Logic Studio apps Mainstage FW Interface Problem

Uwe Rodi

I'm using mainstage with a Macbook (1,1 Core Duo 1.83 Ghz 2GB Ram) and a Focusrite Saffire pro 24 Interface.
It worked fine for me but now from time to time the Audio Output stopps.
I looked in the Console Programm and found the following lines:
11.03.11 14:56:41 kernel ERROR: FireWire (OHCI) Lucent ID 5811 built-in: handleUnrecoverableErrorInt
11.03.11 14:56:41 kernel Saffire: ReadFWBuffers (0): receive mismatch
11.03.11 14:56:41 kernel Saffire: timestamp FIFO (0): using 4458 for packet with DBC error
11.03.11 14:56:41 kernel Saffire: ReadFWBuffers(0) dbc 1, received: 0000, expected: 0040

Does anyone know this problem or has a solution for it? I can bring back the sound when I change the Buffer Settings in Saffire MixControl but no matter which setting I choose, the issue comes back after a while.
It seems that it happens under high load of the processors.

Greetings Uwe

Can't help with your problem but I still get problems with Ultrabeat loops no longer responding after a CPU spike.

Never had an explanation so just try to live with it.
