Aggregate Devices, FW Daisy Chaining, Distorted Recordings

I had troubles overdubbing vocals for a rock band tonight; much of each take would be distorted (not like a guitar), with clicks, pops, and a crazy smearing of the voice at times. Instead of using the Aggregate Device (2 Pods daisy chained w/ a FW HD at the end) under audio hardware i had selected only the first pod, thinking that this would free bandwidth. When I changed it back to aggregate, the noises seemed to go away. Does anyone have any experience with this? I would like to know if I really solved the problem or if it was totally random. Do you have to use the aggregate device if the hard drive is at the end of the chain, or the 2nd pod which is connected directly to the hd?

I am currently running two audio interfaces. The only way they play nice is by syncing them together and making one of them the slave. Actually, both of them are slaves to a master wordclock supplied elsewhere. However, as long as one is the master and the other is the slave, there's a much better chance they'll get along. The results are in the audio.

  • Configuring multiple thunderbolt2 devices on daisy chain and RAID 5

    Can multiple thunderbolt2 storage devices connected to a mac mini [ 2014 ], via daisy chain, be configured to work as a single volume on RAID 5?

    Yes.
    Normally you would buy a hardware RAID5 solution like the Promise Pegasus R4 or the Drobo 5D however recently some new software has been released for the Mac to allow creating RAID5 software RAIDs. See http://www.softraid.com
    Apple's own Disk Utility cannot create RAID5 software RAIDs.

  • Audio Distortion on FW400 Audio Interface Daisy Chained to FW800 Hard Drive

    Hi everyone! I’m an experienced Mac user in need of help resolving FireWire device issues.
    I received my 27” i7 iMac a couple of weeks ago running 10.6.2. After a long process of migrating over from my 9+ year old Dual 500 MHz G4 PowerMac tower, I was excited to set up two 1TB drives inside an OWC Mercury Elite Quad-Interface Dual HD enclosure via FW800. I then daisy chained my Focusrite Saffire 10 audio interface (FW400) to the HD enclosure via a FW800 to FW400 converter cable. To reiterate:
    i7 iMac (FW800 port) --> OWC Mercury Pro Quad-Interface Dual HD Case with 2X 1TB drives (FW800) --> Focusrite Saffire 10 audio interface (FW400)
    Although a lot of people may disagree, I wasn’t concerned about having my FW800 hard drives drop down to FW400 speeds because of the slower audio interface. I have read enough about the 1394 FW protocol and its ability to use something called beta clouds, allowing both FW400 and FW800 daisy chained devices to operate at their maximum speeds. So far, so good. The drives are reading/writing data fast.
    As many studio audiophiles have said, you should separate your audio recordings and projects from your startup disk. I’ve done so. However, call me naïve, but I did not imagine that every time my external drives read or wrote data, my audio interface would go into a state of distortion (like raising the gain on a track as high as it can go). When the activity of the disk drops below a certain level, the audio interface usually switches back to clean pristine audio. I am experiencing this within a studio environment and with simple CoreAudio iTunes playback via my audio interface. How is this possible? Am I doing something wrong or is there a blatant limitation with the FW chipset Apple is using for their single bus in the new iMacs? If anyone can provide me with a solution or a convenient work around, I will be very grateful!

    Thank you for the feedback, Rick. To shed some light on daisy chaining FW800 with FW400 devices, I provide the following quote from one FireWire technical article I came across on the web:
    +"The concept of beta clouds allows FireWire to keep all devices on the bus to operating at their maximum speeds. Devices are cluster together on a logical level in a cloud. The cloud operates as a single block at 800 Mb/sec. The borders of these clouds are where legacy devices are connected, operating normally. Each device operates at its highest speed."+
    In short, beta clouds allow both devices to operate at their highest speeds.
    Both the audio interface and the external hard drive enclosure has its own, connected power source.
    I wish I had the option to use USB2 with my audio interface, but it only has a FW400 connection.

  • Trying to record multiple tracks (24) in Garageband with 3 presonus firestudio devices daisy-chained together.

