Help – Geo Synthesizer Review

So I'm not sure why I can't figure this out. I'm trying to achieve two sounds One: A simple bass guitar sound. Two: A electric guitar sound. Also is there a way to record on geo? Aside from that this app is awesome once I figure out these 3 things I'm sure I will come back and give it 5 stars. :)
