Kinda new at this - I got a question,

What system or software do I need (GR20?55?...?) to be able to trigger pads/textures/loops (w/controllable tempos) from the lower 2 or 3 strings of my guitar (kinda like one finger accompaniment on cheap keyboards), while soloing on the higher strings?

Thanks

Well if you wanted to trigger auto accompaniment obviously you would need to use a tone module that could do that like the Roland BK7m unless you will be using a computer then you could use auto accompaniment software instead ( see my links at http://www.synthzone.com/midiaccomp.htm for possible software solutions ). Either way you would still need the GR-55 as well to plug the GK-3 pickup into to provide MIDI data. So if you were using a computer then the GR-55 and software would probably work.
