/*
A nearly trivial guitar tuner app, 5/97, by Lisa Gade, made with CodeWarrior 11 on Mac.
Sampled notes from my Martin OMC-28 acoustic (tuned with quartz tuner, A=440),
artsy impressionistic picture of tuner courtesy of moi via Infini 3D and Photoshop.
Feel free to learn from or use pieces of this code. If you use substantial parts
of it, I ask that you give me credit, and perhaps even a ref to this page. Enjoy!
Last updated 7/22/97 to fix font sizing problems on Mac under Communicator 4.01
