Reply to Xone:42 4 Channel EQ Trick

Ok, guys insomnia gave me a sudden inspiration! I own my Xone:42 for about 2 months now and a trick came to my mind, call me dump if you already know or if it's totally logical ...

I plugged a cinch cable from FX send directly into FX return and activated the EFX VFC button.
Know you can use the filter for each channel by regulating it with the EFX D/W knob

Crazy came just to my mind and what to share the idea with all of you guys
