I really like that flash guiatr tuner. The online java ones are no good but the shareware downloadable ones such as AP Tuner are good. It seems like your guiatr tuner is telling me every string on my guiatr is lower in pitch than it should be. But I have checked against the AP Tuner and some audio generators I have and I think your tuner may be off by about 20 degrees. Will there be future versions of this same program? I'd love to see a version where you could select which note you are aiming for and then the colored circles wouldn't disappear so quickly when the volume fades. Thanks for the only flash tuner I've ever seen.
