Anyone out there using MIDI bass guitar to control their synthesizers? Could you share your experiences? What bass/pickup/controller are you using?

I'm currently using my Fender Standard Jazz with a Roland GK2B pickup plugged into a Axon AX-100SB which works pretty well. Tracking is pretty good, though it is a challenge to keep low notes sustaining and tracking on the right note. You have to adapt your playing style. There are many things you can play on MIDI bass that are nearly impossible with keyboard or even MIDI guitar!

Has anyone played a Peavey Cyberbass/MIDIbass? I wonder how they compare?
