Logic 7: Enviroment Question, A question about audio objects. Options

[_Alex_]

Okay i have a general question. Im starting a project from scratch (just a empty logic template) and i want to have the ESXP24 play in track 1. So heres my logic. i create a track in my arrange window then go to "environment" to create a "audio object" with intentions of making an object and in the I/O plugin part i want to select mono-> then exsp24 then assign the object to "instrament 1" and in track one select "Instrament 1". Thats was my plan, but when i go to environment to make the audio object, the object is empty and just says "off".That is my main problem. However there is a preexcisting audio object that is "on" but in the I/O plugin part will only let me select imputs 1 or 2. It wont let me choose between mono or stereo and let me choose the ESXP24. Im sorry for brothering you guys i am just trying to understand how logic works better and assumed you guys had a better understanding. I thank you in advance. -Alex
