I'm routing a sound into a multi Fx which works fine in maschine however when I drag and drop the sound into logic there is nothing in the sample. Help!

What format is the sound you are trying to drop into Logic? Test if it plays in Quicktime. If it cannot play in Quicktime, then Logic won't recognize it. You may need to change the format of the sound then.

If I don't route the sound through the FX it transfers fine it's as if it's to do with the router setting in some way. All the sounds are Maschine samples.

So the Maschine sample does not have any effects on it, but you are applying the effects with Maschine's multi FX? If so, then you will need to bounce the sample down with the Maschine FX's, then import the new sound file back into Logic.
