Apple

I have however a new question.

Again, when I connected more midi devices, and called

ret = MIDIClientCreate(cname, NULL, NULL, &mclient);

a second time, I don't see an update of the number of devices when I use.

endpoints = MIDIGetNumberOfSources();

as a result, I'm unable to see the new midi devices plugged in.

However, if I close my app and start again, I'm able to see the new devices.

Has anyone encountered this?

Thanks.

Pier.

In my code, I call

for which the first time is returns ret == 0 , which is ok.

I then call

ret = MIDIClientDispose(data->mclient);

for which mclient is the same mclient instance as the one being created. ret is 0.

I then want to re-detect the midi devices, so I create the client again and subsequently run through the list of midi sources. However, on creating the client again using :

ret = MIDIClientCreate(cname, NULL, NULL, &mclient);

It gives me ret == -50 , which is a (paramErr): error in user parameter list

What is causing this? Help greatly appreciated.

Thanks.
