The guitarist demoing the app is not playing anything virtuosic (thus indicating how robust the tracking is) but I'm sure it will be useful to somebody:

I did something very much like this using comb filters in ChucK. You can search this forum or the ChucK forum for "Guitar Zero" to get the source code. It's tricky but with a bunch of software comb filters it's quite doable.

I wonder if the author of this app is aware of your work, Les.

I dunno, Gov, but it looks like he's got it figured out for sure! It would be cool to learn if he used my work as a starting point or if it influenced or helped him in any way. I wouldn't muscle in on his patent if so.

I contacted the guy, he responded. Really nice fellow, wants to stay in touch. I told him about the pickup system and said I'd dig up my old source code for the chord detection. Coolness, another contact out there!
