Hello everyone,

A while back i purchased a Yamaha Motif XF6 (A synth Workstation), and i connected this device to my P6T Motherboard Firewire slot. 6 pin <-> 6 pin.
Also, my KRK's are connected to the back of the Motif XF6.

Everything works fine UNTIL i plugin the Firewire connector from the PC to the Motif to Record.

It starts to make a very high Frequency Whisle/Noise/Beep. Its not VERY loud, but it gets VERY annoying after a few minutes.

Here's some things i tried to fix this problem:
-Plugged the AC Plugs in other boxes
-Played around with the cables to see if the signal got better (no)
-Got a PCI Firewire card, didn't work.
-Got a better isolating Firewire cable - Didn't work.

I THINK it has to do with the fact there's already a AC plug running to the Motif, and with the 6-pin FW plug (which also delivers some electricity) they kinda crash into eachother somehow.

... I hope you clearly understand my problem, else ill be happy to clearify some things.

Thanks in advance Everyone!

Robert.

Is the whistle a continuous pure tone or does it change in character or intensity as you perform different actions in the computer?

Does the Motif run when just powered through the FireWire cable? If so, do you get the whistle when configured like this?

TheJackAttack: This sound is also around without any programs started up, though, i did try to change the sample rate, the whistle does change, but doesn't go away.

Bosswell: It does kind of change, also - What i noticed is that it reacts to my Harddrive, when something loads up - The whistle also stops.
The Motif isn't able to run without the main AC Adapter

Thanks!

Unless you can do some swapping around, this is going to be tricky to diagnose, and there is not necessarily a complete solution.

You should try to borrow another FireWire-equippped computer and plug your Motif into that. See if the whistle is still there, of the same intensity and comes and goes with disk activity similar to the way in which your own PC behaves. It could well be that you get a different noise with another computer, maybe less, maybe worse than with your own.

There are ways of isolating FireWire connections to reduce this type of effect, but none of them are particularly cheap. It may in the end come down to accepting that there are some combinations of gear at this level that give background problems, and spending money to re-engineer the setup is the only way to work round them.

Sorry not to sound more positive, but one reason that pro studio gear costs what is does is that it is designed and built so you can (usually) plug one piece into another without encountering this type of problem.

I don't think it's a grounding problem as such. It may be a power noise problem, in that it might improve if you were to use a 6-pin to 4-pin FireWire cable and go through a 4-pin FireWire adaptor at the computer end so that no computer d.c. power went down the cable.

A DI box is not going to help.

In my previous post I suggested trying a different computer.

mdb Thu, 02/03/2011 - 09:08

Plug your computer/screen and all your hardware into the same outlet on a power bar or power conditioner. Unplug your printer and any firewire external drives or other devices. I had the same problem with a Firebox and could hear the mouse movement on the screen as well as my HD through the speakers. I put EVERYTHING onto the same outlet and it went away. It's probably a ground loop. If you are able to run a dedicated plug from your panel do it.

Boswell Thu, 02/03/2011 - 09:09

That's why I mentioned a 4-pin adaptor. You can get these for digital cameras and the like that come with a 4-pin cable and people need to plug them into 6-pin FW sockets.

Even another desktop PC you could transfer your PCI FireWire card to would give some information, but I think the 4-pin FW trial is liable to be more rewarding.

Don't be discouraged. These are often the sort of problems that you have to nibble away at over a period of time as and when you get the opportunity and the chance of exchange equipment. In your case the whistle may be annoying during monitoring and mixing but at least it should not be captured in your recordings.

Unheard Thu, 02/03/2011 - 10:18

Thanks for the replies :)

I found a 6 to 4 pin converter, and i found a FW PCI card WITH a 4 pin slot.

Unfortunatly ... doesn't work. As soon as i plugged it in the very high peep came in again .....

Gonna try to plug everything into the same box now!

And yeah ... and really cant work with this annoying peep.... gets on my nerves after 20 minutes :(

Unheard Sat, 02/05/2011 - 03:35

So i contacted Yamaha....

He's asking me if my power supply gives enough Volts, and concludes something is ****ing it up in the setup.

