Can someone explain why Logic does this?

So if I run a synth in EXS24 through a few plugins (amp designers, eq, comp etc) it will sound different to when I send (an no output) the same synth to an audio track with the exact same channel strip.

It's really annoying because I run a lot of synths and instruments to the channel audio channel strips that come with Logic. I can seem to find anyway to browse these and put them onto a software instrument track.

To be more precise, are you talking about sending (routing) the signal to an "aux channel"?

The plugins within the channel itself receives the signal pre-fader. If you route the signal further downstream to an aux channel, the plugins receive the signal post-fader. Are you sending the signal at unity gain to the aux channel? Maybe that's your difference?

I have no experience with a real board etc so I've never really treated Logic like that. So I just refer to tracks as audio, midi or a bus when I send multiple things it (I guess I treat a bus like a folder).



I've attached pic. (the plugins on the right hand soft synth track are different I know but let's say they're the same)

My send is post fader.

Ok, let's pretend the inserts are exactly the same so we'll ignore that difference.

In your screenshot, your fader of "Amp Cabi 2" is currently at -3.7dB -- which means the inserts on aux channel "Crunch Blu 1" actually "hears" the quieter input signal at -3.7dB. On the other hand, the inserts on "Perry Synt 3" will "hear" the signal at 0.0dB because inserts within that strip see the signal before the fader (pre fader).

Try adjusting "Amp Cabi 2" fader to be 0.0dB unity gain and see if the sound is the same. (Btw, you might think you can switch the send mode to "pre fader" but that setting still applies channel EQ so the resulting sound won't be identical.)
