96 kHz polyphony

I got my Minimax not long ago and have been testing it for a while. I'm a bit surprised about the low polyphony I get in 96 kHz. I can only get one or two voices on 15 DSPs. It's not about lack of DSP of course, but the STDM connections between my 3 cards.

When I do down to 48 kHz most patches will yield about 10 voices.

I tested with Lightwave as well, it gives 14 voices at 48 Khz, yet only 2-3 at 96 kHz. I'm a bit surprised that the relationship between these two sample rates isn't more linear, but it's probably an STDM thing I don't understand.

I did change the ULLI settings to the lowest option, and this helped somewhat with Lightwave, but with the Minimax there was no noticable gain.

What kind of polyphony do you guys get - when working in 96 kHz?
(And have many cards / DSPs do you have?)

afaik that device isn't intended to be run at 96k, as it would conflict with the internal oversampling - it already does it's job at a high sampling rate.

Do you mean that the anti-aliasing process is different among the devices?

yes, the filter is highly oversampled.

the description in the cw shop always said:

"Please note: 96 kHz operation is not supported by this plug-in."

Funny, I get here 7voices on 18DSP's(at 96Khz) .But without any mixer loaded and with a PCI overflow and DSP error. It seems that after this error if you change the sampling rate at 44Khz and after that at 96Khz again it works... maybe the cards reallocate resources again on the DSP's.
Minimax sounds a bit different at 96Khz, but not much, and I'm not sure wich one is better, 44 or 96. Usually it's 96Khz but this time is unclear, meaning that you will not lose much if used at 44Khz, but you will get extra voices.

high samplerates are for hiding inferior filters........

That's true, my only problem with that is I that all my projects are 24/96, that's why I prefer using Minimax at 96Khz, otherwise is almost the same as at 44Khz, and I don't need more than 4 voices for Minimax.
