Korg Mono/Poly

I am sooo green with this Korg poly/mono....i just joined a band and 
the bass player has one of these from the 70's...he found in a 
landfill....imagine someone threw this away?
anyway....the sound it was set to was just white noise....i fiddle 
around with EVERYTHING and managed to get a high pitched semi-keyboard 
sound out of it.....i would love to get a string sound then tweak it 
from there.....any tips for someone who has never used  a synthesizer?
i do have the manual but WOW!!!!! i think i need to purchase a 
dictionary to go along with it.......
