Pretty much what I planned to do so I can take them downstairs and chill out with them but I would need a tiny mixer of some sort I guess (MD+A4).
I take it that you have the A4 running into the OT?
The original post was meant for just elektron stuff and how you have them displayed/mounted etc but it's nice to see some studio's so the thread is better for it.
This is mine just before I sold the Mopho/ESX/2nd monitor and bought the A4 which now is displayed right behind the chair.
