Using SFP as External FX in Nuendo?

This is a follow-up question to the one I posted earlier (many thanks for the answers to that, BTW!)

I have been experimenting with using SFP as an External FX in Nuendo. I do this by attaching the External FX to a free Input and Output, and then connecting the corresponding Asio2 source and Asio2 dest in my Routing Window through the desired effect (say, a compressor).

That way, I can use this effect as a plug-in in an FX channel and send any channel I want to the compressor.

The problem is that I'm not hearing what I should be hearing. When I attach the effect inside the Routing Window, the track instantly gets louder, even though I haven't turned on the send. Also, getting the dry/wet slider to work as it usually does on a send effect is proving diffiult.

Can you look at my setup and see if I'm doing anything horrifically wrong?

i wonder if the ASIO output 1 LR is sending the master mix LR from Nuendo to your STM input 9 LR which is then adding to your volume - i remember in Cubase VST i used to leave output 1LR unconnected because they were hard wired to the master output and wasn't much use. i apprecaite that Nuemdo is more advanced and so may not have this problem.

Personally i never work the way you do in your screenshots. i would take audio out as you do, add compressor as you do but then feed that signal into the STM to be mixed - they way you're doing it you're half mixing in Nuendo and half in Scope - i prefer to do the whole thing in Scope and bypass the Nuendo summing completely. Also in this instance it's a vocal so i would just use the Left leg of the signal, you're not gaining anything in using stereo. Also i can't see how a dry/wet fader would work at all in this set-up - you just have to send the max level to the effect - again another reason to work in Scope only.

THank you once again for the great and fast response. I will try it out once my headache subsides from listening to the same vocal loop for 2 hours

How would the dry/wet fader thing work within scope? Surely you'd still just be turning the volume on the output of the compressor up and down. Even if you have a seperate dry channel for the vocals and do a dry/wet-thing by turning up the volume of the compressed track, you'd still get unwanted gain on the final sound (unless you simultaneously turned down the dry track).

Or is this a blatant case of RTFM?

It looks like the send bus is set up wrong in Nuendo - shouldn't they be on Scope 15 & 16 to correspond to the asio 8L & 8R?

Well we're not really talking wet/dry here as such - compression isn't generally mixed back in with the original signal (although this is a technique, just not that common). If you mix everything through Scope this is what you will achieve:

1) You will send everything from Nuendo to Scope.

2) All ASIO Sources will appear in Scope, be mixed and compressed etc in Scope.

3) The stereo output of Scope can then be send to your monitors to hear the results.

This way you will not hear any mixing through Nuendo, so you will not hear the uneffected (dry) vocal.
