A DAW + Sound Editor problem

[valeto]

Hello!
I have a problem.
I connected my RADIAS via USB to PC.
I can't get my DAW (Studio One) and Sound Editor to work simultaneously.
I mean I assign as it should in the Studio One the ports RADIAS 1 KBD/KNOB and RADIAS 1 SOUND respectively for the midi track.
In Sound Editor I leave the ports at default values and they are the same as above.
As a result, either DAW works or Sound Editor works, but not together.
Did I do anything wrong? OR if all right, is there any workaround?
Sorry for my English.
