Ned has owned a K5 for awhile now, and it’s had a problem with the patch selection buttons not wanting to be pressed. If you press really hard and rock them back and forth, perhaps you can get “2” selected.
We posted a video that demonstrates a fix we applied to our K5 that seems to be working just fine. Take a look and let us know. There’s got to be a better solution, but mine worked. So far. 🙂
