Hi there, I'm new to LMMS, and forums in general!
The only instrument plugin I have been using is the SF2 plugin, but I've encountered a very strange issue. Some instruments have this weird, very dragged on echo. This only seems to happen with percussion instruments, and I have tested a couple different soundfonts to see if maybe I had a bad soundfont file. The two soundfonts I have been using are fanmade, one is an Earthbound (SNES) soundfont and one is a Castlevania Circle Of The Moon (GBA) soundfont. Also, I have a linux device that doesn't experience this issue with the same soundfonts loaded.
I'm not sure how important specs are, I'll just post them.

I also have a video I could share if need be showing the issue.
