Created an external instrument with my hardware synth

In Cubase I have sound even with Local Off enabled. This is normal since the piano is connected with MIDI (via USB) and audio (via audio interface).

I haven’t any problem if I don’t connect the piano as an external instrument : I can play/record midi/audio normally.

It’s when I use the Nord as an external instrument that I have this double signal when playing, even with midi local off.

Could it have something to do with using “Direct Monitoring”? (Studio → Studio Setup → Audio System)

Sorry but I don’t find any option “direct monitoring” in Studio → Studio Setup → Audio System.

Hi,

Are you on Mac? This is Windows only.


I’m on Windows but I don’t see it.

Ok, it’s here but I can’t enable it.
I suppose my Scarlett 8i6 doesn’t support it.

Ok, this seems to rule out any settings in Cubase.
Can you maybe ask on the Focusrite support forum if somebody knows what is going on? It could be a setting of your audio interface.

Hi all,
I think you are monitoring the piano twice when using the external instrument. You are first monitoring the audio from the piano directly through the focusrite input to the focusrite output (via the focusrite mixer, probably to be able to listen the piano when playing without cubase), and also monitoring the same piano thtough cubase’s outputs via the external instrument (with a few milliseconds of latency, causing the phasing effect).

The only way I found to solve the problem is to mute the piano audio inputs on my audio interface (Scarlett 8i6).

But in this case I have to reactivate it every time when I want to play the piano outside of Cubase…

Sorry, I’ve just seen you are aware of this double monitoring.
In this case, due to your setup (the need to listen to your piano when you play outside of cubase), you should mute the piano input in the focusrite mixer when working with cubase, or instead recording without monitoring the external instrument through cubase’s ouputs.

Exactly @JoanH
This connection allows me to play the piano without computer using the audio interface in standalone mode.

If I want to use the Nord as an external instrument in Cubase, the only solution I found is to mute the piano inputs in the Focusrite control.

By doing this I no longer have the phasing effect and everything works. I just have to remember to unmute the entries when done. Not so restrictive I suppose although I would have liked to find a way to not have to mute the entries.

I totally agree with you.

Thanks a lot for your help, this confirms what I thought.
