Has anyone actually used this with an XK-3C as a controller? I see they mention the XK series as being compatible but I am still interested in any real experience - good or bad. Thanks.
Not yet. I was using my XK1c, which seems to have a different MIDI implementation than the XK3/XK3c since it worked automatically with B5 except having to reverse the MIDI for the drawbars.
I really like the sound of the B5. Lots of editing features, too. But out of the box it has a nice, wooly, gritty sound with good, thunk-y percussion. I'm going to dig more into it and make some demos.
