G5 Firewire-ports poor for audio interfaces??

Hello. I have reason to believe that the FireWire-ports on the new G5:s are not really stable enough to handle an audio interface. Storage devices are okay (much less complex protocol).
My G5 constantly loses contact with my Digi 002R interface, or chokes on CPU even on low level usage, and on the Pro Tools forum many users have experienced this. The G4:s had much more stable FW-ports!
For some users it helps to use only one of the two FW400-ports, not both.
Is this a known issue? Has Apple ever commented on this? Does the warranty cover this? (It should)
Niljam, new to this forum

I recently switched from a MOTU 828 running off the FW400 connector on the back of my G5 to a Yamaha mLan-based solution.
When I switched to mLan, admittedly running potentially tons more channels in/out, the internal FW bus "fell over" (connector on the front and the 400 and 800 connectors are all on the same bus no matter it turns out).
I popped a PCI firewire card and the audio stuff worked MUCH better, it was immediate. That's not to say that things work perfectly now... if the machine has been in sleep mode for a while, mLan's autoconnector hangs quite severely, whereby it's not even possible to force quit it... really ugly actually.
at any rate... for 8 in/out, certainly on MOTU, the on-board FW will "do", but it's probably best to get another FW card, especially if you're going to put sample libraries etc on an external FW drive, then you'd want that to be separate from the audio streams...
hope this helps!

Firewire or USB for Audio interface on powerbook

For a Powerbook G4 667 mhz, 768 MB RAM , 2 USB, 1 FW
What's better, FW audio interface and USB external hard drive, or the opposite? Thanks

I find that I have no problems on my PB using my hard drive and my interface daisychained. Obviously it depends on how fast the FW port is too - I imagine on yours it will be FW400. FWIW, I can get 8 streams of audio on to my LaCie with no probs at all, and can run a good number of tracks off it. My processor gives in before my drive...
But it's right, the best combo to go for it 2 FW ports, and USB ain't great for audio streaming with multiple channels.

USB or FIREWIRE for audio interface?

Hi,
what will you prefer to , USB or FireWire of your audio interface?
and why?

Here's the "pecking order" for performance and stability :
1.- Internal PCI or PCIe card to audio interface. These units are the best overall, both in audio quality, low latency, and reliability. Some have built in processing cards, with which you can use instead of the computer's CPU, for audio processing tasks.
2.- FireWire audio interface. These are reliable, but can have issues if not set up properly, due to the FireWire drivers which need to be used to run these units. Some have onboard "low latency" mixing facilities, and some have CPU processors for processing audio.
3.- USB 2.0 audio interface. These are also reliable, however are more limited in bandwidth than the FireWire counterparts. This is due to the different nature of the USB audio protocol VS the FIreWire one. Still, it is not that bad for home recording.
4.- USB 1.0 and 1.1 audio interfaces. These are reliable, but not recommended if a lot of realtime audio recording is going to take place. In other words they are great inexpensive units for doing programming, sequencing, editing and mixing, BUT not so much for live audio use, or live audio recording. this is due to the limitations on the USB audio protocol architecture. It simply cannot handle low latency audio very well.

Won't recognize firewire for audio interface

I am trying to run a Focusrite Saffire Pro 14 through the firewire port on my brand new Macbook Pro, only problem is that the computer is not recognizing the device. I've been at this for a really long time now and I havent the slightest clue on how to handle this. Any feedback will be much appreciated.

Hi Tom,
I'm using a MAC Book Pro OS X version 10.5.8 with a Sony HDV 1080i/mini DV. I have them connected through a 800 firewire. I'm trying to import onto Final Cut Express 4 that I just downloaded yesterday. Quick time version 7.6.9.

No power from Fire Wire port to my audio interface

I face this problem after my set-up always has worked: I have a Quata Fire 610 Audio interface, powered thru my Fire wire 400. For some reason there is no power, and my Mac does not recognize the unit. I have tried both Fire Wire ports, and none of them works. The unit works fine on my other Mac (iMac G4) Is there any way I solve this problem. I have done the the disc utilities.

