Guitar Chord Arpeggios - Confused.

Background:

Hi there, I am currently notating some songs from sheet music on Sibelius so I could export them to midi, then import the completed midis to a sequencer where I assign sample-based instruments to each instrument sequence.

Problem:

Unfortunately, it has not been enjoyable dealing with the not-so-intuitive manner in which the guitar is notated using slash chord symbols above the staff as opposed to your standard notes.

I figured out chord symbols but the score calls for many of them to be arpeggiated. I thought that meant individual chord notes played in sequential order up or down, depending on what is called for. But my work sounds nothing like what it is supposed to. In some songs, the entire guitar notation is all slash chord symbols with rhythm bars and some even instruct to play "low inversion arps"--so confused.

Conclusion:

I'm having trouble figuring out how to notate guitar slash chords and "low inversion arps" and translate all the fancy guitar vocabulary into standard notation. Chord arps are even more confusing as I don't know exactly how much space in between each note of a chord or how they're supposed to be arpeggiated exactly. The goal is to get each guitar strum notated so it can them be exported into a midi sequence that, when played back, replicates the guitar section of a song exactly as intended.

For example, how would one translate the following, which appears above a standard notation; 4:4 time; one flat key signature staff of 4 measures (tempo @ 80):

Instructions: Low Inversion Arps

Bb Ebm/Bb | Bb Bb/A | Gm Bb/F | Eb |

Or the same as above but not in Low Inversion Arps, but just regular Arps?

Any help would be much appreciated. Thanks for your time.
