The projector does except ArtNet (DMX over Ethernet).
DMX controlling tables
Maybe this would be the more common way to do it.
There are ArtNet Plugin Actors for Isadora, but I did not use them yet, as I found them to be a bit unintuitive.
Instead I use QLC+, a free ArtNet/DMX Software, which in turn can be controlled by OSC or Midi.
Instead of moving the lens to a specific position, you could save profiles and recall them. there are specific DMX values to recall a specific profile. (Controlling the motors directly is possible as well, if you switch to the advanced DMX mode).
If you need help with this, send me a message.
