you have the opportunity to expand. You get to choose 1- a fiddle player 2-a horn player 3-keyboardist/ synth/ organ 4-other And why. I generally 'get what's available' But if I had the option, I'm actually not shure what would best fill in the mix. Ask me 12 yrs ago, I'd say horn, 'cos th music I grew up with featured allot a horn. Fiddle is always an absolute kick. Shoulda learned it myself. But for versatility sake, I think I'd lean keys. I've mimicked a lotta other instruments on synth. You can't fake a horn, thou...timbre is just not there..
