Within piano midi how do you play guitar

[EMPORIO]

I'm thinking it's mostly just long and short notation placed within a melody and timing. Can someone help me out.

How exactly do you mean? there are lots of subtle nuances, including sliding, pitch bending, vibrato, velocity differences, strum delay, consideration for the limits of the human hand, etc.

This is true of any live performance recreated using MIDI.

LEGATO!!!!

[Toxikator]

but NOT portamento (which is what the Legato function often does)

[EMPORIO]

what is legato anyway I mean is it like a certain option in a synth or what not can somoene clarify please.

If you're trying to emulate a guitar via MIDI it is important to note when playing a chord that all the notes will not start at the same time. You have to make the trailing strings lag behind the first note by a very small margin. I do this with velocity controller data. Also, the trailing notes are not played at the same volume as the first note.
For leads, alter the velocity so that hammer-on's & pull-offs are softer than the first notes in a phrase.
It's a process of trial & error which depends on what you are trying to do & the sampleset you're using.

it's also a matter of getting the notes realistically spread as if played on guitar
the chord structure of a guitar are very different from standard piano chord structures -- hands don't span like that on a keyboard
Computer Music -- probably a year and a half ago or so had a set of midi files with guitar spread chords and strum (time offset) patterns and I found that very useful and approaching 'real'

Something like this might be appropiate:



Notice 3 things:

1) The chord is written as it could be played on the guitar. - The spread of the notes corresponds to the fingering of a chord which is perfectly possible to play on a guitar.
2) The notes do not start at the same time. - As you get higher, the notes start later. This corresponds to a typical strum of the strings from low to high.
3) The velocity of the notes gets slightly less each time. This again corresponds to a typical strum.

Note also that the reverse of this is also possible; a back strum from high to low would obviously be the opposite.
There is obviously more to it if you really want to create an authentic sound, but this is a good starting point.
