Not all inputs showing in Side-Chain list

richardjay · January 18, 2019, 10:01pm

The list of available inputs in the new ‘Add Side-Chain Input’ (C10.0.10 on Win7 x64) is not showing all of the inputs that are in my project.

In Cubase 9.x the only way to send a sidechain to a suitable VST was to use the sends. In C10, this is what I see as the avaiable list of sends

This is correct and shows the same in C9.x

But in the ‘Add Side-Chain Input’ window this is what I see:

See how the REV FX channels are missing (SHORT REV, MED REV, etc.) … so is SLAPBACK and the 1/4 DL. And the BUSS_REST group channel. And it gets even more messy as I add new tracks or channels, with things starting to appear and disappear from this list Side-Chain input window.

Same issue here…

Also using Cubase 10 Pro. And the list of available sources for side chains is incomplete.

I want to trigger a compressor with a stereo recording right now but only the left channel track is available as a side chain input. The right channel and the stereo group channel are missing. I can neither select them from the new add sidechain dialogue in the plug-in (standard compressor) nor can I send the right track or the group channel to the respective compressor.

And I remember that I had a similar situation just the other day in a different project.

This is a serious issue…Please provide a quick fix Steinberg.

Thanks for confirming. I opened a support ticket at mySteinberg but have had no reply … could you do the same ?

Any news about this issue?

Having the same issue. Screwing up my project badly as half of my vocal tracks are not showing up in the sidechain list.

I’ve had this problem occur oftentimes with all versions of C10.

Is this bug being ignored?

Having exactly the same issue in Cubase Pro 12 & 13.

Missing sidechain source channels. Anybody has a solution?

Possible cause and SOLUTION

I had exactly the same problem in C12 just 15 minutes ago:

Compressor plugin on group channel
wanted to “set up side chain routing” (little gear wheel at the top)
drop down “Add Side-Chain Source” didn’t show group channels

While deleting unused tracks from the project I stumbled across redundant FX Channels. My project contains 7 FX Channels. These had obviously been accidentally doublicated.

SOLUTION:

After deleting the redudant 7 FX Channels, the Add SC Source dropdown menu showed all channels again!

SOLUTION: Tracks that have an output on each of their eight sends are not visible in the sidechain list. Delete at least one send and the track will be visible in the sidechain list.
