I can tell you that the tracking depends largely on how well the MIDI pickup is installed and setup. These Roland units always track a little better in the higher register but I found them to be totally usable over the full range of a 5 string bass. I mostly have used it with string and synth patches but I've also done some flute and sax stuff too. It's loads of fun and it really adds some new dimensions to your music when you mix the patches with your normal bass sound.
I bought this unit because I had just purchased a Stambaugh 5 with MIDI capability. Unfortunately when I received the bass the MIDI circuitry didn't work properly so I returned it for a refund. Now I'm stuck with the GR-20 as a result.
If you've never used one of these you really should consider trying one out.
