Motu originals 828 and aggregate device problem

hi again, thx for friends who try to help me some days ago..i can´t fix the problem
I use a powermac g4 867 dual with 10.4.2,logic pro 7.1 and 2 motu original 828(the first model, whithout setup bottons and screen).I must use aggregate device option to get their 36 i/o, but logic crash and/or make noise on the 2nd rec, whith hardware problem window and more...i still have to work on mac os 9 to use both motu!!! Must i activate the "resample option", or clock..or any solution to fix that??
please help.
thx for all

I tried using a 6 to 9 pin firewire cable to connect the Motu Ultralite to it's own port on the Powerbook with the Motu 896 HD on the other firewire port. This didn't seem to make much difference. When I turn on 'System Performance' the Audio section runs about 90% and will often peak out.
Anybody else having similar issues? Just curious if it is my device, if I need a faster machine or simply a problem with the Aggregate device driver in OS X not working very well. Any advice appreciated. Thanks.

Latency and Aggregate Devices

Hello. I'm using an aggregate device for the first time. I have a Line6 Toneport GX and a Presonus Firebox; I combined them into an aggregate device in Audio MIDI Setup and can access each interface in Express. Pretty cool.
However, latency seems to be an issue. For example, there is noticible latency when playing through the Toneport - to the point where I get thrown off while trying to play live. I disassembled a number of components and tried just the Toneport by itself and found the latency to be a non-issue.
Do aggregate devices introduce the latency of each interface? Does the fact that they're on different busses (one USB 1.1, the other FW400) contribute to my problem?
Is latency something that using a faster connection (say, the USB 2.0 on my laptop from work) would help correct? Finally, would the faster processor from my work machine solve this issue as well?
Thanks, all.
James DiStefano

USB 1.1 is slow. Many devices just wont work on it.
If you use just one device or the other do you get latency then?
It maybe that there is a bottleneck of data from the firewire port waiting for data from the USB going into the aggregate device. To be honest I don't know how the aggregate device works, but you definitely have 2 very different data transfer speeds into one device.
If the USB device, whichever it is, is USB 2 compatible, you can get a USB 2 pci card for about £15 UK, perhaps 20-30$ US with 4 or 5 USB 2 connections.
You are using basically the same setup as my previous machine (G4 1.25GHz dual). Installing the USB 2 card opened up a whole new world for that machine.

Aggregate Device problem!

hey guys, im new to this, but i just got Logic Express 7 and i had a problem with my output. i use a fast track for my input. i found out i needed to create an aggregate device to get my output working, so i did, but my options for my device are built- in input and built-in output, and fast track. i saw that everyone selects built- in audio, so what do i do? thanks everyone

You may want to read the "Audio Devices" PDF on this site:

He covers aggregate devices in detail. I believe he discusses creation and usage of the aggregate device.

Help? Aggregate devices not working in Lion

Since buying a new Mac Mini Server for my audio work using Logic Pro 9 I cannot use aggregate devices. The system preferences as well as audio midi setup will not remember my aggregate devices that I create. Also when using them the audio becomes glitchy and a terrible noise happens. I didnt have any issues like this in 10.6.8. I cannot believe that Apple would let this happen for so long. There are many people in the pro audio world that rely on using aggregate devices and with them not working three versions into Lion this has become maddening.
This is not a third party issue. This is not a hardware issue. This is a serious problem that takes the saying that "Macs just WORK" and flushes it right down the toilet.
I spoke w a guy named Steve at Apple pro audio and he couldnt get me off the phone fast enough. What the ____ Apple??
PLEASE someone fix this? I wont try 10.7.4 as it seems to make Logic work even worse.
Please...I do not want to have to go back to using pro tools and PC's.

please and thanbk you Eriksimon! Full details - Mac Mini Server running Lion 10.7.3, Logic Pro 9.1.7 I use up to three Metric Halo 2882+DSP 2d units with the latest MIO console, drivers and firmware. Many other Metric Halo and other multiple device users are experiencing this and it is maddening. Ive been on Logic since 7 and am a analog-digital component level tech / electronics engineer / audio engineer with a decent knowledge of software.
I also use up to two McMix (now Avid artist mix) with latest version of Eucontrol as well as V-control pro with my iPad to control Logics transport etc when not in control room and a Novation sl49 compact USB keyboard with latest Automap version All that worked together quite well on 10.6.8 - logic 9.1.5 on my late 2008 Mac Book Pro but that system was slow...so I was hoping that Apple had Lion "in a cage" when I went out to buy this new Mac Mini Server.... I guess I should have waited.
I am having these aggregate device problems on a totally new from Mac Store Mac Mini Server Quad Core i7, did a clean install of Logic and the Metric Halo software /driver /firmware package.
Nothing else installed on this new Mac Mini but Logic 9.1.7 and MIO package.
Please....help get this bug fixed??

