GHMC operator’s manual

The pictures below show the fingerings for each individual note. The final few photos show how to change the different modes and options that the guitar can operate in. There isnt much to it really, set the key and play the notes in the scale selected based on fingering and strumming. Strumming down makes the notes slightly louder than strumming up.

The fingerings are shown along with the note that will be sent via midi when the key is set to ‘C’. basically it does not operate in a chromatic scale, but rather a standard 8-note scale.

The last few fingerings show the mode select (guitar or drum), chord select (root only, root+fouth, root+third+fifth, powerchord), key select (any note, in the circle of 4ths order starting on C), and tonal mode select(dorian, ionian, mixolydian, etc…)

  1. […] pages the whole project is spread out on – GHMC – program and introduction page GHMC – musician’s user’s guide GHMC – youtube video1, video2, […]

  2. actually the 5th and 6th positions are incorrect –
    5th is the red and yellow buttons together.
    6th is the green and yellow together.

  3. […] the world or do whatever i wanted. Quite a deluxe modding job – featuring a power chord mode and a user’s manual describing note fingerings. Always so nice to see that welcoming 5-pin jack on a piece of gear! […]

  6. Hi really interesting. Only two questions. First, do I need to modify the axe or can I just use the wiichuck adapter? Second, how realistic is the fingering with respect of a real guitar? I mean, is the same I would find in any “learn to play the guitar” book?

    You could certainly use the wii-chuck adapter on todbot’s blog. Or you could use an extension cable and cut that to hardwire it all together. The only reason i cut mine up was to save the adapter and to make sure it didnt fall out of the plug once it was all tucked inside the guitar.

    The fingering is a little off though. i used to play baritone (euphonium) and the fingering is loosely based off of those fingerings. but if you were to make your own, you could modify the fingerings however you choose. in the large Switch-Case section of code in the guitarMode() function you just adjust the cases for each note to be what you’d want the scale to look like. the code is pretty heavily commented, but i can always help if you cant figure out what you’d need to do.
