I had a situation today where we were trying to bounce down about 20 tracks of various softsynths, including EXS24s , Stylus, and sculpture. No recorded audio tracks. The producer asked us to provide 24bit/96Khz files for importing into Pro Tools. We failed because every time we tried we got system overloads "system overload. The audio engine was not able to process all required data in time." (-10011) . Even with all tracks muted except the one sound we were trying to bounce. Even trying to bounce the klopgeist click failed. Also tried recording the sound via a bus to an audio track failed. We went back to doing it at 44.1 and that succeeded, forcing us to ask the producer to make the sample rate conversion on his end. While watching the 4 processors with "system usage" meter- I noticed severe "spiking" on a couple of the processors.(MacPro 2.66x4 with buffer set to 512 in Logic. MOTU 828). Is it that these synths don't like 96K? Other culprits? HELP!!!
