Hello Danny. With the track armed, signal is being received on the track meter. I have variously turned the echo button on and off to see if it makes a difference - it doesn't! Yes, I agree it is a routing issue but I can't figure it out.

I can't think of anything else except that maybe you need a midi track in order to set up recording. If your sound card is good and you have signal and your output with playback is good you should be able to record.

Thank you for your help, Danny. I have tried the midi track option as well with no success. All the settings indicate that it should record but, obviously, I am doing something wrong. I will persevere and see what happens. Do you use the mixcontrol software with your Saffire Pro?  

Not really. Just mixing already recorded tracks.

Sure. The strange thing for me is this. When I create midi tracks, they record without a problem. The audio of the midi tracks comes from an old Sound Canvas module and is fed back into Sonar via my audio interface. When I create a new audio track, I am able to record the output of the Sound Canvas without a problem.
