Is there a sample rate thats best for DIVA and Zebra output quality?

or does it even matter?

I use Cubase 8 and usually I use 44khz or 88khz. But I wondered if 88khz is even necessary?

What is u-He recommending if at all to get the best quality?

using channel effects (some of the have oversampling, but not all have that option)

dont want aliasing and such.

I think Zebra is best at the higher rate...

44 kHz will prevent aliasing up to 22 kHz which is beyond human hearing range. If you don't believe me, look up the Nyquist Frequency. He's probably a lot smarter than me.

There are a few modules in Zebra which weren't designed with 96kHz in mind. Those are e.g. the reverb, the comb filters and some of the filter types. I think we fixed most of the issues over the years, but the "LP Formant" option may get very loud at high sample rates. I hadn't had an easy fix for this, hence I would recommend to look out for such quirks. If you find any, please don't hesitate to let us know.

Curious about this as well...
I'm using 48kHz, but wondering if I should "upgrade" to 96kHz...

So are you saying Urs, that the plugs were developed mostly using 48kHz and that there is nothing to gain by using 96kHz?

Good to know. I suppose 44khz / 48khz was the development testbed though. thx for the Info!

thx but this is talking about playback and recording (which is mainly dependant from the AD DA Converters btw. they have more information for the low end with slower frequencies..)

anyway I was referring to processing sample rate. Converter Quality doesnt apply there - its simply the maths.

I remember in 2001 when I used Reason 1 and switched from 44khz to 96khz it was night and day. I think reason didnt use internal Oversampling at that time.

And instead of making hundreds of hours into listening contests to find out the quality -> sample rate connection for u-He synths etc. I just asked in the thread - cause I have become a mainly Zebra & Diva user in the last year.
The quality of the synths is incredible! So I try to optimize my performance accordingly. lower sample rate means more running instances of the VST instrument. (less need to bounce / freeze)

Higher sample rates can introduce unexpected problems. I keep using 44.1kHz and oversampling whenever possible.

96khz sounds better than 44.1... for all u-he synths.... Zebra especially though... and as Urs mentioned, the formant filter is a bit wonky as far as levels. Also, the comb modules can sound different enough that a preset wont be exactly the same on both.

Diva I can hear the difference in the high end in certain cases, but it's overall small. Zebra has more of a difference. Bazille can have a fair bit of difference too, depending on the type and intensity of modulations...

Still, each person has to decide whether the gain is worth the price.

I wish my host could render synths at 96 and everything else including recording and bouncing at 44.1 or 48

no the first part is about playback and recording but the second part is about foldover distortion and aliasing, the author suggest to use oversampling to minimize this problem

thats the conclusion I came also too. problem is amny plugins havent a oversampling settings, and some are not transparent -e.g. you dont know if it oversamples internally.

therefore I asked u-He.. I guess the VST of hin use oversampling of some sort. voxengo also has very good vst plugs..

carrieres · Post by **carrieres** » Wed Dec 17, 2014 9:16 am

so you are stuck with 96Khz

Painmooser · Post by **Painmooser** » Wed Dec 17, 2014 6:30 pm

I did some mixdowns in 44 khz and didnt notice a sudden change in quality of the product..

so for now I stick to 44 khz 24 bit using Cubase 8 and mostly u_he / Voxengo and Native Instruments plugins aswell as high quality audio samples..

8 years after this conversation, most computers handle higher sample rates without problems. I’m still unsure whether there could be any benefit with regards to shifting aliasing beyond the audible frequencies. What’s your current take on it?

is there a recommended sample rate?
