SAFFIRE PRO 40 AND CUBASE 7

OK, what I want to do is the exact opposite !

I don’t want to hear the direct signal from the Saffire Pro when recording in Cubase…i just want to monitor through Cubase by activating the little “speaker” icon… Is this possible ???

For example, if i want to plug in an electric guitar, then insert an “Amp Sim” on that channel so i have a nice distorted guitar sound while I’m playing and recording it… i don’t want to hear the clean direct sound at the same time…

I used to be able to do this no probs with my old Cubase 5 and the Presonus Firefod interface…

Im currently using a Macbook Pro, with Cubase 7.5 and of course the Focusrite Saffire Pro 40 audio interface…
