DROPOUT, Wow!

Mixing orchestral sections down to audio from 4 instances of Philharmonik, about 70 tracks. Got everything mixed down to 5 tracks of audio except 4 tracks of midi percussion. When playing it I suddenly get a red DROPOUT bottom of screen and Sonar freezes up. Get into Task Manager and find Sonar using 153,000 memory, Bitbridge using 605, 000 and processor running at 100%. Try and stop Sonar in Task Manager but doesn't work. Have to hard shut-off computer.

Could this be the reason? After mixing to audio I delete the midi tracks. So there are three instances of Philharmonic that don't have associated midi tracks. I can't think of anything else.

This has never happened to me before. Running an i7-950 at 3.09 with 12g memory at 1333. Every so often I get a blue screen of death memory disaster. I think it's my new Gigabyte  board. It won't run the memory at 1600 at all even though the memory cards are rated at that speed. Have a new board on order.

    What's your buffer size? Dropouts shouldn't be an issue with rendered synths. More likely, it's due to heavy-CPU bus effects like Perfect Space. If your buffers were initially set to small values for minimal latency during live recording, they may just be too small now for mixing. You can bump them up as much as you like for mixing.

    If your buffer sizes are already at large values, then something else is going on in your computer that's hogging the CPU or I/O bus and starving the buffers for data. Make sure you don't have anything going on in the background such as antivirus software, and try disabling your network if you have one.


    All else is in doubt, so this is the truth I cling to.

    What's your buffer size?

    Not real clear about buffers. In Audio Advanced they are both 512. In Audio General, Buffers in playback has 2 but looks like that is all greyed out.

    I bounced the rest of the percussion without trying to play anything, deleted all the Philharmonik and am now mixing just in audio and it's working fine. Saved to a different name though so i can try some things with the one that didn't work.

    If all was well after bouncing the samplers, that suggests buffer starvation (could be memory, but you've got 6 gigs and Miroslav is one of the more RAM-efficient samplers around so that wouldn't be my first guess).

    Sounds like you're running ASIO, which is why the buffer size slider is disabled. With ASIO you have to specify buffers in the ASIO control panel, and you have to enter it as samples rather than milliseconds. The 512 you see on the Advanced tab refers to a different set of buffers (disk).  Click on the "ASIO Panel" button to see what your audio buffers are set at.

    Out of curiosity, what synth are you using for the percussion?
