For the smooth/pretty sound, I stuck with the analog mode of the synthesizer. I kept the low pass filter at 12db, moved completely to the left, but I didn't  include noise in osc 1, which I changed to be a square wave. I also kept the mixer completely on osc 2 in order to reduce noise. I increased the amplification wave time, making the sound softer, and changed the filter wave and the volume in order to make the sound less punchy.
