Optical engineers routinely work with digital micro positioners. One could be attached to your tuning slide and wired to your digital tuner. For even better results, a second contact mic on the principal oboe could be sampled to provide the pitch standard.
Even more fun is to swap two tuning slides on the principal's horn, and see how long it takes him to catch on. _______________________________________________ post: [EMAIL PROTECTED] unsubscribe or set options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
