This problem is even harder in adversarial systems like blockchain. Google’s engineers synchronize these clocks to a very high percision and constantly maintain them. Google’s Spanner uses synchronized atomic clocks between its datacenters. What I'm not sure about though is the "externally clocked" checkbox - I'm presuming I need to check this, as well as setting spdif in my audio interface, when using Kemper as master clock - I'll have to try it I suppose once my spdif cables arrive.One of the most difficult problems in distributed systems is agreement on time. if my interface is set at 48 and open a project at 44.1, it'll change it automatically. I think Cubase also controls the sample rate based on project settings - e.g. If the interface is the master, this can happen more elegantly without you needing to manually change the kemper, then re-clock the interface etc the Kemper should just follow.

Some software also tries to control the audio interface settings (Pro Tools, for example), so loading up a session can change sample rate to match the previous settings. If you have a means of reliably measuring your input latency, I guess you can apply this numerically rather than visually.Īs for which clock should be master, unless your interface lifts its output relays when re-clocking, I'd keep it on internal and avoid it blatting through your speakers/headphones.

When recording I monitor via an analogue desk, so direct from Kemper and mixed with the DAW playback, then shuffle the audio regions earlier in Pro Tools as required. no S/PDIF) involved I measured latency at just over 2.5 ms to main outs, which is a good result considering the A/D D/A stages. Is it possible this was the other way around, as in, the latency was high when operating at 44.1kHz? I thought it was addressed in one of the beta releases but looking back through the change log I can only spot the 'reduced latency at 44.1kHz' note from v7.5. Regarding the extra latency at sample rates other than 44.1 kHz, can you remember what the values creep up to? I remember there was a discussion on it but can't locate the thread now.
This? I used to assume my computer controlled the word clock - but having read up on it, it seems the computer itself has nothing to do with the word clock?ĮDIT: - I've just noticed in the Kemper's output settings, above clock speed, you can toggle the button for "internal" or "auto" - so is "auto" for using the Kemper as slave to my audio interface's internal word clock? In which case I don't have to worry about switching back and forth any word clock settings when connecting/disconnecting the Kemper? Or is there any benefit to having the Kemper as master? Is controlled by my audio interface, right? And Cubase is slave to
Sure I’m understanding the word clock correctly – by default this Kemper, and what happens if I forget? Or will my system automatically revert to using the QuantumĢ626’s internal clock as master when I disconnect or power down the Is this all I need to do, or do I need toĬhange any settings in my DAW (Cubase 11) as well?Ĭhange word clock settings each time I connect or disconnect the Options for word clock in my Quantum 2626 control software – it’sĬurrently set to “internal”, so presumably I’d change it to "spdif" if Kemper connected. To be the master clock? If so, where do I need to set this? I can see
Thing… I usually work at 48khz, and I see I can set the Kemper to Quantum 2626) I just need a single cable, from Kemper OUT toĪudio-interface IN, and that this needs to be an RCA coaxialĬonnector? I would only need a second cable (from audio interface OUT Understanding that to connect Kemper to audio interface (Presonus
Up on both, but bear with me if I’ve made any incorrect These are admittedly blind spots in my knowledge. Used spdif, and never had cause to change word clock settings - so Not new to music computer tech, or audio engineering, I’ve never I’ve read through them all by now… but just wanted to doubleĬheck a few specific/practical things that I’m still not 100% clear And elsewhere, about connecting Kemper via spdif – I think
