Is the Showcontrol Manual Rev C from 2017 the latest version? This appears to be the only version that is to be found on the ETC website.
If this is the case, there is at least one mistake I guess.
The example command to set OSC to a certain user is set to explicit but does not work.
On p. 59
/eos/user |
number for OSC user ID |
/eos/user=1 /eos/user=-1 /eos/user=0 |
This method does not work.
/eos/user/1
does work.