FireWire ports have been known to fail.
Did you shut down (power OFF) the Power Mac G5, and restart? Did you also try the port on the front panel? Did you try a different FireWire cable? Is it possible to try another FireWire device on the ports, as a test?
You can also try a reset of the PMU or SMU (power management). Depending on your model

IMac FireWire port used for USB device

I have a 27" iMac which of course has a FireWire port, but I don't own any external FireWire devices. I'd like to put that empty port to use as a USB port to connect an external storage device. Is there a cable, converter, or adapter made to do that?

Common user always looks at the bottom line price on computer peripherals and USB devices are always cheaper. USB 2.0, in theory, should be faster than FireWire 400, but they usually aren't because of the way USB transfers data in short bursts or packets of data. FireWire 400 and 800 drives are faster as they transmit data in a more continuous, constant and reliable stream of data.
This is why devices that use FireWire or have both USB and FireWire connections are always more expensive.
So, those users never use the FireWire port.
FireWire is faster for external hard drives, especially data transfers and for booting and running a Mac from an external FireWire drive. FireWire optical drives are faster. FireWire audio devices and interface devices are even faster and more reliable than USB.
FireWire is more expensive, but more reliable data transfer protocol.
There is no way to bridge the two device protocols . It's either one or the other. The masses always choose the cheaper USB devices.
The masses don't care about faster and consistent data transfer rates or better reliability.
Especially if a user isn't some sort of creative like a graphics, designer, Illustrator, photographer, digital painer/3D-CGI Artist, engineer, audio or video/multimedia professional.

Help needed for audio interface!

Hello, i am trying to set up a small recording studio at home. i have short listed o2 audio interfaces but unable to decide which one to buy? one is Tascam US-144MKII USB Audio Interface and the other one is Focusrite Scarlet 2i2, if you guys can help me choosing the right one.
my main use would be covering songs and recording vocals and instruments at the same time.

Oh I get that... we all have to work within what we can afford.. and you are not the only one who budgets like that for sure.. but here's the thing..
Note: What follows is just a personal opinion. based on my own personal experienes and those I have worked with here and elsewhere.
You are using a $1000-$2000+ Mac... an App worth $200+ plus extra for whatever 3rd party plugins you have bought.. extra bucks for a Midi controller...and yet you are only willing/able to spend $125+ on a combined Audio/Midi inteface?
It's kind of like buying a $100K Ferrari and then putting $50 tires on it..... and expecting to get the best or even just average performance from your car? It simply doesn't work that way in reality..... and trying to make such a low budget for an Audio / Midi interface.. will only lead to possible issues in the future....
There is a good reason why it tends to be the same audio/midi interfaces which are owned by people who also report issues with the current OS X version and/or Logic .. The cheaper products simply aren't so well supported or designed/developed as the more expensive ones... and so thats what happens...
Look at the current issues going on with Mavericks for example..
Mackie/M-Audio/Avid/Digidesign/Tascam are all having driver/hardware issues of one kind or another..to differing degrees..with various products they sell.. with little sign they are close to properly fixing things.. Focusrite are, at least, working hard with Apple to resolve their driver issues...but currently they are having some issues with certain products in their range too.. The cheapo Midi-USB2 cable type interfaces that sells for $20-$40 are all non starters/buggy as heck.. when used with ML/Mav and/or USB3 ports.. and most of these cheap products have the exact same issues every time OSX undergoes a major update! Sometimes they are fixed eventually and some times they aren't. In some cases the companies simply release a new replacement product leaving owners of the older versions.. left to their own devices.. (sic) and without any recourse or solution.. other than to buy a replacement or not being able to upgrade their Software/OS X
So... here is what i would suggest...
I'd rather buy a used Motu (or one of the other brands out there that are known to be reliable) for a couple of hundred bucks or so.. on eBay than buy a new cheaper interface.... but of course the choice/decision is yours.

Recommendations for audio interface with new mac pro to avoid latency?