    Please help !! I can record multiple tracks (8) on a single presonus firestudio, but now I'm trying to expand the number of tracks to 24 by daisy-chaining three firestudio devices.
    The three units will sync up properly, and Garageband detects all of the input channels, but the recording doesn't pick up the input signals for the 2nd or 3rd device. It only picks up the signals from the first device. I read the manual and daisy-chained the devices by serial number (lowest to highest).
    Any help would be greatly appreciated.
    Thanks

  • How many FW devices can you daisy chain?

    Have a new iMac w/ one FW800 port. Need to daisy chain eight FW800 hard drives, two FW400 hard drives, and one FW400 DigiDesign Digi002 ProTools mixing board. I was planning on daisy chaining all the FW800 drives then coming out of the last of those with a FW800 to FW400 cable into the first FW400 drive, daisy chaining to the 2nd FW400 drive, then daisy chain from it into the FW400 ProTools mixing board. I know that's a lot of chaining but at the moment those are the devices I have to work with. I have A LOT of video and audio information I need to retain. Seems to me that I read somewhere about a maximum length a firewire daisy chain could be but haven't found any more reference to it when I just looked. All of the devices have their own power supplies so I don't believe they will be drawing much, if any power from the chain. Anybody know of any problems with this setup?

    Thanks for the info.
    I've tried several scenarios and combinations what I've found is that I can put all the FW800 drives in a daisy chain then put the 1st FW400 drive in and lastly the Digi002 mixing board (which is FW400). When I try to add to this any more drives I get unpredictable results. I have therefore bough another 2TB external drive and hooked it up through USB 2.0 and copied many files to it from the older FW400 drives as well as the only FW800 drive that ever game me headaches. It should be noted that it is a Western Digital My Book drive. It seems like it would be a great drive having FW800, FW400, and USB 2.0 connections. In practice, however, I have had LOTS of problems both on my Macs and PCs I tried using it on. I recommend strongly that you avoid using any MY Book drives. I'm having better luck with practically any other manufacturer, including what I would normally consider no names like SimpleTech and Buffalo. Those drives seem much more stable.

  • How to daisy chain thunderbolt devices with only one port

    I am using a macbook pro with one thunderbolt port. Quite a few thunderbolt devices have only a single thunderbolt port (don't support daisy chaining).
    Does anyone know of a thuderbolt hub that adds additional thunderbolt ports?
    If such a product does not yet exist, is it at least technically possible?
    Thanks!

    (1) Thunderbolt does support daisy chaining up to 6 devices to the MBP's port (with some limitations). See

    (2) Note that daisy chain and hub are not the same. However, my understanding is that, in principle, a Thunderbolt hub is feasible. I'm not aware if such a device is already on the market. I guess that whether or not Thunderbolt hubs will be eventually available depends on the demand.

  • Thunderbolt to firewire adaptor does not work when daisy chaining firewire devices

    Hi,
    I just purchased the Thunderbolt to firewire adaptor for my new late 2012 iMac.
    It works when connecting a single firewire device, but when I daisy chain another drive, the first drive disconnects and nothing mounts.
    I am trying a Hitachi G-Raid and a couple of WD My Studio II hard drives. They all work when connected directly to the adaptor, but not when more than one drive if daisy chained with firewire.
    Has anyone got firewire daisy-chaining working with a thunderbolt adaptor? (just to clarify I am not refering to thunderbolt daisy chaining, as the adaptor is an end-of-chain thunderbolt device).
    Thanks

    Yikes, that's sad to hear.
    I can't test it, no TB here, but are all these drives self AC powered, ie. no bus powered drives?

  • Flickering video when daisy chaining firewire devices - HELP!

    I have a 12" Powerbook with a single firewire 400 port, to which I have attached 2 daisy chained external hard drives. I have no problem capuring video off of my camcorder when I daisy chain it onto the end, but when the firewire is sending video the other way, as in the case of "printing" to tape, or using a television during editing, the audio clips and the video flickers substantially.
    I've observed that connecting the camera directly to the computer eliminates this problem. Of course, it's a bit awkward, since I also eliminate my scratch disks (the external drives)! I've tried a firewire hub as well, and it seems that either the extra device or the doubled length of cable is interfering with the signal in such a way as to cause the flickering.
    Has anyone else experienced this problem?
    In any case, I'm thinking about buying a MacBook Pro. Assuming I run into the same problem, I was thinking about adding firewire buses with the Express Card slot. Has anyone done this, or have recommendations for firewire cards that reliably work with MBPs?

