Hello people!
I need help, it's for a competition with a prize at the end, but I don't even know where to start!

The main idea is that I want to be able to literally type on the computer with my guitar.
The more in depth explanation of that is that I want to somehow make my computer anylyse the sound my guitar makes,
and for every specific range of frequency (for every tone) to input a letter or any key on the computer.
Please help me cause I really want to win that competition, so I am gonna try hard to put that system together!

What programming language are you familiar with? You basically need to identify the current major tone, and then translate that to keyboard input.

You won't find ready solution (after all, the competition you're entering into is not for Googling, I suppose). But Google could be your friend to gather the pieces for solution based on Hardware "keyboard emulator"
Have a look at this http://mitchtech.net/arduino-usb-hid-keyboard/. It uses a (very user-friendly) microcontroller connected to your PC, and the software inside that controller emulates a keyboard. Now, find another piece of software for Arduino which listens to analog input (where you connect a microphone, or guitar pick-up), analyzes the frequency, and translates it into a key.

Good luck hacking!

Thanks a lot!
I really appreciate it.
It might be what I go for and I know other recommend me the same. Might be.

However.
You might have heard about the rocksmith and rocksmith 2014 games.
I was thinking to utilized the jack to USB cable they have already made and which works great.

So right now I am trying to get a hold of their developer team to implement what this thread is about, as a guitarcade game as they are called at least in rocksmith 2014.

I am not so sure about the success of that, but if not then I will still like to utilize the existing USB cable and will then 'just' need software on e.g. PC that detects this input and transform them to keyboard keys.

I might be able to on freelancer or similar or maybe a local university here, but more help will also be very appreciated.
