Scoped up to the eyeballs

What a great day. Sharc & I got our secondary Scope system up & running again. It's just 2 x 3dsp cards, but with the Adat interface & a Luna 24/96 I/O box, it makes quite a powerful little second system. It's running Scope 4.x, has the STS-3000 & Vocodizer + as many free plugins as we can throw at it.....

Awesome...

It all went well install wise apart from the cset.ini file not installing properly. It was missing a '/' from most of the path entries which was screwing up the menu structure recognition in the Routing Window etc. Just had to edit it & put those in there & it all works a treat.

would that 13ms be an issue if you are only using scope fx (not asio)?

[Tau]

You are right adat in and out, no ASIO and the 13ms should not matter.

Hi, could you explain this a little better? I thought the latency set in the ULLI is valid for all Scope processing...

thanks,

Hi stardust,

Do I perceive some doubts ?!
For audio at least, the only latency is the AD and DA onversion time (close to 1ms for AD/DA) as it is proessed on a per sample basis ...

Strengthen your faith, we 're all believers

For audio? Then, where does the latency come in? The 13ms is form the D/A A/D? So ADAT doesn't suffer from this? But Asio modules don't need A/D, so shouldn't have latency either if you use them for the same FX Send/Return purpose. Is this correct?

[Fluxpod]

Latency is still there.If you have scope cards in a second pc connected via adat and midi you can notice this.Its the driver.
Maybe you can find a "ssd"(Sore sick deal) on a luna/electra/pw-sampler card to get to gen 2 latency.

[garyb]

not between computers via adat. that's a couple samples at most.

...It's just 2 x 3dsp cards...

IMO it is worth only also for the modular 3!
Even better than Clavia Nord Modular 2 at a fraction of cost...

Hi,

If you want to chek for audio delay:
Send a sinus signal whose period is twice the expected latency to the other card and sum up with the original signal. As the signal sent will be affected with your latency, it will come back out of phase and the sum will result to 0 if it's real.
So for a 13ms round trip latency, you have to send a sinus whose period is 26ms ( 38,4 Hz).

ULLI latency = client - host delay;
(scope -> cpu)
if you send audio to a host application and back again you need 2*ULLI; at least !!
there are a lot of native stuff adding a lot of additional delays;
there are even scopeplugs that add latency;
----
you cannot trust the values shown in some apps. btw.
'global variables' not updated and so on;
thats why i said in another discussion here you had to measure to get sampleexat values;

good vibes

Hmm,

I might be wrong but stardust discussed about straight Scope <-> scope latency not Scope <-> cpu.

cheers

You're right of course, but we don't have a modular license for either of the cards.

[Shroomz~>]

I wouldn't even be worried about latency tbh. It's not worth it. Your ears are good enough to know what sounds right when you shuffle around the sample delays on your main mix (main system based). We're mainly going to use this second system for testing Scope plugs we make, but also for sound generation from synths, samplers etc that'll be recorded on the main system. Using it that way, we'll have more of an issue with the latency of midi than with any audio latencies.

really good point - what's all that surgical construction stuff anyway ?
