Noob Question on live recording

Abandoned pickup machines…now want to live record, but a bit in the dark. Got a bass part looped on a pedal. Want to sample that and throw it into a sequence live. Thought I did all the steps correctly, but…
Any tips?

If you’re still getting silence you need to go back a few steps. Don’t worry about making something musical just get something into a recording buffer of an otherwise empty project. If you can see the waveform then you know you’ve sampled. Then go from there in small steps.
