Cubase 13 - Mono -> Stereo on External Instruments


I have some mono hardware synth configured as External Instruments in Cubase.
To put some stereo FX in this track i have to route to a stereo group.
Now inCubase 13 there is a new feature to make audio channel to stereo, so how to do it for my external instruments?

One approach: configure the external mono instrument as a stereo instrument and connect your synth to the left input (leave the right input unconnected). Then use the MonoToStereo plugin. For “true” mono, use the mono option in the plugin. The result is a stereo track with both channels being equal. From there on, stereo effects should work as you want them to.


Thanks, that’s a great solution.

Pro: I don’t need to use Bus channel anymore

Cons: Using MonoToStereo plugin for “true” mono, it will reduce -6db of volume

I believe an issue that still remains with this approach is that you lose half of your hardware inputs. Is there a way yet to have a mono input source, using one hardware input, and apply stereo effects to that without routing to a bus?

I didn’t understand when you say about losing hardare input.

I’m connecting only one input source of my synth on a stereo channel with this solution.

The solution above really makes sense and you don’t need to use bus anymore.

Yes, if you route a Mono Input to a Stereo Audio Track it will record a centered Mono signal on the Stereo Track. You shouldn’t need to do anything fancy - just choose a Mono Source for the Stereo Track. Been like this for ages. A lot of folks here always record Audio in Stereo for both Mono & Stereo signals.

However since you are using Cubase 13 can’t you just use the new Stereo/Mono switch on the Tracks/Channels.
