Moderator advises "No." The Fix is as bolded above and must be performed on a per-patch basis. This problem is actually a "feature" says the mod... Prior to 5.81, Kontakt was simply not working properly with instruments set up to respond to multiple MIDI channels.Ever since updating to Kontakt 5.8.1, I've noticed certain factory instruments - all of them percussion - will receive from all MIDI channels when you first add them to the sampler, much as though they were set to receive from MIDI omni instead of a specific channel... I've been using these instruments for many years and they've never behaved this way by default. Right after updating, I loaded a bunch of the working files for my current project and noticed they were all playing tons of random percussion notes - this turned out to be the cause.
All the offending instruments show their input MIDI channels in the instruments pane as "1 + Groups", "2 + Groups" etc.
I found I can work around the issue by going to the Group Editor -> Edit All Groups -> and then changing the MIDI port in the Source section from "omni" to "MIDI: default".
I'd rather not go back through dozens of my old projects to make this change on every instrument that presents this problem, and it seems like a strange step to have to take in order to have these instruments behave as they used to. Has anyone found a simpler workaround?
Whatever.
