For my percussive patch, I used the table setting of the retro synth. I found that a high attack with a square wave fit my idea best.

Smooth
For my smooth sound I used the analog setting of the retro synthesizer. I found that a longer decay and slight vibrato gave it the warmer tone that I went with. I also used the triangle wave for my Shape 2 to give it a smoother sound.

Alien
I also used the Analog setting for my alien sound. I cranked up the vibrato and also shifted semitones by 8. Changing the cutoff to 0.03 gave it a more hollow sound. Finally, I also had a long release to give it a more otherworldly sound.
