I am hoping that my KVR brethren are different and will assist as i haven't been able to get help anywhere else.

OK, here goes:

I don't know how i am this lucky but the store is allowing me to swap my useless 8 month old Duet 2 which is bug ridden with terrible latency (as well known) for a new interface and i am thinking 828MKIII or babyface.

I have a motu FW ultralite now and the latency and performance AT low latency is just exceptional but on this imac i really prefer to use USB if possible..as i have two hdd on firewire bus...

The reason the 828 is a contender is because of hardware fx monitoring and the fact that i can use the firewire port if i decide to or ever need to, where as the babyface is only limited to USB.

Actually for that matter i would love to know what the RTL in logic of the babyface is as 32 and 64 samples at 44.1 or 48

I would also like to know if unlike the duet, the babyfact CAN work without crackles and pops at such low latency in logic.

lol. But back to motu...

But please, there must be someone here using a motu hybrid on mac in USB mode who can tell me if 32 and 64 buffer size work reliably and what the actual RTL of the USB is, i know what the FW is already as i have the FW only ultralite, but really want to know if the USB is as usable.

Thanks so much again!

so basically what i am asking, even if you use FW, if you have a hybrid. Pull fw cable out, put usb in. Launch audio program. Look at input and output latency at 32, 64 and 128 samples at 44.1 k.

Press play for one minute on a medium sized project at 32 samples and see if it can cope.

That's it, it should take no more than 5 minutes at the most of your time and i will be sincerely appreciative as my deadline to get an interface is FAST approaching (LONG story)

ooops i put this in wrong section, please put in computer hardware mods...

There is absolutely no reason to put your interface on usb just because you have 2 drives on firewire.

I run an 828mkII and 2 drives on firewire with absolutely zero problems.

Firewire has FAR bigger bandwidth than usb and can stream several hundred channels simultaneously with no problem.

yes but i am saving for a uad satellite duo and that is the thing.. That is a known fact that the uad wants the ENTIRE fw 800 bandwidth for it's plug in count and that's why i won't bother with a quad cause it can't be maxed out over firewire with many of the higher plug in instance types like the older plugins.

Even streaming off he two fw drives will definitely cut off the uad instances, i have done some serious research into this and spoken to uaudio as well...

i should have mentioned that...

i won't be able to afford it for another few weeks but when i do.... i just think a hybrid interface would be amazing to have

why 146 views if you don't have motu hardware?

No answer at gearsluts over 8 days, here, or motunation.

No one in the world is using a motu hybrid interface obviously, no one, and if they are, they couldn't be bothered giving me 5 minutes of their time.

I will never help anyone again. I am so over this bullshit.

Well I read this topic because the subject header got the better of me. Wish I could help, if I could I would but the only MOTU gear I have is 4 of their MIDI interfaces. I know how frustrating it can be trying to gather information for something and coming up empty but I also know that searching for that information can lead to a lot of unexpected learning as well.

Can a store not assist you with this experiment? Regardless, good luck with your quest

1st world problems.

I'll tell you what: first of all, Firewire interfaces from both RME and Motu certainly have higher actual latency at equivalent buffer sizes because of the additional "safety buffer" they -have- to add for the Firewire driver. I've read user reports that Babyface works fine with a 32 samples buffer on Mac with Logic Pro. I wouldn't count on 32 samples buffer being completely dependable with -any- interface, and there are sometimes problems with the hosts, plugins, etc. with that latency. That said, RME put a lot of work into their USB drivers for Babyface, UC and UFX, and users report excellent reliability (wasn't that expected? it's RME). Between those choices, I recommend that you get Babyface. There are no "bandwidth issues" either (it's USB 2..), the drivers are better than everyone else's and the overall quality is excellent.

Thanks but still need motu figures

i already got banned from motunation about this

most people at gearslutz agree the admin was a little, um, er, harsh

I hope people like that James Steel are at KVR so we can get them banned or furthermore humiliate them for the tripe that they are.

A simple first ever warning would have sufficed, i guess he looks like the bigger dick. I perused that forum now and then and was a member for years but apparently you have to walk on eggshells when posting.. that, i did not know

I agree too

And sorry.. I dont have a MOTU interface, so I'm afraid I can't help. Good luck though!

Hey guys... is it because no one actually has a hybrid?

i just want to know i am not going mad and it's because no one has a hybrid rather than not wanting to help.

It's just too weird.


Even at GS

I am sorry i got a bit shitty before but i am going on three weeks total trying to simply find latency figures for *any* motu hybrid interface.. surely you can understand that's frustrating.

Alot of other companies to report their latencies so i partially blame motu who are so hush hush about their cards specs... mind you their firewire latency figures are outstanding,

i have committed to a uad duo now which will take the entire fw bus of my imac so i DO need a USB interface, i have no choice.

Put it this way...

On some of the less hungry plugins on even a DUO (that's why i believe there is no point getting a firewire quad), you max out the firewire bus before you max out the dsp, and that's if you have the total fw 800 bandwidth dedicated to the satellite only. The only benefit for a quad is for say the manley passive which hits it's dsp limits well before the firewire bandwidth limits (for example)

cheers!

I guess James was having quite a bad day. He definitely needs a


I don't have a MAC or a Motu interface but I have been eyeballing the microbook 2.. the hybrid looks nice but out of my price range. Hope you finally get the numbers you desire.. frustrating it must be.

Almost would be tempted to go to a music store where they have demo MAC displays and ask them to install one just to see

oh they have everything but motu interfaces IN stock.

I have seen numbers for all the other interfaces by going in and telling them i want to know RTL and also if the RTL is reported correctly, they even let me do loopback tests to check.

But i am limited when i can go as it depends on if my back is strong enough that day to get in the car..

and now i have been to three places and they all sell motu but none on the shelves, so i kind of um, shelved that idea.

But i DID find out that mbox 3 USB2 RTL at 64 buffer is 9.1 and is 2 samples off (mac)

I wouldn't say harsh - just a classic example of a w&%ker being made a moderator and thinking that makes them able to hold their sword in the air and shout 'by the powers of grayskull'

If that is the sort of support that I am going to get, I am staying well away from Motu!
