Sorry if this as been asked before but I was wondering why ALL u-he products have 16 samples of latency? All of them.

Ok thanks. I've read through it and it seems there's a future version of Uhbik with a "no latency option" but no word on Zebra, ACE or MFM2.

Oh, Z2 and ACE have it too. I might need to document it though

On the other hand, updating documentation is a major goal for the next couple of weeks (as is x64), hence I think it might happen soon.

Thanks for your answer Urs but my original question was why do you need it in the 1st place?

And when you've said Z2 and ACE have it too, do you mean the the switch for zero latency?

And about x64, is it for all your products?

From other thread:

"I process everything in blocks of 16 samples. This allows me to do optimisations that otherwise would easily yield 2-3 times the cpu usage for the same algorithm.

Why do I need latency for this? - Because some hosts are so "smart" to outsmart badly designed plugins and process them at irregular buffer sizes. If every host would just use geek-friendly 16-float aligned buffersizes such as 32, 64, 256, 512, 2048 then there would not be a need for any latency."

So Urs, since the hosts I use are "geek-friendly", is there a simple method to switch of this 16-sample latency for Zebra 2.5 ??

lol no wonder all my bass lines sounded off

16 samples of delay is inaudible at a 44.1k sample rate. It's like less than a millisecond.

.036 msec, and even shorter at faster sample rates

remember that song you commented on where my the bassline seemed off or out of time? well I compensated in FL studio with the 16 sample delay compensation in the mixer and now it sounds in time again... seriously!

it shows up as 0.36msec to me...

Yes, I'm not good with decimal points

But still, that's just a third of a millisecond... Can you really hear the difference?

yeah I can clearly hear the difference, it even throws off my songs since I use very fast tempos. I set up to 2 channels with it, laid a bass line down and panned each instrument left and right. One channel had delay compensation the other didn't.
