“Gertjan” at the WindWorks Design blog posted some interesting comments about using a wind controller in a local production of Seussical the Musical. Gertjan (I wasn’t able to positively identify him from the WindWorks website, but maybe he will find his way here and let us know who he is) played saxophones in the show as well, and used the wind controller to cover a number of wind and non-wind instrument parts.
Although it gives me a little indigestion to see a wind controller substituting for woodwinds that might otherwise have been played by a doubler, I do think there is application for wind controllers in orchestra pits. Keyboard-driven synthesizers are ubiquitous in recent shows (or are sometimes used to replace other instruments, especially a string section), and, in some cases, a wind synth might be even better suited to certain kinds of synthesizer parts. Gertjan mentions some synthy sounds like “vocal doo,” “scary voices,” and “ghostly shimmering breathy sound,” all of which strike me as likely to be very effective with a wind synthesizer’s breath control. Some others, like “harp” and “tinkle bell” seem like they might be more intuitively assigned to a keyboard.