    When you say 'flickering' what do you mean?
    If the playback is stuttering, meaning the data rate is not being sustained, then it is a Firewire glitch. If the video is strobing or rolling then it a video issue with the timeline or the capture settings or something else.
    We daisy chained Firewire back in the day on the first edition Powerbook (400Mhz with 10GB internal) and had no issues, that was 4-5 years ago, so your PB12 should be fine with this.

  • Daisy-chaining firewire devices

    Now that I bought a firewire Audio interface (the Presonus Inspire), I am wondering how to plug in my external firewire HD. Both devices have two firewire sockets, I could daisy-chain them in two ways, right? (Couldn't get it to work today, but the cable that came with the interface seems to be faulty). Does the order in which I connect them matter?

    Order shouldn't mater, I've run Computer->HD->FirePod as well as Computer->FirePod->HD

  • Any Limit to Daisy Chaining FW800 devices

    From a review of previous posts, it looks like daisy chaining FW800 devices work well. I have a 1TB OWC FW drive connected to the only FW800 port my iMac has, and I use it for Time Machine. I am planning to add a second 1TB OWC by connecting it to the first drive (which has two FW800 ports. I will then, on occasion, connect a video camera to the second drive, also via FW.
    Anything wrong with that? Is there a limit to the number of devices I may daisy chain?
    Thanks.

    Hi Richard
    +"Fire Wire can work with up to 63 devices on a bus."+ However, +"The number of bus-powered devices you can connect depends on the amount of power available from the computer, and the amount of power required by each device."+

    You should be fine!

  • Daisy-chaining firewire devices on iMac

    I have an intel-based iMac which I have a Lacie HD connected to the 800 FW port (that's connected to Time Machine) and I have a Lacie HD, a Hitachi HD, an eyeTV 200 unit and Lacie d2 DVD-RW drive daisy-chained on the 400 FW port. When I attempt to copy a DVD (of my own making, not a commercial DVD) using the Lacie DVD burner and the internal DVD burner, I get a error message saying the connection was interrupted.
    What I'm wondering is if I need to string these devices in a particular order or is there some sort of firewire hub I can buy to connect these devices to the iMac, since it only has one FW 400 port?
    Any help would be greatly appreciated. Thanks.
    Mike

    I bought a Belkin FW hub and haven't had a problem with it:
    http://www.buy.com/prod/belkin-6-port-firewire-hub-6-x-6-pin-firewire-ieee-1394a -firewire-400/q/loc/101/201955859.html
    My only complaint about it would be that it is extremely light - so light that it doesn't like to stay in one spot and the FW cable connecting it to the computer seems to drag it off the shelf, but maybe if all or most of the ports are being used at the same time (which I haven't tried), it'll stay in place.

  • Aggregated Device & Daisy Chained MOTU

    I am trying to use 2 Motu Ultralites with Logic Express. I have set up an aggregate device in audio midi set-up, and slaved the clock source of the second to the first. The trouble is when I go into logic express and choose the aggregated device I only get the audio inputs for the first one (ie 1-12). I'd expect to see 24 inputs.
    What am I doing wrong? I have spent hours on this!

    I'm guessing that because LE limits you to 12 simultaneous inputs, LE is picking only the first 12 as available. I would have thought you could select which of all your inputs you want to use, but apparently not. Do all inputs show up in Audio?MIDI setup?

  • 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.

  • Daisy Chain a Motu 896HD and a FirePod, can't get it to work??

    I'm trying to Daisy Chain a Motu 896HD and a FirePod, but don't know how to get them to work together. Logic Pro can see them seperately, but I can't get it to recognize them at the same time to use 16 audio input channels. Can anyone tell me how this can be done?
    I know I'm suppose to set one as the Master and the other as the Slave, but can't figure out how that's done.
    I have read in the Motu Mannual how to daisy chain two Motu interfaces, but can't figure out a motu and a firepod. I emailed Motu for help, they said I would need to get help on the software side.
    I've been going through post after post on here, but can't find a similar problem that's been helped.
    Thanks,
