Recording Via Spdif Issue

Netheravon · Aug 9th 2014

Hi All,

I'm using Pro Logic X and a Komplete Audio 6 interface. I have the Kemper Spdif output set to Git/Stack. I have the interface in sync with the Kemper acting as the external clock at 44.1.

Here's my problem, hopefully someone can help.

I'm trying to record guitar on two mono tracks: one wet and one dry for later possible reamping. The spdif for the interface is 5/6 so I set one track input for 5, one for 6. I am only getting a dry signal from the kemper no matter what I do on input 5. I also tried just setting one track as 5/6 just to see if I got the same issue and I do, then it just records one channel (the left I think) and nothing on the right: i.e. dry but not wet.
If I change the spdif output to something that is only wet, e.g. Stack then I get no signal at all.

Am I doing something wrong? I've just spent 4 hours searching the net/manual and messing with Pro Logic and can't get it to work.

I have reamped before with no prob, but then I just used the plugins in Pro Logic to get the guitar sound while recording and then reamped the dry signal later on.

Thanks for any help. I know I'm probably missing something obvious but after 4 hours at this non-stop I am going a little mad!

What is SPDIF in the profiler's output menu set to?

Heya
The spdif in the output menu (by holding down the output button) is set to git/stack. If I set it to Stack I get no signal at all. Anything where there's one dry and one wet I just get the dry.

Hey

First of all, thank you for taking the time to summarize your settings WRT output etc. Much appreciated

Check the output section, the last page under the "master" button - check that the SPDIF volume is not set to - infinity or something like that.

Next (and this is where I'm betting your problem is - maybe do this first instead :-)): click the input button, and verify that the "Input source" is set to "front input" - not "spdif input reamp" or somesuch. The latter setting actually passes the dry signal through from the front input.

OK think I've worked it out. The spdif output vol was on 0. No idea why as it's linked to master Vol and that certainly wasn't. All very confusing, but hopefully sorted now

Just typed the above as Michael must have typing too! Thanks for the advice mate, it was set to -inf!

Glad you got it sorted

Had to be something alone these lines! Great you got it sorted!

Thx a lot for the help and input! Love this forum;)

Hmmm... I wonder how the link thing works - I have not used it much myself - but if you engage the link while e.g. the master vol is at full and the spdif vol is as -40... Does it retain the numeric difference between those two, so that if you turned down the master volume a good bit, would that all but turn off the SPDIF?

I only did this with the volume of main and monitor out. When they are linked they keep the numerical difference.

Just did a little experimenting with this. The volume scales are logarhithmic, so if your master is at 1.6, and you link your e.g. monitor volume when it is at -35, then turning the master volume 0.2 lops off like 30 dB of the linked volume from -35 to -60 - i.e., due to the lower resolution at those lower levels. Kind of makes sense - but also kind of doesn't, from a usability viewpoint

The master volume, of course, is not dB, but a zero to ten scale.

Yes, it's much more practical to unlink them IMO.
As for the SPDIF volume I'd unlink it as well but would set (and forget) it in the output menu.

Netheravon · Aug 11th 2014

Yeah, good point Ingolf, I think I'll do that.
