I bought a used RD-8 MKI and if I make a pattern with and the open hi hat is being used it will play through fine for a minute or so and then the hi hat will drop out of the pattern. You can’t even manually trigger it after it happens. If I turn off and on it comes back but will drop out again. I did try factory reset which I thought fixed it as it stopped doing that. I just went to use it again and am having the same problem. I’m not sure where to get the drivers to try to update but their website seemed to not have any. Any thoughts?
