Maybe try replacing the K00 with E00 followed by an H command? Or maybe since you are running the patch on manual, pop an F command right before the K - play with the F value until you minimize the click? But that will most likely result in another click. Idk. You have a few different options.
I tried both; the F command (F00 through F0F) only increased the volume of the clicks, the E00 + H command did nothing; according to the manual, E commands adjust the release on pulse and noise channels - but on the wave channel, they just adjust the volume in 4 steps, which did not really help. I tried putting E02 at position 9, E01 at A and E00 at B, which does seem to soften the clicks, but only by so much that I might just be imagining it.
The detailed description is appreciated, though!
