Question

I have 2 Quantum daisy chain and aggregated in Mac OS as per Manual. One is set as master clock (internal) and the other using a BNC as Wordclock. My issue is that every time I turn on again the computer in the next session they both appear configured as internal and have to do it every time. When both are set as internal I can ear some static noise (like an old record) in my Studio One recording. Any help?

Answer 1

This was happening (wordclock preference resetting) for me too until recently. Not sure what changed, I didn’t update UC or anything, just randomly started remembering it again.

Answer 2

Mine is the same, I have to set it each time, then go into Audio/Midi settings and uncheck, then re-check the Aggregate Device "Drift Correction" every time or else I get clicks.

Answer 3

Same problem here, but with 3 Quantum interfaces daisy chainned.
Thing is, my Mac has not come to the point of saving clock preferences, like robertgray3 says. So, each time I reboot, the clock configurations in all 3 Quantum are reset and shows "Internal" in all 3 of them.

Answer 4

Please everyone having this problem open a ticket with support. I'm almost in a fight with them since they are questioning is only my problem and on my Mac (not true becouse I follow all their suggestions to create new profile, reinstall and even tried with another Mac. Problem is still there.)

They tried 2 times already to close my ticket that I always reopened but.still they don't want recognize is their fault.

Answer 5

I've just oppened a ticket on Presonus.
Until now, I don't have any anything to say about their Support. They have been a tremendous help in all my cases.
So, let's see what they will come up to. Maybe it is a Mojave thing or some firmware versions issues in some equipments.

Answer 6

They have been very good and smart on everything related to mixer and other audio. This seems a different people /group or maybe just my bad experience I. This case. I believe they do not realize how much annoying and risky is this (If you forget to set back every reboot than recording is jeopardized)

Answer 7

Yeah, it is annoying, the clicks are the worst.  Even changing screens when audio is playing causes a momentary click/silence in audio.  Changing buffer sizes can cause the clicks also.  Focusrite had the best way, I never had clicks when using them, but you could daisy chain 2 Saffires, I had the Pro56 and the 28, both connected via Firewire, but was seen as only 1 device, no need for aggregate set ups, which I think is the whole cause of this, that and it seems when an application wants access to the audio interface, momentarily, all audio inputs are open...total guess, but their shouldn't be clicks due to screen redraws/changes.

I think Apple OS has something to do with it also, but using word clock, ticking or unticking Drift Correction, it all fails at some point.  Personally, I've spent too much time trying to sort this by unplugging everything, re-installing, going into apple plists and deleting things etc.  it's clearly flawed.

Answer 8

Any  news on the subject? Got the same problem with 1 Quantum and the Apogee rosetta.

Answer 9

This problem is still pending and support seems not able to fix since they said cannot reproduce. I tried many ways, new profile, other computer..but still there after more then one year

Answer 10

I have the same problem with a Quantum 1/Quantum 4848 combo. The 4848 is clocked from the Quantum 1 and it resets to Internal each and every reboot.

Answer 11

I'm having the same problem as everyone else.. my quantum is daisy chained to a 4848 and every time I reboot the clock source on the 4848 switches to "Internal" instead of "BNC wordclock." Looks like this problem has been happening for over a year and I didn't read about any resolutions to the issue on this thread. Has anyone found a workaround or is there a moderator from Presonus on here that can chime in?

Answer 12

This is totally annoying and is even more annoying that not only they dismissed the tickets not nobody is taking care despite a large number of users reporting the issue. Is a very simple fix, just to save the configuration in an xml file.

Answer 13

I noticed this not happening if the quantum are powered even when off. Since in my studio I shut down the power for the nighg (is not in the house) this keep resetitng the preference. So seems a problem of this setting not being saved in the permanent memory or at least a problem with battery that should keep eeprom memory. Maybe someone will investigate one day since it seems we are many with this problem!!!!

Answer 14

I got threatened by prespnus to disable my account because I swore at them about the 4848 and it not working.

to hell with this company...

Recognize that the 4848 has issues and either fix it or refund us.

I think we should all get a class action going.

We all paid good money for these things. and Presonus just sits on their *** on this issue.

Answer 15

The situation is even more terrible now. After the last UC upgrade, is not just forget at any reboot, but is now impossible to set the external clock (UC just revert immediately) to internal and support responded only to contact "a local technicians", but they have none in Italy (and I'm an IT person too) !!!!
