Pro Tools HD System can't get audio fast enough?
Hey all I am working on setting up a live recording studio for my church. We just purchased (3) 192's and (1) 96. We are trying to record 48 tracks simultaneously (drums, guitars, keyboards, vocals). I can get it for the first 3 minutes and then that error pops up.
We are recording to our (3) 250GB's Glyph external drives. Using a firewire 800. Does anyone have any idea what the problem is? I gotta get this working. Mac OS X 10.4.11 Dual 2.5 GHz PowerPC G5 5 GB DDR SDRAM Pro Tools HD 3 - 192's 1 - 96 3 - 250 GB Glyph Drives 3 - 1 TB Western Digital External Drives |

You might try zooming way out on the session...so the cursor is just barely creeping along. We found our system worked much better when the graphics aren't bogging things down. When we did that, we never had a problem...but when we zoomed in, we were having problems like yours.

Re: Pro Tools HD System can't get audio fast enough?
need LOTS more info
what version of protools? what sample rate? if the drives are daisy chained, how did you set up disk allocation? How many voices per drive? what is your buffer set to? how many voices/DSP in engine? did you set the max record time preference? how are you clocking your interfaces? once you sort these things out, it may be clearer... and I will guess that it is unlikely related to any video card issue, unless the video card is defective.

Re: Pro Tools HD System can't get audio fast enough?
Try 96 voices (6 DSPs). On slower/older macs, this helps the PCI bus. And that may be related to your issue.
Look in the preferences for "open ended record allocation" and set it to the longest time you would ever record (not open ended). Quote:
how are you clocking your interfaces? -- as in, have you set up the loop sync exactly as specified? On multi-interface rigs, bad sync can beat you up. Try these things -- it may just be a balancing act of resources.

PS -- do you have any accel cards? Is your rig HD or HD2, HD3, any cards accel?

Only 1DSPs 2DSPs and 3 DSPs @ 96 voices. Why 1 processor over 2? Our clocking interface is 96i/o internal clock, 3 192's are looped. Our rig is HD2. Is that the accel card? |

Re: Pro Tools HD System can't get audio fast enough?
On the system at my church I have experienced this with both Glyph FW drives and even internal SATA drives. This has happened more with larger sessions, but still ones that should have been beyond fine. I firmly believe it has something to do with being a PPC processor (it's on a G5) as it has been very random. But when it does occur, it's a freaking nightmare headache!

A nightmare headache ehh? lol
Umm i honestly believe it was just the zoom in and out feature. We will find out tonight. I will keep you all updated. |

Re: Pro Tools HD System can't get audio fast enough?
It's probably irrelevant, but as I recall, it is recommended that if you have a mix of 192s and 96ios that one of the 192s act as the clock source.
