I do have a hexaphonic pickup and a roland and axon device for converting guitar signal directly to midi. But I must say there is a big latency coming from the bass strings. The lower the strings, the bigger the delay. The treble strings almost have no delay. This is not very satisfying for recording, becasue the delay alter depending on the strins / notes you play.

But I have another solution for you which works at least for monophic playing very well:

Just record your monophonic guitar playing (single note playing) as an audio track. Then you can convert the audio signal to midi by a "audio convert to midi" plugin. You can listen to the results and change some plugin parameters to get best results without having to play again.

Finally you can edit the midi notes with the midi editor.