Glitch aggregate device

Hello
I'm having a problem on my macbook pro 15" 2.53 intel Unibody. I upgrade to 1.6.7. When I open any recording software and choose the audio device and aggregate device,(I use a Focusrite saffire pro 26 and saffire pro 40) after 3 or 4 minutes of use starting with glitches and disturção. Does anyone have the same problem? What is the solution of this bug? With version 1.6.3 did not have this problem.

Hi,
What exactly is your aggregate device ?
I have a Hollywood Dazzle DV Converter that connects over Firewire that is seen perfectly well in Panther, Tiger and Leopard and the relevant iChat versions.

Combine Motu 24I/O and internal spdif with "aggregate device"

Hi,
i'm using locic pro 7 with a motu 24 i/o for recording e.g. vocals. To improve the quality i plan to buy "benchmark adc-1 converter, but there are no digital inputs on my motu. Can i combine the 24i/o with the internal spdif input? The motu runs at 64 samples without troubles. if i combine both via "aggregate device",what about latencies? is the latency of the motu as high as the internal spdif? Should i better buy a digital card (rme)? Does anyone know a good digital card (pcin and not too expensive)? Thanx a lot,
Oliver

Logic 9 issue with original motu 828 and Snow 10.6.2 on a new imac 21.5in

Original Motu 828 and Imac Snow 10.6.2 os. What do i do to get this motu to work with Snow on the new iMac 21.5in model. I downloaded drivers from Motu which i get crashes. I heard some people are having no problem while others like myself having problem.
So to those who has this type of setup how did u do it.
I uninstall driver because of crash issues. I also trash the prefs but no go.
without the driver motu 828 doesn't crash when plugged in firewire port using cord fw 400 to fw 800 but system prefs and logic doesn't see the motu.
Has Motu stop supporting Snow to work with the original motu 828 and Why doesnt motu answer their phone.
I dont think i will ever buy a motu product if their phone is always busy. Dang... Cant even leave a message with motu by phone and i need my system to running.

My Mac Pro crashes all day since i updated or installed the Motu card.
I have qty 3, Motu 24/IO's, and 1 828mk3 and 1 896 mk3.
I updated to snow and then downloaded and installed motu's drivers and my Mac crashes all day long.
Left Support ticket on MOTU site and they are so lame they can
't even answer a support ticket let alone answer the phone.
I am hostage to a bad sompnay!. I own the PCIe 424 and all the 24/io's etc.
Is there another company that makes 1 card that will support 80 inputs of 96kz audio? I sure need one that only takes up one PciE slot!!!
Also if you have Ethno instruments it will crash your mac.
Is ther a script or master un-installer so you can remove all of Motu drivers/
Also try opening your console, and watching...it looks for a fw/usb device that is not recognized anymore. Guess MOTU wrote some good dirty code again that causes havoc on the buss!.
ANy ideas on another audio system that is snow lepord campatible?

I am trying to use 2 MOTU 896's as an aggregate device in Logic Pro 8

I am using Logic Pro 8 on a Macbook Pro OS 10.6.8. I am trying to use 2 MOTU 896's as an aggregate device to have total of 16 inputs. I am daisy chaining the 896's via firewire. I can select channels 1-16 as inputs in Logic. I am getting signal input in channels 1-8 in Logic. However, I am getting no signal input in channels 9-16. I've also tried using ADAT light pipe as output from the 2nd device to the 1st one and that didn't work either. I have created the aggregate device under audio-midi setups and I've set the 1st 896's clock source to internal and the 2nd 896's clock source as the 1st 896. I've also tried both 896's clock source as internal. Has anyone had any success in using 2 896's as an aggregate device in Logic Pro 8? I need to use this setup to record a large band. I would greatly appreciate any tips that anyone has. Thanks.

David,
Learning is not a bad thing, I'm just saying what you thought MIDI did is in error, you're not the first.
Here's an article explaining what MIDI is and how it works, it probably seems less than you thought it capable of but the fact is, since it's standardization in 1983 it completely revolutionized electronic music. By the Way, the designers of the Prophet 8 (Dave Smith & Sequential Circuits) had a lot of input into the MIDI protocol, in fact, if you had to say one company/person came up with the basics of MIDI it was Sequential Circuits. They also came up with the first polyphonic, fully programmable analog synth. I had a very basic MIDI studio at the end of 1984.

I cannot get MainStage 3 to find the Aggregate Device I am trying to use for input. I have two USB interfaces and need to use both for input.

