--- Comment #1 from Fabian Maurer dark.shadow4@web.de --- Probably not a bug in wine. Did you make sure that your setup is correct? Check https://wiki.winehq.org/MIDI#Using_MIDI_in_Wine for more details.
Basically, for me midi in wine does never work unless the fluidservice is setup correctly and running in the background.
