no signals from core_midi on OSX 10.6 Snow Leopard #1

Open ahx opened 14 years ago

since i updated to Snow Leopard, i don't get any MIDI signals when using the core_midi driver. My setup: Ruby -> MIDIPatchBay -> ...

Things work fine when using the dls_synth. This might have to do with some things around CoreMIDI that have changed since Leopard, but I cannot find any documentation about some major changes. I already told Ben about this. He can reproduce the problem. His original tree has the same problem. I am running your ffi version, so maybe you can help me out.

I'm experimenting exactly the same problem. Any advance on this?

I'm trying to use together with http://github.com/gilesbowkett/archaeopteryx

Also looking for a solution to this. I suspect malformed MIDI messages (had similar issues before, CoreMIDI doesn't complain over bad messages, just drops them), but byte dumps of the messages look the same as working C++ implementations... Anyone figure this out?

EDIT : Figured out a fix. It was basically what I figured... MIDIPacketListAdd changed between 10.5 and 10.6 -- just have to check for Snow Leopard and adjust accordingly. Changes for my sloppy ffi version are here.
