ChamSys MagicQ, MacBook-Pro-4.I U1.
Select the later for each Universe.
You also, have to make sure there are channel assignments in Capture, those will map to Head Numbers in Chamsys.
Then in Chamsys go to Patch Window, select Vis Patch Soft button and choose Capture Patch, you should see your fixtures patched. in MagicQ
