I record but logic express dont record signals only a empty track........i can only record midi signals and i can bounce. But i want to record in the same Time if i play with a VST Plugin I hope somebody can understand my problem and the broken english Yah bless you Peace Cairan

So, can you hear sound coming out of logic when you play? If not, you should ensure the audio driver is set correctly in your preferences. If you can hear sound coming out of Logic, then the problem is probably somewhere in the signal chain BEFORE the sound get's into Logic. Also, make sure you are recording into an audio track ... :)

It sems to me that your not getting audio from your interface to Logic. Logic will record blank regions when there is'nt any audio at its inputs.
