Messing around with the audio render snippet example in the snippet browser....works fine in the example...but when I bring it into my project...it doesn't render anything but dead space...and then the audio in HISE becomes completely disabled and I have to restart to get it back working....im trying to get it to render a preloaded midi file instead of the one that's created by the example...here's the code ive added in the attempt to make it work....
