I recently bought a Alesis Multimix 8. I plug in the mixer into the computer, guitar into line 1 and connect my speaker to main mix out L.

When i play all i hear is a clean guitar signal coming straight to the speakers without going through guitar rig. When i play something guitar rig acts likes its being used. I can record something on the tapedeck and it comes out processed.

Does anyone know what the problem is?
