I'm new to Sonar. This problem seems so simple yet so difficult to find the a viable solution. When the Echo button is on I can hear myself but there is a bit of latency added which sounds like I have a chorus effect on, and I don't want that. When the Echo button is off, I hear no input at all.

When I used ProTools there was a menu option called Low Latency Monitoring which solved this problem. Does anyone know how to solve this with Sonar? Thanks!

You need to reduce the latency (buffers) in your sound card via Preferences > hardware > audio. The input echo just allows you to hear the live input and has nothing to do with the latency.

This depends on your sound card and drivers.
The latency can be reduced (or increased) depending on buffer size, but it can't be eliminated.
If you are hearing chorusing, it is because your sound card IS providing low-latency monitoring (i.e. short circuiting in the hardware and echoing input > output ) and you also have monitoring enabled in SONAR.
 
So, what you need to do is a) reduce the buffers to the minimum value that work, and b) disable direct monitoring in your sound card control panel.

Thanks for your responses! I have seen these solutions in the forums, but they don't quite make sense to me. In Pro Tools it's a single click of a menu item. I didn't have to figure out what the sound card was doing, and I didn't have to adjust any buffer size. Seems like Sonar should have a similar option.