Also, he keeps on HINTING me on getting a Texas Instruments Chipset. Because this is the most compatible with the Motif.

The hell does he want me to do, buy a new Motherboard???

This is really frustrating.

mdb Sat, 02/05/2011 - 09:58

Try SiiG. It's been an excellent card for me. Mine is a 4-port and I don't see one on their site anymore, but here's a link...

[[url=http://[/URL]="http://www.siig.com…"]SiiG Firewire 400 PCIe cards[/]="http://www.siig.com…"]SiiG Firewire 400 PCIe cards[/]

I'd be surprised if that fixes your problem, but possible. Regardless you'll be happy with the card.
Lame to spend money on a potential fix if it doesn't cure the disease.

Unheard Sat, 02/05/2011 - 10:29

Yeah i agree.

Thanks for the link, looks like a excellent card!

I'll put it on for my favorites, and ill wait until i get a new Yamaha Answer.

Because i would find it kinda strange if this would fix the problem. Because the slot of my Motherboard gave the exact same beep as when i put it into the Firewire PCI card. The signal didn't become less or more.

It WAS a cheap Firewire card... but still.

TheJackAttack Sat, 02/05/2011 - 13:40

Not all firewire chips conform to the IEEE 1394 standard despite being labeled firewire. Cheap chips have been an issue with audio video editing since the start of firewire. Your mobo onboard chip is not likely TI either but most motherboard manu list what it is somewhere. In the past several years not all SiiG cards have TI chips either so just double check at the SiiG website first.

I've had this problem. Having a RME FireFace 400 I found out that it was super-finicky about what type of Firewire cable will work with it. I'd suggest the clear "braided" Firewire cable (which was supplied with the unit). Any other Firewire cable had the high-piched whine.

Unheard Sat, 02/05/2011 - 15:02

Something like this?:

Features:
- HotPluggable.
- Twisted pair construction for extreme velocity data transfer rates.
- Molded strain relief and PVC overmolding to ensure a lifetime of error-free data transmissions.
- Outer shield and inner shield (foil and braid) ensures compliance with the latest IEEE 1394 standards, which reduces radio frequency and electro-magnetic interference.

You able to look up the type nr./model of this cable? Never really heard of the word "Braided".

Thanks!!

Here's a link that shows what a braided cable looks like:

I guess this is what your talking about? I'll order it, with a TI PCIE card

Did you see the cable at the site? I had to re-post the link.

Slight update:

Got a reply from Yamaha: They are telling me to try putting all plugs into the same box, which was also suggested here. - I tried this, didn't work.

Their second suggestion: DI-Boxes. - Im gonna try this if my new cable and fw pci-e card doesn't work..

I was wondering though - just in advance, what DI-box isn't too expensive, and does what it needs to do just fine?

Thanks.

Boswell Mon, 02/07/2011 - 10:06

Exactly how is a DI box going to solve this problem? A DI box takes an instrument-level high-impedance analog signal and generates a low-level microphone-level balanced signal, whereas your trouble with the Motif is the digital FireWire input modulation breaking through to the analog output.

[="http://www.thefreelibrary.com/_/print/PrintArticle.aspx?id=57778456"]Here[/]="http://www.thefreel…"]Here[/] is an article about FireWire ground noise, recommending capacitative isolation, and [[url=http://="http://www.powerdes…"]this[/]="http://www.powerdes…"]this[/] is another article about isolating FireWire. If your trouble is indeed due to audio-bandwidth digital currents circulating in the ground loop, then the sort of techniques outlined in the articles should help. A TI [[url=http://[/URL]="http://www.ti.com/s…"]set of slides[/]="http://www.ti.com/s…"]set of slides[/] goes into some of the isolation problems with FireWire. However, if the problem is in fact poor isolation of the digital signals within the Motif, then nothing external is going to help you very much.