The MainStage 3 Audio preferences window will not find the Aggregate Device input. I have both an Apogee Jam and a MOTU Mike Ultralight in USB ports. The Audio aggregator finds them and treats them as one device. The Aggregate Device does not show up in either Logic or MainStage. However, unlike Logic, MainStage does not show "System Settings" an input device.

The iphone 3G can only support 4.2.1
There are no newer updates availabel for this model.

I have three Blue Yeti USB Microphones, and when I try to create an aggregate device in Audio MIDI on my MBP it lets me select two microphones but not the third. I need all three for a podcast, any solutions?

I have three Blue Yeti USB Microphones, and when I try to create an aggregate device in Audio MIDI on my MBP it lets me select two microphones but not the third. At first I thought maybe the third microphone was just defected or something but I tested the mic individually and it works fine. It'll let me use two Blue Yeti's and another microphone but not three Yeti's at once.

The problem is that the mac chokes on having 2 identical mics attached at the same time.
Ive had 2 identical USB AT2020 mics connected at the same time on both macbook pro and macbook Air.
The "Yeti" mics, are, lets say undesirable, and low to mid computer consumer mics.

Aggregate device: BIG PROBLEM with mbox(digidesign)

i must admit, meanwhile i am truly desperate...
MAYBE ONE OF YOU HAS THE SAME EXPERIENCE AND HENCE A SOLUTION TO IT... problem is as follows:
i have a mbox1 connected via usb to my ibook g4 1.33ghz (ppc) and want to make an aggegate device in the osx 10.4.9 system preferences (audio-midi-setup) together with the built-in audio in order to be able to use 4 audio outs simultaneously within NI traktor dj studio 3 so that i'd have 2 channels for master out and the other ones for monitor.
but: when trying to make the aggregate device, mac os only shows up the built-in audio. the digidesign mbox seems to be vanished, although i can use and choose it seperately as my main out. but not in the latter mentioned dialogue. so what the heck is wrong? btw, i have coreaudio 7.3 installed properly (the one that fits for ppc-macs)...
- is it maybe because of clocking issues?
- built-in is on 16bit only, the mbox is on 32bit... what about this?
- is the mbox1 (folks, i just purchased it 5 years ago) not working with newer systems anymore in full effect?
- is it the coreaudio-driver itself (although it is visible/selectable in audio preferences)?
PLEASE HELP! I DONT KNOW WHAT TO DO NOW ANYMORE...
sincerely yours

any suggestions out there?
plz help!

Aggregate device on the same firewire bus (fireface 800 and Lightbridge

Hi,
I'm trying to set up a aggregate device with my old RME Fireface 800 (on the firewire 400 bus) and this new M-Audio Lightbridge. But allthough I manage to create the device, there is no sound at all. The Fireface acts as digital master via a word clock cable. The Fireface are connected via a 10 m. cable to the rear connection (on my nes Mac Pro) and the Lightbridge are connected to the front. I know it's the same bus using those two connectors, so do you think a separate firewire board would be a solution?
Regards Stig

So the firewire "bus" and a firewire "interface" are the same thing then? Excuse my ignorance, I've just been put in the position that I needed to know this for the first time with this audio interface problem. The things I used my firewire ports for just worked without me having to learn much about it up until now. Also, I found some posts that the card had some issues functioning in a version of Leopard. I'm about to upgrade from Tiger (finally) directly to Snow Leopard. Do you (or anyone else who sees this) happen to know if there are any issues there? I appreciate the help very much Rod.

My audio aggregate device is not stable in Mountain Lion, it was fine before I upgraded from Snow Leopard - every time I reboot the computer it loses the configuration and so it is not available in Logic Pro

My audio aggregate device is not stable in Mountain Lion - it was fine before I upgraded from Snow Leopard. Every time I reboot the audio aggregate device (MOTU TRAVELER, MOTU PRE8 1, MOTU PRE8) has to be reconfigured so that it is available within Logic Pro.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)

HT3956 I have tried to connect three MOTU 828mk3's using this new aggregate device listed here, but it wont work any suggestions?

Hi
I am trying to use three 828mk3's with an analouge desk and after creating a new aggregate device in Audio/midi set up it doesn't seem to work, also the blue shaded are doesn't allow me to move the volume up or down?
Any suggetions?
Thanks

Hi
The situation is like this, we have ordered 3 motu 828mk3 AI's to replace old avid hardware. We have a 24 track analogue BIG desk made by langley. The issue is that Logic 9 and Pro tools 10 don't want to use all the sound cards together, if we change the playback engine to MOTU 2 then we can use channels 9-16, then the 3rd one for channels 17-24 etc. Looking around at forums and other sites as lead me to set up a new aggregate device in the audio/midi set up in utilities. Again after we tried this it still doesn't allow us to use all three together. Motu state that you can daisy chain up to 4 devices, i have sent an email to MOTU but have yet to gain a response.
