people who think that the tuning peg things have to be straight. I went to the bathroom once, I come back, and my friend detunified my guitar, and then asked why it sounded weird. ARGG!!!

In the control panel make sure the interface is set as default. Also set the interface as the input and output source.

Make sure you have the latest drivers and that they are compatible with your current operating system.

If on a laptop or using any wireless, disable the connection. Sometimes skipping this step will cause software to crash and lead to hardware errors.
