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.

Ahhh, got it.. Hmm, you think it's a option to take the card out, and put it in again? maybe its not in the slot for 100% or something?

Also wondering if it's MAYBE something Software related ..

When i boot up the PC, i hear no Beep except for some very little noise which is normal with my active speakers.

As soon as the Sounddriver boots up, the BEEEEEEEEEEEP starts .. When i screw around with the samplerate, the
Beep also changes, it gets thinner, or worse.

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

Man, i'm sorry to hear that cable didn't work. Is it the same type as the one from the link? Is it clear? Can you see that it's braided? Trust me, all cables are not created equal. I have a Motif also, an older one an ES6. I have the Firewire card for it but I can't use it because Yamaha dosen't make Win7 drivers for it, so i feel your pain. The suggestion for trying another PC that has Firewire is a valid one. If you have an entry level PC it may not be capable of managing FW, even if it does have a FW port. Some of the lower budget cpu's just wont cut it. Quality componets & construction are crucial if you're using your PC for DAW purposes .

UPDATE!!! ... Kinda

I noticed the sound comes from my COMPUTER ... i guess my processor or something - I pulled the Firewire cable out, and the sound got WAY less, but i can still hear the exact same whiney sound.

So this sound gets put over to the monitor speakers when i plug everything in....

So what the hell is this sound then?!?!?

Good find. I had to read up on the C1E to find out what it is and what it does. Puts the CPU into a low voltage, Hi-Z state to save on power consumption. I wonder why it was causing that noise? I would have never figured that out... well done!!

You've got some nice new hardware out of it too. :wink:

Hahahaha,

My girl was like: SO... Did this stuff finally solve your problem?? *Looks at the new cables+PCI-E Card*

Me: ... Huh? Uh.. Yeah sure did!

Yeah, i noticed the Beep persisted when i shut down my speakers, i thought it was echo'ing in my head or something, hehe. But when i heard it coming from the PC i layed it open, and i noticed it was the CPU

Wait a minute. You're saying the sound was not coming from any speakers but somehow emitted by the CPU itself? Crazy!!

Well, come to think of it, maybe the low-power mode was causing the CPU fan to spin at a non-optimal rate and produce a squeal. I've had a fan go bad on a GPU that was VERY loud.
