I am able to see and hear my guitar input signal on an armed track. I add guitar rig to the effects and drag an amp in. No effects in the sound. The led at the top of guitar rig shows no indication of input signal. How do I get my input through guitar rig so I can try this amp simulator out?

Try making sure that the INPUT ECHO is engaged on the audio track.

yep..input echo,its that blue button right next to the record button.
it turns the sound on/off to the tracks.

Thanks guys that did the trick. However I have new issues. Huge latency from the time I play the guitar to when it is heard. Also, I am using the presonus 44vsl and I only hear the dry sound from my headphones. Takers? Thanks, I'm an old user who got out a while back but am just now trying to get back in the game.
