Ok,
I am just using the MusicPlayer connected up to the DLSSynth. This
has all worked fine for years. The user tried various files and none
work. They all play fine in Quicktime. If it is any help, the app is
built with REALbasic so it would be carbon. It could be an RB problem
but it just calls through to CoreAudio/CoreMIDI.
I'll probably install 10.6 this weekend so I will be able to reproduce
the problem (or not) so maybe I will get some errors that don't show
up in the console.

I think he's saying that the midi driver probably isn't the problem
since it works in 32 bit mode. But, if you want to keep it in 64 bit
mode using the USB driver would be one method.
What might be helpful is if you could describe how you are playing
the MIDI through the system audio.

Hi Markus,
I'm sorry but I don't quite understand. The users external device
is working properly, it is playing MIDI through the internal
speakers that isn't working. Are you saying that his Roland driver
is causing this?

Hi,
CoreMIDI supports 32 bit drivers, it does so by relaunching the
MIDI server in 32 bit mode. In your case you have a Roland MIDI
driver installed, which is not a 64 bit driver. You can remove
that driver, if you configure your Roland keyboard to be a USB
MIDI compliant device (read the manual for that, it is not
obvious, but possible)

Hello,
My midi player application, Rondo, is apparently not working
properly on 10.6. A new user has just reported that it refuses to
play any sound out through the internal speakers of his brand new
MacBook Pro. Sound through his external keyboard plays fine. He
says the following console message appears on start up:
8/27/09 2:45:47 AM MIDIServer[542] MIDIServer [542]
starting; arch=x86_64
8/27/09 2:45:47 AM MIDIServer[542] PlugIn
RDUSB0005Midi.plugin -- /Library/Audio/MIDI Drivers/ does not
contain a supported architecture.
8/27/09 2:45:47 AM MIDIServer[542] MIDIServer relaunching
because a 32-bit driver was found
8/27/09 2:45:47 AM MIDIServer[542] MIDIServer [542]
starting; arch=i386
however, this looks to my uneducated eye more like his external
device driver is reconfiguring itself to run in 32 bit mode.
I don't have 10.6 yet - will buy it in the next few days -
however does anyone know what may be going on? Just as
importantly can I suggest some way this user may find out if my
app is having problems with some 64 bit vs 32 bit incompatibility
and what he may be able to do about it?
Am I due for a bunch of support problems :-(
