Yes. Safe to run through your bass amp.
When I'm using mine, I take the lead from the pedalboard (which would normally go to the bass amp) & plug into the audio interface. I create a channel in Logic for the bass (you can do this in Ableton) & however many VST channels I want for synths, etc. I then take a cable from the output on the audio interface straight to the bass amp & another can go to the PA (mind make your DAW output mono).
Oh, & 24k Magic is fun to play on the bass guitar too, just tune the bass to Eb.
