What synth is this?

[Zoola]

My sister loves they might be giants, and I heard this cover of 'puttin on the ritz' they made. Its a neat song, but I can't figure out what the synth is at the beginning is, I know I've heard it before. Any help?

Here's a clip:

sampled monophonic string(s)?

[analoq]

could be a minimoog, but you're probably looking for an interpretation of that patch?

i'd say the main characterizations of that sound are portamento and vibrato.
the waveform sounds like a pulsewave thru a lopass filter.

that's off the top of my head and probably a good place for you to start,
but i'll see if i can make an example for you tomorrow.
cheers.
