I like it as is, but I feel it could be a little better, so I'll do some=20 testing. Being able to examine the note in more detail is one of the=20 aims of the more expensive tuners, so one can check/adjust an=20 instruments intonation. After all, the harmonics are what gives each=20 instrument it's distinct sound. However, I was thinking in it's present form it makes a nice simple=20 beginners project (just ported to PIC) so not sure how much I would want=20 to complicate things. Mind you, adding a few extra LEDs or whatever is=20 not a big deal. Time allowing, I'll see what I come up with.. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
