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…)
