It depends on what you would like to do with promidi. Generally the examples should give you a first idea on what to do.

OK...  

MIDI will not do anything for guitar.  MIDI is a digital signal that is used to transmit musical INFORMATION.  Such as note-on, note-off, note pitch, etc.  

Instruments that can send or recieve MIDI have special connectors, circular, about 1.5 cm wide, with 5 pins.

A guitar only sends an analog audio signal.  So if you want to analyze a guitar's audio, you should use ESS library.
The ESS library allows you to see the digitized audio signal flowing into your sound card.

Now, go read up on this stuff!  Especially look at the ESS examples.

Maybe he has a midi guitar? Wink

Neo_proc: If not, you should first detect pitch info from the guitar, and convert that to midi. The results you may get depend a lot on the music material, things can get funny if you have lots of overtones, or play complicated chords...In the open source world you could try with pure data or ESS+Promidi for pitch detection-midi conversion. Maybe there's a simpler way, but I'm not aware of it.
