BPM synced delays does not sync using latency below 25ms 44k

[mantrix]

This is my third post in this part of the forum, and hopefully my last.

When i choose a quicker latency setting then the slowest (25ms 44khz)
the BPM function on the delay effects does not work properly any more.

Let me show you, here using a delay synced to 1/2, the notes hits exactly
the same beat as the delay signal:

ULLI setting: 7ms 44khz = BPM synced effect useless

ULLi setting: 25ms 44khz = BPM synced effect as it should sound

I cant understand this at all. Say i buy a digital mixer with included effects,
even though some latency will naturally occur within the mixer during processing,
using a synced delay effect would never sound that horrible.
Please tell me there is a solution?!
I want this to be a professional soundcard, not only work professionally at 25ms latency!

If its actually not possible to use BPM synced effects BPM synced at lower latencys, why does not the product come with large WARNING stickers? Like does not work properly using lower latency..? I dont want to offend anyone but this just made me go into



I just want to make music, and i want to make music at latency lower then 25ms!!

Forgive me for the lack of patience.

It is a known bug...unfortunately.

You can use a beat calculatir that gives you ms values and select the delays as time values.

Ok.. then i know.. Its sad but i feel the bugs is part of the Scope nature. Its related to Yin and Yan, no one could make something lovely as the Scope system is without a natural balance of some flaws occuring.

Now i will click on the damn 25ms button and make some music! I might try a beat calculator also.

Thank you for your support stardust!

I just think a bug like this should be very easy to fix. Its just very basic mathematic calculations to be redone? It cant be that it CANT be fixed, its just that they have not tried right? Is it something that has been introduced with latest Scope version (4.0) or did it exist in 3.0 also?

[spacef]

it is not a bug and it could be fixed only by not using the pci bus and buffers
Many delays (at least spacef ones) include ULLI corrections that accomodate any ULLI at any samplerate from 32 to 96 khz (and virtually any other samplerate if they existed).
I am pretty curious to see how xite deals with that ulli stuff

I tried setting the delay times manually in ms, but i get the same problem. If i run my sequencer in 120bpm, and have picked 1000ms, i get the same stuttering effect as in the first mp3 example.
???

Only using 25ms latency makes the delay times behave normally. No other fix seems possible.

If you can't deal with it by making manual adjustments - Use SpaceF's delays. They're very reasonably priced, so I don't think it's right to say there isn't a fix when SpaceF just explained to you that there IS a fix.

[spacef]

i thought there was one or several in the device pages (i had one but not sure how it is called or if it is still there)....
you can get the M.U.D. for free. It is a very basic delay. it has input send level though.

Nice one Mehdi. Your new website looks really smart btw.

Hello!

Yes true that is, but its a solution that costs money, and for the moment im not so full of it.
It would be great if i could only buy one delay effect as that would be all that i need.
I downloaded a demo for Echo-35, while the sound was good i felt it was a bit advanced for my needs. I just want a simple delay with a good sound. Synth FX looks like just what i need. But as i said, i cant afford buying the whole package. Also how much DSP does Synth FX use? Im a bit short of that to

Im going to try the mud delay. Thanks for the tip

Also, what currency are being used in the SpaceF shop? $ OR €? I think you should add this to the information spacef, otherwise a kickass looking website.

[spacef]

Thanks for the compliments and heads up. The shop is in euro, i just corrected this (curiously, the currency symbol should show up... but it doesn't....).
I was thinking of making standalone delays again, but i hope it can wait a little bit (a few weeks).
Best regards