I hope your new cable and FireWire card reduce the problem to an acceptable level, but I have my doubts...

mdb Mon, 02/07/2011 - 10:17

A DI isn't going to be of any use. A DI box is to go between Hi-Z input devices and the Mic input of a mixer/ preamp. The added benefit of a DI with a ground lift is to break the ground connection between two powered devices (e.g., keyboard & mixer) to eliminate ground loop hum. Although you should probably have a DI in your arsenal anyway for live sound situations or if you do connect to a board some day, if you are getting noise without anything plugged into preamps, it's not going to fix your problem. You're connecting direct with Firewire, no? Sounds like Yamaha is trying to deflect blame in case something is wrong with your Motif.

What do you consider cheap? Art and CBI make really cheap stuff. Radial is the best IMHO and have a decent DI for $79 called a Radial Pro. The Radial JDI as awsome, but $180 'ish. If you can afford it you'll never be dissapointed with a Radial DI of any kind. The really cheap stuff may give you crap sound.

Boswell, you beat me to it. I type too slow :frown:

I hate to spring pricy suggestions that may or may not work but sometime down the line you might consider a power conditioner for your equipment as mdb mentioned. It would "put all your plugs into the box" while (hopefully) eliminating ac ground loops while adjusting current flow. Here's yet another link:

Very important to choose the right one here, many are big on claims & short on performing (even some of the big name brands). May want to read the reviews on this one.

Once again, not promoting a website. Perhaps someone can recommend a power conditioner where you are that makes the grade.

So......

got a braided cable, and a TI pcie card.. DIDN"T WORK ....... Getting depressed. Wasting money this way.

Anyways..... Can it be a Software problem? Because the beep only starts if the Motif program fully loaded, and the sound changes when i screw around with the Sample rate..

When i get home ill also plugin headphones. see if the sound comes through the headphones

mdb Wed, 02/09/2011 - 08:28

What type of lighting do you have? If the room lights (especially with dimmers or florescent light ballasts) are on the same electrical circuit, they can cause noise in an audio system. Turn the lights off in the room and anywhere else they are on the same circuit. Doubt it will help, but it can't hurt to try.

Is there an analog output on the Motif that you can try to connect to the computer with? If it's ground loop you should still get the noise through that as well. Otherwise, I'm thinking it's the Firewire card or some other circuitry within the Motif. Do you have access to another Firewire keyboard you could test on your setup?

Boswell Wed, 02/09/2011 - 09:06

I see you posted the same problem on the Yamaha Motifator board, and that's maybe where you picked up the erroneous idea of a DI box to solve it. What you should take away from that board is that you are not the only Motif owner with this problem, and that in my mind indicates the source of the FireWire breakthough trouble being internal to the Motif.

While there are things that contributors to this forum can suggest you try, my guess is that external palliatives will only modify the amount of high-frequency breakthrough and not eliminate it. It could be that you and other afflicted Motif owners should raise the level of concern directly with Yamaha, as it appeared from the Motifator board that the manufacturers were not taking the problem sufficiently seriously.

I have tried it, but just for my Room - I didn't shut down the other lights of the other rooms. I'll def. give it a try though!!

There is a Analog output, ill have to try to find a cable though. I can also try a USB cable, see what that does.

I tried several Firewire Cables, cards, and the Onboard Firewire Slots, and the "beep" is the same on any combination. So i think the problem isn't laying here ... ? :confused:

Thanks mate.

-Yeah, i did - And yeah, they suggested a DI box.... As they suggested a whole bunch of %(@*&.
I kind of gave up that forum, also noticed the main Yamaha Moderators stopped helping me out. Afterwards i contacted Yamaha themselfs and they ALSO suggested a whole bunch of stuff, and also a DI Box .... But why would it even work if the other 9 things they suggested ALSO didn't work out......

And yes, i get the idea they are putting the problem on my other equipment, even though there's numerous of others having the exact same problem as i am having.

I totally agree. But i am still hoping for just a simple answer so i can just MAKE MUSIC .... haha. I am gonna try a few more simple things, and else ill return the Firewire Expansion, and get a SP/DIF cable + Usb cable for midi.

I think its total BS..... This problem that is.

Thanks mate.

I wasn't too clear. I was referring to the firewire card/circuit inside the Motif rather than your PC. I'm beginning to think it's the Motif.
