Klar tut das auch in SX2 gehen (Stichwort: Quadro-[g=183]BUs[/g])
Der Einfachheit halt halber paste ich das mal aus anderen Beiträgen hier rein:
1. Erstellen einer Gruppenspur mit Konfiguration Quadro
2. in dieser Gruppe deinen Sidechain-Comp. laden
3. Ausgang deines [g=118]Bass[/g] oder Synthie oder was auch immer auf die Gruppe routen
4. SorroundPan mit y-Mirrow auf die hinteren beiden Ecken dràngen
5. deine Drums (Bassdrum...) im send auf die Group routen und auf PreFader stellen
6. Diesen Kanal routen (von normal auf routing)
7. SorroundPan mit y-Mirrow auf die vorderen beiden Ecken dràngen
8. Abspielen
9. Comp. einstellen.
Detailed description of "True Stereo Side-Chaining" with
Voxengo Crunchessor in [g=539]Cubase[/g] SX2:
(testet with Crunchessor1.6 und [g=539]Cubase[/g] SX2.2.039):
==========================================================
The following example will use a kick drum track to duck/compress a [g=118]bass[/g] line track:
1) Create a Quadro group (L,R,LS,RS).
2) Route the [g=118]bass[/g] track to the Quadro group.
a) Open the SurroundPan window in the [g=118]bass[/g] track by double-click on the pan-view in the mixer.
b) Here you must set the Mode Mo./St to Y-Mirror (By default it is set to Mono-Mix).
c) Set the grey panning balls in the SurroundPan window to 100% left and right
and pan it to L/R. This means the L-ball sits at top-left, the R-ball sits
at top-right in the SurroundPan view.
3) Route a send-slot of the kick track to the Quadro group.
(Of course you can route the kick track directly to the Quadro group,
but you won't hear the kick drum at the stereo output [g=183]bus[/g] in this case)
a) Set Pre-Fader switch to ON (the "at" symbol).
(It is necessary to retain the control over the volume slider for the kick track)
b) Set the Send-Amount slider to 0 (CTRL left click on the slider).
c) Change the view of the send-slot to "Routing" (little window above the send slots).
d) Open the SurroundPan window by double-click the (now visible) pan-view in the send slot.
e) Do the same as in 2b)
f) Set the grey panning balls in the SurroundPan window to 100% left and right
and pan it to LS/RS. This means the L-ball sits at bottom-left, the R-ball sits
at bottom-right in the SurroundPan view.
4) [g=84]Insert[/g] crunchessor in an [g=84]insert[/g]-slot of the Quadro group
Start with the preset "Club is pumping" (or pull the Drive-knob to maximum)
in Crunchessor to see/hear the effect.
Choose a Side-Chain [g=190]channel[/g] in crunchessor (in this case "SC: 3+4").
Leave the Crunchessor window open to see the effect via the [g=105]gain[/g] reduction meter:
When the kick drum sets in, the [g=118]bass[/g] track will be ducked/compressed according to the
[g=322]compressor[/g] settings applied to the plug-in.
You can do this the same way with 2 mono tracks, although I think you could leave
the Mode Mo./St in the SurroundPan views to "Mono-Mix". Experiment a [g=395]bit[/g] !
Addition: There's also another "quick" way to do side-chaining with Quadro Output-[g=183]Bus[/g] instead of Quadro-Group:
1) Define a new Quadro Output-[g=183]Bus[/g] and there 2 child/sub-busses ("Stereo" and "Stereo (Rs Ls)").
2) Route [g=118]Bass[/g] track to "Stereo" and Kick track to "Stereo (Rs Ls)".
3) [g=84]Insert[/g] Crunchessor in the Quadro [g=183]bus[/g].
You don't have to fiddle with Pan-Settings with this method but has its disadvantage in SX2
that you don't have further routing possibilities with the Quadro [g=183]bus[/g].
