I have a lot of the same questions and issues as you are facing. I use 3 screens. I have a 24" touch that I can pull in front and adjacent to me that I use for a console view. I have recently started playing with Studio One remote after a discussion on the old forum. The launcher section, unfortunately, is limited to the same capabilities as S1 itself (duh!) with no provision for triggering either cells or playlists. In a perfect world, something as simple as a touchscreen (or a tablet) could trigger cells subject to a user's input quantize settings. I'd love to see someone using a launchpad (or an Atom/Atom SQ) triggering and "playing" cells in the launcher Ableton style. The launchpad is apparently "supported" now in S1 7, but I don't know what that means/looks like. I tend to be more early adopter than bleeding edge leader. Show me, dammit (lol

) (I really love this forum, BTW - thank you Lukas)
I sent an email off to Novation this afternoon asking for some advice about the Launchpad and SO1 7 ClipLauncher, should they get back to me I will let you know.
The Atoms from what I know have a scripted/Midi Device which presonus have written and once switched to ClipLaunch mode that script kicks in.
As always I am not 100% about this, as I am working upon assumptions from other Daws and hardware sequencers I have and use.
The Novation gear may be playing catch up with the release of SO 7, so I would either ask them, like I have.
Or just sit back and I can get back to you on here.
That being said others asking might get Novation working a bit harder

and also, you might have diffrent idea's/needs on how you might want to do things.
I couldn't see anything on the Novation website, so it might be better to wait before buying a Novation Launchpad!!!
In the meantime the Presonus stuff should be working if you want to take the plunge.
Oh! Novation just got back to me and the newer models have been given control of the Clip Launcher by Presonus, it's in the SO1 7 release notes
Under the heading...
General.
From what I can see the the SO1 C/Launcher needs to grow and get some functions for Launch states to be developed/implemented.
This topic might need breaking out into Clip Launch thread, rather than hijack this one...
Regards as always.
