OS7 Public Beta Discussion

  • JSB the point isn’t whether or not you are able to do it just now. If you say that you have it working without any clicks and pops I have no reason to doubt you. However, the technical spec (according to CK himself) is not capable of doing this robustly due to hardware limitations. With most things in life it is possible for unlikely and unexpected event to occur by chance on occasion. However, that doesn’t mean the can be recreated at will or be expected to last. You may be experiencing a fluke period where everything is working beyond its apparent limitations but I wouldn’t take that as evidence that it will continue to do so indefinitely. I would enjoy it while it lasts but don’t be disappointed when it eventually stops either.

    Allow me to clear up the confusion, Alan:


    Throughout this discussion, we've assumed JSB and Kempermaniac had both their S/PDIF inputs and outputs connected to their interfaces, probably because they didn't indicate otherwise in all those posts:

    I am using Internal source for clock sync, tested both 6i6 and 18i8 now; with, 96KHz, 128 samples, works fine.

    I can play my Kemper head through S/PDIF with internal clocking of the interface too.

    I remember being told that Head and Rack would never be S/PDIF Slave, but I really only wanted not to have to change the Sync Clock source on my AI - which I'm no longer doing. I no longer have to set my AI at External or S/PDIF. But will it last?

    Except I didn't have any clicks, at 96Khz, 128 samples. If you haven't tried it, give it a shot.

    I updated to 7.1.2 release, and am still able to run Internal clock sync for S/PDIF, cleanly. I would've thought people would be happy about this.

    Finally, in post #558, he clarifies by confirming that it's set up as described by digbob earlier.

    This is what I'm experiencing, and am able to use Internal sync with S/PDIF.

    JSB and Kempermaniac appear to only be using the S/PDIF inputs on their KPAs. If they'd connected their outputs at the same time and attempted to listen without setting their IF clocks to external (Kemper in this case), it'd be a different story.

  • Thanks MM! I wasn't trying to belabor the point, that I have some special KPA or interface, just that the Internal interface clock sync seems to be working with 7.1.2 (release works for me too).


    I do only have the output S/PDIF cable connected to my KPA .


    And yes, this wouldn't be the first time that the Internal sync worked, and was then broken later in updates. I'm enjoying it for the moment.

  • On my side in and out are both connected all the time. But atm I only use Kemper Out to Interface In (for monitoring via my studio speakers).

    You mean analogue out from the Kemper, Stephan?


    If it's the S/PDIF out from the KPA to the AI, the AI will have to be set as the slave (external clock) and the Kemper to master (internal clock). In this case, you'll be able to listen to both the KPA's S/PDIF in and out without issues.


    When the AI's clock is set to internal, there's no way IMHO that your S/PDIF out from the Kemper won't be clicking and popping, except on rare, "lucky" occasions, which is why I asked if you meant one of the analogue outs.

  • Turns out I do have both the In and Out S/PDIF cables connected to my AI (18i8) here. I'm not using the DAW out/KPA in channel, just have the cables plugged in to both channels.


    At the friends house (6i6), I was connected to KPA Out only.


    I'm not using the re-amp feature at all, but yes, with both S/PDIF cables connected, Internal sync works fine for me, at the moment.

  • Running latest OS for Windows. Updated last time, a few days ago. Was hoping it would fix the issue I had come up from the update prior. My favorites folder view isn't working. Either the Kemper thinks every rig is a favorite or none of them are. Seem to think it either made every preset a favorite, as if none were, going to that setting would show nothing. Anyone have a fix? If not, how do I go backwards with OS updates?

    I just updated on Saturday and this is happening to me too...I cycled through to "My Rigs" (which I don't have anything in) and then when I went back to favorites it was working normal again. Also, several new rigs that I "favorited" weren't showing up but doing that helped that too. (I'm on Mac though FWIW)


    On Sunday, everything seemed to be ok so maybe a power cycle helped?

  • I had the same problem with Favorites yesterday.
    After the Kemper booted up, it was not on the rig previously chosen when i powered it off but on a random rig from my pool. The selector was on "favorites", but instead all rigs were displayed. I had to switch back and forth between different modes "own rigs/all/by author" then back on favorites for it to work.

    It's not about whether or not they're both connected, mate. I'm talking about not being able to monitor, without clicks and pops, the KPA's S/PDIF out whilst it's slaved (via S/PDIF) to your interface. That slaving will sync the KPA's S/PDIF input only. The only way to have both S/PDIF in and out synced properly is to set the KPA as master and your AI as slave.


    As I said to Kempermaniac:

    If it's the S/PDIF out from the KPA to the AI, the AI will have to be set as the slave (external clock) and the Kemper to master (internal clock). In this case, you'll be able to listen to both the KPA's S/PDIF in and out without issues.

    I've got it, believe me.


    Focusrite 18i8 set to Internal clock sync, KPA plugged to S/PDIF IN and OUT - no clicks, no pops - happy, thanks. Not reamping.

    If you're able to use the S/PDIF out from the Kemper whilst it's synced to your AI using the S/PDIF input without issues, as Damian and I have mentioned earlier, luck must be on your side.


    I'm very interested to hear how long this works for you, JSB. If you don't mind, please keep us updated, mate. :/

  • I thought this was bizarre too, seriously. This also worked once before, with 7.0.5.

    To make things even stranger, I'm running 96KHz both here, and at the friends house - same result. I hope this becomes a feature, and not a serendipitous bug.

  • You mean analogue out from the Kemper, Stephan?

    Sorry for the late response. No, I mean S/PDIF. To be honest I'm not monitoring very often via S/PDIF. I remember some occasional clicks but it didn't bother me much. Most of the time I'm monitoring via Monitor Out to CLR.

    I’m sure many would also hope so (me included)


    However, as CK has said on a number of occasions that it will never be possible due to hardware limitations, I think it might be safer to err on the side of serendipity 😉

  • @Mods


    Is it possible to have an update on the acoustic simulator?Is it "ready" and will come soon or is it still far away?Some information would be nice.

    I am really trying to be patient about this one but I can't hide that some info would be nice since I "really need something like this"..


    So again..please dear Kemper-team..some update would be nice.I was on the verge to get me another acoustic SIM since the end of 2018 but I did not proceed when it was announced early this yyear.I don't need an exact release date.Just something like "it is planned to be released this year.." etc would be nice.
