This is actually two modules, but I would suggest looking into Mannequins Just Friends controlled by Teletype: 6 voice polyphony with 2-op FM for each voice and LPG simulation, which means the sounds ring out in a nice acoustic manner. Playing with the Ramp and Curve knobs can result in sounds ranging from strings to horns, especially with some added reverb for more faux-acoustic goodness.

I know this is probably not what you're after and Just Friends can be hard to come by, but I've had some beautiful string and horn type sounds recorded this way, with 6 voice true polyphony.
