LATENCY ISSUES W/SONAR 2 and US-428

[ChipD]

Is it possible to cut a track into Sonar while using an effect (like compression or FX reverb on a vox) without latency problems. It seems like the only way I can cut without latency is to cut dry and use only the 428 monitoring (ie: disable Sonar input monitoring and use 428 input monitoring). Is it possible that better plug-in effects would help or is this too much to expect of the technology at this stage. Any help on this would be appreciated.

Here are my computer specs:
I am running Sonar 2.0 on a Sony Vaio Laptop Pentium III 1000 mhz w/512 ram with Windows XP as the OS. For audio data, I use a separate firewire HD (7200 RPM Seagate Baracuda).
Thanks

i'd advise you to record dry.

i've been told that it's possible to monitor cakewalk tracks with the fx as part of the monitor, but i've never had the desire to do it, because the monitoring in sonar even with a dray track has always been too slow for me.

btw, why do you want to?

i've got the m-audio duo, which is a usb mic-pre. i'm finding that usb just doesn't have the bandwidth. incidently, are you able to record in 24bit with the US-428? because the m-audio duo can not record in 24bit using the usb port.

you are talking about the tascam/frontier designs us-428 right? I have the frontier designs wavecenter/tango d/a/d for my desktop.

Yes. I am talking about the Tascam/Frontier Designs US 428. I actually have recorded some at 24 bit, but I get occassional stutters. I have been trying to figure out why this has been happenning. I considered ACPI and the device sharing of IRQ9, but it doesn't seem like I can do anything to change that. I am also thinking it could be my external firewire drive. At any rate I can't seem to resolve it. I am beginning to think you are right about USB.

Do you know how the Firewire boxes MOTU 828, 896 have done in this area? Is the bandwidth better? Overall more stable?

Thanks,
Chip

Here's how to disable ACPI through Win2k or XP:

I had to do it with my C-Port and Win2k. For my situation, it was the only way to correct the driver problem I was having.

Be careful though ...make sure all of your other system's drivers and hardware are working correctly before you do it.

seanmorse:
i've got no idea why you posted that part about ACPI, but i am so glad you did. since re-installing win2k, i've been wanting to separate the irq's and could not remember how to do it.

edited update: and it worked like a charm too. thanks dude.

chipd:
USB has a physical limitation that makes it hard to record in 24 bit. i imagine some company will find some way to do it anyway but most likely at some cost to sound quality. i did not find this out until after i purchased the duo.

I do have a firewire connection into my laptop, but i'm thinking about getting the VXpocket card instead, and using the m-audio duo as a mic pre.
