any luck at 96Khz?

I've just been playing around at 96Khz and I can't get my system reliable. It's a Pulsar I and PowerPulsar.

I've been avoiding Minimax since it's not 96Khz compatible but as I increase the DSP usage to about 3/4 I start getting DSP error messages.

Anyone getting 96Khz to work?

Anyone think I should give up and stick to 44Khz?

First make sure you're only using the i/o on the Powerpulsar and not the Pulsar1

Yes I've done that, I haven't even got the pulsar i/o's loaded.

I have two Scope cards, and I can't get 96KHz working proberly either...
I get all kinds of error messages like "Not enough audio bandwidth between dsp's" and "Big modules won't fit" !!!
I could live with the fact that some of the synths doesn't work in 96 since I need it mostly for mixing and mastering, but not even the STM-mixers seems to be working.
(On my setup anyway.)

On my system with a Pulsar 2 and an XTC card, there seems not to be any problem with 96KHz (except heavy ASIO load)...
By they way, Kim, I d like to ask you a question: I was always wondering how easy would be for Creamware to make our cards working at 88.2KHz? I think it shouldnt be so difficult, isnt it? CW Cards already work at 32, 44.1 and 48KHz... 96KHz seems to derive from either 32(*3) or 48(*2).. is it so difficult to make them work at 88.2 (ie 48*2)?

To me it would be the preferable samplerate, since it offer almost whatever 96KHz offers, plus it is a lot easier and accuarate to downsample to 44.1KHz...

I wonder if any other people here agree with me..

With my system clocked externally to Lucid clock at 88.2khz the system appears to be locked, although showing 96 khz. Haven't tried recording anything though... I only use 96 khz for mastering purposes. Going to try it on an upcoming acoustical project I'm offered to do.

I tried running some stuff at 96K, but when the DSP load got too high (perhaps halfway full) I started getting DSP errors and PCI overflows. I think you'd better stick to 44.1K for now.

take an hour and read this thread to interesting info on high SR's:

and this one regarding 44.1-88.2 and 48>96

Thanks edmann, I read (most) of that.

Looks like I'll just stick with 44khz.

Lot's of pro engineers swear by 96Khz but since I'm just a lowly creative type I hardly need to offer my clients (I have none) the highest quality levels.

Lot's of people say 96Khz is great for VST instruments but since I mostly use Creamware stuff I hardly think I'll get a huge benefit. The benefits of Creamware are great sound at 44khz.

The only VST instruments I use are software samplers and from what I understand they won't benefit as much as VST synths at 96Khz .

So my conclusion is...it's not really worth going to 96Khz...for now. I'm going to stop messing around and get back to the music.

Dan Lavry- of Lavry Converters - states that the optimum SR is somewhere around 65-70 khz, and as one goes above that the sound quality degrades. There is a thread onthis at pro.rec.com

Nika (see link above) - who really knows his stuff - illustrates how audio is different than video w/re to resolution - and that at 44.1 or 48, one is acheiving great results which do not improve with higher SR's - i.e. once it is "full" there is not "fuller". Nika even illustrates how the "higher SR = better DSP" theory is a myth.

I have read some engineers mentioning that low end suffers at the higher SR's
