Hi, Roger from portmedia explains the situation here:
http://lists.create.ucsb.edu/pipermail/media_api/2009-October/000751.html In short, OSX does not come with midi output on all machines by default. You need to install a software synth to use it with CoreMidi. SDL_mixer must be using something else to play midi files. Fluidsynth, and simplesynth would be two free options for software synths on osx. cu, On Fri, Oct 9, 2009 at 1:07 PM, René Dudfield <ren...@gmail.com> wrote: > Hi, > > it seems to be able to list output devices that are plugged in.
