is there any software or anything that you can connect your guitar up to the pc and what ever you play it tabs for you?

would probaly have to be midi interface or some sh**?

I doubt it based on how fast it'd have to process things based on speeds people play at. It'd also be tough because the same note at the same octave is in many different places on the fretboard, not to mention it needing to pick apart chords. I know there are programs that pick up what you play on a keyboard but I doubt it for guitar, although it'd make things very easy

ive heard of sumthing like that for teh drums but guitar is weird, i think maybe if u had pressure sensors under the frets it might work but that could be iffy.
