paca<->TC Konnekt24<->ADAT<->Saffire Pro40<->mac
the clock source is Saffire Pro 40 and send his clock signal over ADAT. I'm on OS 10.10.5

How are you running TC Near on your Mac? Are you installing the TC driver bundle whenever you need to run TC Near, and then uninstalling when you are finish? I ask because the TC Konnekt's FireWire drivers cannot be installed on your Mac if you wish to use it as the Pacarana's sound card.

Also, just an FYI, most of the Kyma user community activity has migrated over to the new Kyma user site. These sorts of questions are now being handled in the Q&A section (http://kyma.symbolicsound.com/qa/), which IMHO is an excellent way to do it. It might make sense to ask your question there so you can reach a bigger audience.

Regardless I'll look for your reply here and try to help as best I can. I use a TC Konnekt 48 with the Pacarana and also sync it from the Mac's Saffire Pro 24 DSP soundcard. So our set ups are similar.

Yes, I install TC Near when I need to reconfigurate TC Konnekt24D and after that I uninstall it. But unfortunately it changes the sample rate automatically after some playing with Kyma 7.

You are everywhere for helping Kyma users, isn't it? Thanks!

I thought this specific technical issue is better to place it here in the good old forum. If I understand correctly for every question is it better to ask in Kymas Q/A area?

That's probably a better question for Symbolic Sound. What I have observed though is that the traffic on this forum has been dramatically reduced since the new Kyma 7 community was highlighted in the Eight Nerve issue before Christmas. This forum is also a little harder to find things. But the real reason I mentioned it was that it seems things are moving away from here, and the activity, at least on the Q&A, seems more robust.

Anyway back to your problem. What I see with my TC Konnekt is that I can set the sample rate from the Kyma DSP status panel as needed, provided I also set the same rate in the Saffire, which is the clock master in my case. The Saffire's sample rate though is normally set by whatever audio software (like a DAW) I might have running along side Kyma. So I've been caught out a few times with mismatched sample rates.

One thing you might want to check in your TC's configuration is what sample rate is assigned to the active configuration. The TC48 can store 3 different configurations, any of which can be recalled from its remote. But it remembers the last one across power cycles.

Pure speculation here, but maybe what is happening is that the TC is not able to sync so it is falling back to configuration sample rate. Have you verified that you still have a working optical connection from the Saffire to the TC?

Another thought. The TC48, and maybe yours, has a stand alone mode and a corresponding configuration for clocking. The stand alone mode is only supposed to "kick in" if there is nothing controlling it over FireWire. Perhaps you have something happening on your FireWire bus that is causing bus resets, which in turns causes the TC to drop into stand-alone mode briefly, enough time for the sample rate to change.

I have in the past seen problems with unexpected FireWire bus resets. Maybe check your FireWire cables, and if you have other FireWire devices connected try taking them off line for a while.

Your Mac has but a single FireWire bus that is shared with all of the FW400 and FW800 connectors. So any devices connected to those can potentially affect the FireWire bus.

Finally, as a test, try changing the clock master from your Saffire to the TC. I just recently used that configuration and it worked fine. You can set the desired sample rate from Kyma. Its a little fiddly if you do a lot of work with Kyma off; you'd have to manually switch the Saffire back to internal sync. But its a way to see if that changes the behavior, and maybe even a temporary work around.

at the time I'm trying the configuration in which TC Konnekt is the Clock Master.

I can switch to a different sample rate and Clock source In Kymas DSP Status but it doesn't have an effect on TC Konnekts setting.

This is different from how my TC48 is operating. I can control its clock source and sample rate from Kyma. I believe that is the expected behavior. After all Kyma, through the Pacarana, is acting much like a DAW host. And from within a DAW you would be able to select the soundcard's clock source and sample rate. So clearly something is preventing your set up from operating in the expected manner.

I operate my system at either 44.1 or 48. The higher sample rates change the behavior of the TC's and Saffire's ADAT ports so I have not used those sampling rates, at least not in the recent past. I just did an experiment trying it at 96kHz. I could not get it to work properly. Probably an unrelated issue and I did not troubleshoot further.

But what I noticed is that when I attempted to return the sample rate to 44.1 or 48 the TC48 was no longer locking (there's an indicator on the TC48's panel to show this). Nothing I could do could affect it. It was as if Kyma no longer could control it!

I did a Reinitialize command from the DSP menu and everything returned to normal. I probably could of achieved the same by power cycling the TC48 but that is only a guess.

I have no idea if any of this is related to what is happening to you but I wanted to pass it on.
