The main thing to remember about playing bass is less is best. A simple bass part played in time goes way further than a busy bass line not quite in time.
Even though I have many years live experience playing a real bass I often prefer to use midi for some songs because I can then fine tune the part. Not that my playing is out, but for simple bass parts it's just as easy for me to play it on the keyboard because for more than 10 years that was the only option I had for live performance. So I got better at it. You will to. That's one of the best things about this hobby, you get to play everything, good or bad. But if you keep at it all will get better. I have become not bad on a keyboard even though it's not an instrument I'd ever play in a band. But I had to get better if I was to use midi.
