CRAFTBOOK-3249 - Reported by Pri

When trying to play a midi file from the folder it doesn't play giving generic instrument errors in the console like below:

{{[15:15:17] [Java Sound Sequencer/WARN]: Exception in thread "Java Sound Sequencer"

I believe the error may be due to Mojang changing the names of sounds in 1.9 or something? I don't know. But it doesn't work under Spigot version 1.11-R0.1-SNAPSHOT F950f8e-655d840 which is 4 versions behind as of this post (updated a few days ago).

I'm also testing with the latest stable craftbook from the spigot page, version number 3.9u12

try builds from ci.md-5.net

Thank you wizjany, I tried the latest development build as instructed and it works perfectly now.

That's been changed for a very long time, CraftBook 3.9u12 is only a few builds old. You must've been using a much older version.

I honestly downloaded the one on the main page here: https://www.spigotmc.org/resources/craftbook.2083/

I shutdown the server entirely, put the plugin file in, verified it was the only one in there, and it doesn't work. I even re-downloaded it just now and it broke again straight away. But the latest one from the dev build page, works fine.. very odd?
