Hi Hector, In Logic 9 you can set independent input and output for the device. However, in Logic 8 you will need to create an aggregate device first: [url]http://support.apple.com/kb/HT1215[/url] Then in Logic select the aggregate device as your device and you should be fine from there. Let me know how you get on. :) Rounik

thank you Rounik it works perfect,by the way ,can i upgrade to logic 9 on line? its hard to get the boxed version un my country thanks again hector

Hey Hector, Unfortunately, you can't download the upgrade from Logic 8 to 9 online. The content would be too large. The entire contents of Logic Studio is aprox. 45GB. Most of this will not take up extra space if you already have the jam packs and EXS24 sampler instruments installed though. This may be the best place to purchase the upgrade in Mexico?
