I have a 3.5mm jack running from computer audio out to 1/4 phono jack into the drum machine, but there's no sound when I record a sample into it. It's a ZoomSampleTrak st-224 if that matters.
How do you set the input volume on the SampleTrak? I mean literally, how-- I don't have one. When you do that, is the gain set pretty "hot?" Can you monitor input signals with headphones? Do you? What are you hearing?