Hi friends,
I have a new Mac Pro on order for editing video in FCPX, but Presonus says my older Presonus Firebox won't work with Mavericks and the new Mac Pro. Do you have a recommendation for a replacement?
I only use the interface to drive 2 powered expternal speakers and a headset, so I don't need something super sophisticated.
As I read about units, almost all come with USB 2.0 connections. But the new Mac Pro only offers USB, Thunderbolt 2, Dual Gigabit Ethernet, and HDMI 1.4 Ultra HD inputs. If I can't find a fairly inexpensive audio interface with USB 3.0, I'd have to go through another connection to get into the Mac Pro.
The key for me is to make sure and avoid latency, a critical issue for editing video.
Any advice is much appreciated. Thanks. Duncan

Thanks Mark and Smokerz,
Your point about USB2 working in USB3 ports is something I wasn't aware of. That opens a lot of doors for me. And I'll look into the Yamaha sound board as one possibility.
Thank you both for helping me.

Cheapo alternative to Apple Lightning to USB Camera Adapter for audio interface?

I am getting an audio interface (Steinberg UR44) which can be controlled with an iPad via the Apple Lightning USB Camera Adapter and a standard USB printer cable (Type A male to type B male), but I am too cheap to buy the ridiculously overpriced Apple adapter, so I am wondering if the following will work instead:
iPad --> Apple lighting male to USB Type A male cable (the standard charging cable) --> USB Type A female to Type B male adapter --> Audio Interface
Other adapters are available for USB Type A female to Type B micro or mini male, so the same kind of arrangement might work for cameras.
The adapters are five bucks or less vs. thirty for the RIDICULOUSLY OVERPRICED (yes, I know, I already said that) Apple adapter.
I am thinking this is a better way to go than a cheap unlicensed knockoff lightning adapter, because the critical part of the connection (the lightning plug and electronics) would still be made by Apple.
Has anyone tried the above with either an audio interface or camera?

Because it was designed for use with the iPad. Apple makes no claim that it will work with an iPhone.

Additional firewire port needed for Canopus

I have always used a Canopus to change analog video as I download onto my Mac G5 for video editing in iMovie. I recently replaced one that quit on me and now new one is not working right. Both analog and digital lights stay on, rather than one or the other depending on my need. I took it back and exchanged thinking it was broken. The second one did the same thing. Apple store said to try the firewire in the back of the tower as front one may not be working. I do not have one in the back that is not in use. Anyone have any advice?

You could try using a firewire hub like [this one|http://www.amazon.com/gp/product/B0006BHCEK].
Capturing video using a hub is not really recommended, but at least you would be able to leave everything connected, and do some troubleshooting.

Suggestions for Firewire port allocation for DAW

Hi all,
I'm wondering if I've got my rig set up the way it should be. Specifically I'm talking about how / where is the best way to hook up my Apogee Ensemble & external FW drive. My understanding is that my machine (PPC G5 Dual 2.3) has one FW 800 port on the front and two FW400 ports on the rear (one with a different type of connection than the other). Should I put both the Apogee and my external HD (that I use with Logic projects) on the 800 port? Should one go on the 400 in the rear? What would be the best set up?
Thanks in advance!
Mark

Hi Mark,
You have your 400/800 mixed up...
Your G5 has two Firewire "400" ports (one on the front and one on the back), and one Firewire "800" port on the back.
FW800 port...
FW400 port...
Do you have a FW800 Drive, then that'd likely gain the most from the FW8oo port.

Usb ports and FW ports not supporting audio interfaces

Peace! I have recently ran into a situation with a fire wire interface and usb interface, where neither one will stay powered for a long time. Now its to the point where my macbook, doesn't recognize them at all. I have re-installed drivers, erased the drive, and re-installed the OS. I have also reset the SMC and PRAM, nothing seems to be working. If anyone has any information it would be greatly appreciated as this is frustrating for me at the moment. Thanks in advance! Peace!

iMac 21.5-inch, Mid 2011(OX 10.8.5).
I call the repair shop and they told me it would coast $2000 to get it fix, they told me that my mother board was burn, so I send them an email telling them if my mother board was burn wouldnt be able to use my imac. I could get a new one for that price.

Firewire chain for external audio interface and hard drive

I use Logic Studio 8 on a Macbook Pro with a Presonus Firebox, an external Lacie Firewire hard drive for audio recording, and another Lacie Firewire drive for backups.
Is there a recommended chain order when chaining my Firewire devices together? I read somewhere on a ProTools forum that they recommend putting their Firewire audio interface Mbox2Pro at the end of the chain.
So right now I have Macbook Pro -> Backup Drive -> Audio Drive -> Presonus Firebox. I once had it in a different order with the audio drive first, but I found it was reading more slowly from/to the audio drive when it was in that order. I have no idea technologically why this would be the case.

