Someone who played in our ceilidh band had a wind synth, which will do what you want. Think of it as an electric clarinet, with thumb switches to select octave, change key, and make individual notes sharp or flat. The processor has switches that let you select flute, clarinet, bassoon, highland pipes and a bunch of other stuff that never went near arundo donax :-)
It should be no great deal to develop an NSP voice for this, but the instrument's real strength lies in doing novel stuff - such as accompanying a flautist first time through as a sax, the second time through as an electric bassoon, and finishing off with a 5-octave arpeggio.
