I am writing this message again because I did not seem to get any
response the first time and I think this is a very important issue for
MIDI applications. In 10.2 it was possible to set up devices like the
sound canvas using Audio Midi Setup (AMS) so that a program could
detect which channels were in use for input and output. Now, in
Panther, it is impossible. This makes absolutely no sense (at least
from where I am sitting). If I have a device like a MIDI controller
which does not receive any channels (but sends some) and a device like
a sound canvas which receives many (32) channels, my application
essentially has 2 options both undesirable.
1. Operate under 10.2 principals where I assume the user can set the
MIDI channels for an interface. This results in the sound canvas not
being seen at all because, all MIDI interface devices return an error
when inquiring about kMIDIPropertyReceiveChannels. This obviously is
unacceptable to users.
2. Assume that if an error occurs when inquiring
kMIDIPropertyReceiveChannels that it means that the device receive all
channels. This has a very undesirable affect of having the MIDI
controller keyboard say it is able to receive on all channels.
Can we have a fix for this? Or at least tell me a way to work around
this problem!
Thanks,
Jeremy
