interesting idea
-
could be very interesting if he can get it into pedal form
-
I've left him some encouraging comments! Would be revolutionary..

Brilliant.
You could also use this to line your guitar into, have an auto-pitchshift using the same software line out to rest of your rig and sound in tune all the time.
I really want to know the gritty details of how he seperated the overtones from the roots of the same pitch on different strings. Best I can think is it assumes that the fundamental of each string will always be louder than any overtone of the same pitch on any other string, and that the overtones have a predictable amplitude ratio to their fundamental so you can figure out what overtones belong to what fundamentals. Clever fella anyway, and its damned good work; however he did it, thats not an easy problem!

Interesting.
How do they solve the issue on those robot guitars?
-
Piezos on each string, I imagine.

I'm not sure how that would work? You mean like, you get the software to calibrate to your "out of tune" strings, then apply correct amount of pitch shifting to each string when you play? That would only work if each string had different output (like piezo?) wouldn't it, unless this guy's "string separation" coding can be applied to other chords and such, but I'm guessing that would be too complex.
Another interesting tuning/pitchshifting gear is called Morpheus Droptune. It can track chords as well as single notes. Sounds pretty accurate. Reviews normally say they are ok for cleans but really excels in high gain.

Yes. And it would work, but on reflection only on chords and single notes. It would auto-tune vibrato and bends out - you'd just hear the root note!

Seems TC Electronic are already coming out with this in Hardware:

The problem I see with this is that you'd have to tell it what tuning you were meant to be in before using it - not a catastrophe but for a lot of players it might detract from the speed of tuning. Working out which string is out of tune doesn't really take that long with a conventional tuner anyway - somewhere in the region of 6 seconds...
Interesting idea, but I don't really see it being better than a decent pedal or rack tuner for ease and speed of use.

I agree actually - it is overall a fix for a problem that doesnt exist.
Most relatively experienced guitarists can tell which string/s out of tune when they strum a chord anyway, and its not hard to find it otherwise.
I'm just impressed with the ingenuity of the analysis and decoding of the waveforms he must have put into the software. I work with moderately closely related things (or some of my work involves moderately closely related things) and its not a simple task - really quite impressive that he figured it out and got it working. Most people, even competent scientists and engineers, would have written the job of seperating fundamentals and harmonics of the same pitch from a second source off as impossible or too hard to be practicable.

I think it's a great tool - seeing the finished article being used it seems really good.
Great for when you are in a noisy environment and need a quick check.
It can be programmed for dropped tuning too

But it cant do Drop D or other alternative tunings only standard down up to 5 steps. Which is a deal breaker for me as I mostly use drop tunings.
Great idea though