I just found and joined this great forum. Following up on Ray's comments about his MacBook set-up, I have a similar MacBook 2ghz, 4mb ram, 9400 chipset, and am exploring getting into Logic Pro 8 and was wondering if my MacBook was underpowered, and whether I needed to step up right away to a MacBook Pro because of my lack of PCI slots for recording audio to an external eSATA drive.
I was encouraged to hear that the USB 2.0 connection for Ray's external WD 7200 hard drive has worked and improved things and his audio isn't getting choked and he is not getting the clicks and other problems.
I'm wondering if Ray or anyone else has any other tips on using a MacBook for Logic and for optimizing one's setup. And Ray, did you notice a point at which the clicks started? .. in terms of number of tracks? Or were they present from the outset? I'm wondering how many tracks you are running now on your system.
I might mention that I don't have an audio interface yet but was impressed with what I've read about the Apogee Duet. Any comments on interfaces and the Duet?
By the way, I'm just recording one instrument/one track at a time and perhaps occasionally two instruments at a time. And right now, my main purpose for getting into Logic is for editing and mixdown of pre-existing tracks that have already been created on a standalone hard-disc based DAW. If all goes well and if I like the whole Logic experience I'd expect to get a more powerful MacBook Pro or even a Mac Pro or whatever higher end iMac exists in the future.
To summarize, all I'm intending to do initially with the MacBook is:
1) transfer individual digital tracks from a standalone hard disc-based DAW into Logic for mixdown and mastering.
2) Record a few extra new tracks one at a time - probably not using any instrument plug-ins but relying on external synth/sampler/guitar sound sources ..in each song (maybe 3-4 tracks at most), and
3) apply standard effects like reverb and EQ and panning to the mix down and master songs, each song containing a of approx 25-40 tracks.
My basic question is, can a MacBook 2Ghz with firewire 400, 4gb memory and USB2.0 to external hard drive handle this or is it underpowered? Thanks.

IMac20" with firewire audio-interface konnekt24D by tcelectronic

Hi folks,
I've got some cryptic problems with my iMac and the connected firewire audio-interface (konnekt24D by tcelectronic). I'm running MacOSX 10.4.10. The problem is that after four days working with no occuring problems I got no sound output. When I restarted the Mac the blue firewire light of the audio-interface disappeared and the tcnear control panel says 'no device'. I decided to update the firmware and then everything runs properly for one day. The next day I got the same 'no output' problem. I decided to update the firmware again but now the blue firewire light disappears and I got 'no device' message from the tcnear control panel. I started the Mac again but the interface was still gone. Now I switched off the Mac and turned it on again. The interface was there and I had output. Next day I got the same problems.
The tcelectronic support said that I should disconnect any other network cables, enable every network setting on the network control panel and connect the power supply of the audio interface. I did everything but got no improvements. The people from tcelectronic concluded that my audio-interface could be defective. So I went to my mönger and he gave me a new one.
From now on everything worked fine for three days. During this time I changed nothing on my setup. No new software was installed, the only thing I did was to start LogicExpress 7.2.1 and begin with my work. After three days I got the same 'no output' problem again. Now I think that there must be something wrong with the iMac. It is the 'old' version (bought in May this year) and I don't know exactly what to do now.
What I don't understand is that both devices worked a few days and then the problems occured. As I said before I didn't changed anything, installed no new software, etc. Maybe the harddisk of the iMac is defective? I've plugged the audio-interface into the other firewire port of the Mac but got no improvement.
I don't know exactly what I should do know because I worked ten years with a PowerMac/Audiomedia III/SCSI system and never had such strange problems.
Greetings to all of you,
Dorsch.

It appears that sp3 has issues with firewire. I'm seeking a solution too, short of reinstalling as this person suggests. See also his link re: the famous little patch. I tried that already to no avail. I'm using SP3 too. My firewire behaves like USB... which would/could cause issues like you're describing.
