Playing All Guitar Notes With a MIDI File

Question

I'm trying to do this:
1. I open FL Studio to play all 88 keys of a piano.
2. FL Studio's Piano Roll begins with C0 which is two octave below C1 of a real piano.
3. So you have to go from C2 up to C9 in order to cover all white and black keys. Like so:

When I save this pattern as a MIDI file and take to Guitar Pro 7, It becomes kind of chromatic and doesn't seem the way I think. I say, if I'm playing all the notes, It should play all 12 notes of sixth string and then next string and then the next. but, instead, It plays 4 frets of 6th string, 4 frets of 5th, 4 fret of 4th, 3 frets of 3rd! and so on. Why this happens. Hope I'm clear.

Answer 1

This is the normal situation on a guitar tuned to Standard Tuning (EADGBe). The A string is tuned one fourth above the E string. And this interval is just 4 semitones or frets away.

Going from the G string to the B string there are only 3 semitones in the middle. This is because B is a Major third above G. It is a little weird and guitar players all have to get used to it at some point (or tune differently).

So, except for the extreme bottom and top of the range, there are usually several string+fret combinations which will produce the same note. And to play a chromatic scale, you could do it in several different ways

$6.0 1 2 3 4  $5.0 1 2 3 4  $4.0 1 2 3 4 $3.0 1 2 3  $2.0 1 2 3 4  $1.0 1 2 3 4 5 6 7 8 9 10 11 12

$6.0 1 2 3 4 5 6 7 8 9  $4.0 1 2 3 4 5 6 7 8  $2.0 1 2 3 4 5 6 7 8 9  $1.5 6 7 8 9 10 11 12

$6.0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23  $1.0 1 2 3 4 5 6 7 8 9 10 11 12

And one more, which probably how I would choose to do it if I wanted the visual effect of moving all the way across the fretboard:

$6.0 1 2 3 4  $5.0  $6.6 7 8 9  $4.0  $5.6 7 8 9  $3.0  $5.11 12 13 14  $4.10 11 12 13  $3.9 10 11 12  $2.9 10 11 12 13 14 15 16 17
