Clicking and Popping

I know what you are probably thinking, but its probably not what you think it is.

I have a Digi 002r and a Presonus Digimax FS. I connect them via Lightpipe. For some weird reason I get occasional clicks and pops. Now the biggest problem with that, is that I get it on my channels 1-4. (Digi002r). Thing is, I only get the clicks and pops ONLY when the Digimax FS is connected. (all the digimax channels are fine and don't pop).

When the digimax is disconnected, and I just use the 4 channels on the 002, I get no pops and clicks.

Does anyone have any thoughts or ideas of what could be a possible fix?

I know its a problem with the digimax, because I tried mine and my friends. I got the same results.

Thank you.

Any idea on how I go about fixing that?
I'm afraid not, I don't have either unit.

You could open the driver control panel and see what's clocking what. If you can't figure it out from that, check the manuals.

My guess is they are both trying to be the master.
If you are using protools, open up your Session Settings page and set clock to ADAT. Then your Digimax will be the master. Just make sure it is set to the same sample rate as your session.

I am having a similar problem with my iMac / Logic 8 and Apogee Ensemble. Being a new to this stuff, i am not how to determine who clocks what. Does anybody know how to fix this in Logic?

I am actually using Logic 8. (also using iMac) Here are the specs, just so everyone knows. iMac 2.4 Ghz C2D, 3GB ram.

I use the Digidesign Core Audio manager... Is there anything I can change in the digidesign manager?

I believe your problem is because you set your buffer size too low. Tell me how much ram you have. if you have over 2GB buffer size of 256 should be fine. Maybe even lower.

We had that issue with Sonar.......

Solved by turning off all wireless connections.

I would guess a clocking problem as suggested. However, I don't see that the O2r will sync to word clock, otherwise the FS could be the master.

You'll have to learn how the clocking functions work on both units to ensure that's not the problem--one should be slaved to the other. I don't own either, so I can't help there.

Sometimes driver updates address these types of issues--make sure you've got the best ones for each device.

I solved random noise problems by disabling my wireless NIC. It was sharing an IRQ with something else that was causing a conflict which resulted in pops and such. Give it a try, it might help

Thanks everyone for your help. This whole week has been a frustrating one, with the clicking ruining my sessions. BUT i found the solution. Its kind of irritating that I didn't think of it in the first place

The problem was.. my 002 and the Digimax FS were clocked correctly (Digi002 was syncing through Optical>Adat and my FS was the Syncing Internally). The problem was logic. It wasn't set to auto sync, so it was trying to be a master along with the FS. After checking the checkbox for Logic to Auto Sync, all the clicking is gone.

I am no longer considering of selling me 002 :). Thank you.
