Anyone used a Roland GK-3B pup for anything? I got this setup in a trade for a bass this weekend, haven't had a lot of time to experiment with it yet but so far I've been quite impressed with the tracking. Obviously the latency on low notes is quite poor but I'm happy to play everything up an octave like I do for analogue octavers. Anyone put any time in with Roland's pitch-to-MIDI stuff? Any advice?
