WHen i use 96khz, dsp unexpected overload arizes when selecting minimax, and sometimes with other device. On 96khz dsp meter reaches the half of the whole power and overload again. Sometimes i am asked to reload dsps, some other times i have an error on pci...

Minimax doesn't work under 96khz.
Btw, stay away from 96khz, or know what you're doing.
Do a search and you'll know why, it's discussed till death :smile:
Now start a song :lol:

I read the discussion taken a few months ago about 96khz. Huge subject.
But i have to say that after minimax makes this unexpected dsp overload, when i load it without samplrate choosen and select 96khz afterwards, it works! At this moment, minimax is on 96khz with 6 polyphony. Just to inform(This is what's written on the samplerate settings, don't if its true).
At the moment i don't feel the need for exceeding the samplerate of cd. 44.1.

From the creamWare Shop about the minimax;

Minimax
The Analog Synthesizer
Art.No. MOP-63E1

Minimax is the perfect emulation of one of the most-loved synths of all time. Never before has an analog synthesizer been digitally modeled with such precision and perfection. And Minimax has it all: the powerful oscillators, unique filters, lightning-fast envelopes and many more features that made the legendary original a cult instrument. You will definitely love it!

System requirements: DSP board, software version 3.1 or later, PC or Mac (no OS X)


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

It is not stable because causes errors, but if you load it you will see that it sounds sharper. I don't know if it is better, but it is different than on 48khz. Try it please, i am interested in your oppinion.
After the first error, press cancel, then choose a polyphony(you can leave it to 1 if you want), then choose sample rate. If error appears again chang the polyphony a little lower, and sellect again 96. Try it for a few times and it will be loaded.
Thanks,
ARCADIOS

a user will ALWAYS find a way to make something work that isn't supposed to, regardless of what's documented, what you tell him (or her) or how many errors are reported along the procedure :lol:

And why it sounds "better" wider and sharper in 96khz? Is this sound over the wanted result of minimax?

if it really sounds wider then you're supposed to have a phase problem.
you know the trick to widen stereo, don't you ?
and a chorus effect is much appreciated on a lot of sounds...

imho that's the reason why you preceive it as better, and if it sounds better for you then it IS in fact better :razz:
even if your conclusion is wrong - who cares if it's a cool sound ?

but if it turns out that my guess is right - it's really only a guess - then you could modify your setup a bit and avoid the 96k burdon :smile:

there's phase compensation module by RedMuze (from Adern) which allows you delay channels in the sub-millisecond range.

while originally intended to correct timings, it's also great to misalign things.
I have it (for example) on my bass: each pickup comes in on it's own channel and I adjust the natural interference of the 2 pickups arbitrarily, which gives it an enormous tone range :smile:

cheers, Tom

ARCADIOS, do the envelopes get faster/snappier with higher sample rate?

astroman, maybe it gets some more air, some freq. headroom, and more natural highs with less aliasing?
more has been done with less

Atom, you probably refer to the strange effect some old plugins (like the UKnow) produce at 96k. They indeed get a lot more highs, but the rule doesn't apply always (and it has never been explained officially afaik).

I don't have Minimax, so I did a samplerate comparison with Interpole (supposed to have the same filter algo) and Profit5.

When I switched the filter to 96, sometimes there was a rise in output level up to 2 dB...
easily enough to give the sound a higher quality impression :wink: but absolutely no change in the basic sound. I choose hi resonant sounds which were about to fall into self oscillation on a drum loop, so IF there would have been an influence on the filter, it would have caused side effects for shure

On the Profit I couldn't tell any difference at all, but possibly my ears were already fatigued :roll:

cheers, Tom

my opinion is that everything in 96khz sounds different and in some point "better" cause it have higher analysis when the waves are created, the env´s are faster the headroom in the mixer's (inside synths) are bigger, i don´t know if it is just some raise in the volume or some phase shifts, everything is at higher "quality" (bit-wise), that's why i create some bass-drum mixes from modular in 96khz and then downsample, everything is ¨rounder" creaspier... (if u want these things anyway)
the dsp calculations degrade the signal) so better analysis less obvious the degradation (thinK of graphics, the pictures are printed at 300 dpi but all text and vectors at 2540, just print text at 300 dpi and you 'll notice the difference)

Interesting, Tom. My bass (Rickenbacker)has a stereo jack which I've never used - I think I'll try your method.
How do you treat the 2 signals before A-D (direct box, comp, pre-amp)?

good question, Dave - it's a thing that really confuses me...
I just plug it into the A16 :eek:
then comes the PhaseFix Stereo, then Wavelength Mixmaster, finally Celmo's BassAmpSim

the Mixmaster is a small DJ style mixer with 2 stereo pairs and a crossfader
1st channel gets the left out of PhaseFixer, 2nd channel the right out.
this way the level of the pickups is adjusted individually and the crossfader controls the mixture, while outpu level and stereo image remain constant.
compression, drive and fx are handled by Celmo's BassAmp.

as mentioned I find the output level of the instrument stangely high for a passive thing.
For quick and dirty exercises it even works with a Boss DR110 drummy, which has a plug called P-Bus below the phone jack, so one can play lines to a steady beat :grin:

cheers, Tom

astroman - can you point me to that mdl - is it a Flexor-M3 patch or a device?

Thanks,

...edit...

I found it
