Ableton 11 trouble – Syntakt

Hi there,
I try to explain this in english.
I want to use my Syntakt and other Synths (with the Keystep Pro the others) in Ableton 11 Standart.
I dont exactly how to configure the Syntakt unfortunately. I want everything on channel 10 so far. Then make scenes in Ableton on a single ‘rack’. Should be possible?
When I mske a scene yet, everything is going to play, the Keystep and the Syntakt. Cannot seperate them. The Keystep is on Channel 4, but it doesnt show me anything on a channel from Syntakt. I know a few guys had that problem but I cannot figure it out.
