Hello, can anyone tell me what the maximum buffer size is for this unit in windows XP?

I am using some very CPU-intensive plugins and I need a buffer size higher than 1024.

If anyone has this card, can you please check for me?

I have searched in the manual, but as is the case with most sound cards of any brand, it does not say what the maximum buffer size is. Nor does it mention it in any of the promotional literature as far as I can see.

I have searched this forum as well, but most threads seem to be about how low the buffer size can go

Any help appreciated.
