Roland GR-20 synth - experiences ?

[BigBeatNut]

I'm considering buying a Roland GR-20 synth, combined with a Yamaha BB-604 bass (I think) already fitted with a GK-3B pickup.

I've tried this combo in the shop and it seems fine.

It surprised me that there were no tracking issues. Single notes and fifths worked fine as did major triads, though minor triads got a bit iffy (lowest note was pitched a fret too high).

Also didn't notice any latency which was where I expected it might really fall down. Has to be said though, I was not playing along with any other instruments.

Seems that the unit both has plenty of sounds of its own, and will let me drive other midi units through the midi out.

What are your experiences with the GR-20 and/or GK-3B ?
