presonus studio 2 6 usb audio interface issues

What does that give you that just running the stereo 1/4' outputs into your existing interface can't give you? You are not going to have a difference in sound quality. I don't understand why you are fixated on USB output for this. I set up several different session type Templates so it is always a simple click to get it going. save this as a template and then simply select it before you start a session. set up your interfaces and I/O structure and set up a studio one session.

I'd get the ones that actually work well together or you are asking for a lot of trouble. USB interfaces and mix and match interfaces and boards are another story. The Firestudio and studio Live series consoles seem to work well together in this fashion. but if you set em all up in I/O you can select in Studio One what gets sent where and how. I use the FST as the master for studio monitors and headphone sends since it is the stay at home unit. it makes twice the Inputs in the I/O but real easy to select the them in Studio One. I set up both mono and stereo inputs so I have a choice and not have to use 2 mono tracks for a stereo input. you need to go into Studio One and set up your I/O for them both to show up in the I/O pull down windows of S1.

the 1602 now shows up in UC under the FST so i see 2 icons.

I simply connect the 1602 to my PC (i have the drivers already loaded). so it comes and goes into my home system when I need more than 16 inputs from the FST. I have all the studio live consoles but I love the 1602.

I use a Firestudio Tube as my main interface at home. if you are using Studio One you can do this real easy with the Firestudio line of interfaces and mixers. but you need the right type of interfaces to pull this off.
