Hi,
I develop a midi controlled VST audioprocessor, still having two
problems with OS X:
1} Starting up the app, I try to create midi client. Looking at TOP in
terminal, it starts midiServer immediately, which runs at 0% of CPU
load. Then the system passes a timeout blocking my application, with
result Cannot create MIDI client, the debugger assertion reads CoreMIDI:
timeout waiting for MIDIServer to start.
When I try to create client again, the error appears again at once -
without timeout. If i quit and run application again, the midi server is
still running since previous session, and the midiClient is created
correctly.
2}Using MAudio Audiophile 2496 cards, I had set buffer size to some
value, let's say 128. My application asks via
AudioDeviceGetProperty(device, 0, true, kAudioDevicePropertyBufferSize,
&count, &bufferSize); which reports 4096. Changing the value in control
panel of Audiophile has no influence for the value. I also tried to
debug Daisy example, it reports the 4096 just as my application and the
value cannot be changed.
Any idea?
Best regards
