Had something weird happen to me at rehearsal playing the XK-5 tonight. If I swiped up from the bottom and hit the black preset keys by mistake, the organ would start making a rumbling sound, and the only way to get rid of it was to power off and on. Pressing the C preset did not work. The organ sound was there, but a constant rumbling was there even when no keys were being played.
I made it happen again after a few tries. The Top and Bottom preset button were on, so the black keys had the favorites loaded starting at Jimmy (00) and going up from there.
Most will be asking why I'm swiping the presets? Because I'm not used to playing the XK-5, mine is an XK-2, so it seems I just reached down that low not thinking. And why am I swiping from the very bottom? Because it's not a left hand jazz bass song but rock, a Three Dog Night tune called Eli's Coming.
I'll have to get used to not swiping starting at the very bottom, but it's something I always do on the XK-2. Just be aware that if your XK-5 starts rumbling, it means you swiped the presets. This is the single manual version, no bottom.
