so, i think i'm a little out of date regarding how i'm imagining guitar to midi conversion.

i tried working with an evaluation copy of midi guitar a few years ago and couldn't get it to work right, but there are now several pieces of software that purport to perform this task, and i'm really better off approaching it from that angle. the idea is you convert the note to midi in real time, and it's fine so long as your computer can keep up. reaper seems to do it natively.

that approach should work for bass, too - meaning i won't need a dedicated plugin.

but, i've always wanted to plug directly into the jx, and may consider converting the dx100 into a guitar processor. the best way to do that is not to get a midi guitar but to get a hardware audio to midi interface.

the downside is that it's monophonic, but i can deal with that if i can get the polyphonic version working in software. 

careful - most of the versions have usb outs instead of midi outs, meaning you'd need a separate converter.

i'm going to get a cheap midi to usb instead for maximum flexibility. and, now i can finally plug right into my synths....
