Send SysEx to VoiceLive 3 when Preset is changed on VL3

Hello.

I use StreamByter (SB) in MidiDesigner Pro2 (MD2) to read and update VoiceLive 3 Extreme (VL3x).

I send a SysEx message to VL3x to request an update of items. "Guitar Gain". (SND F0 .... F7).
VL3x then sends a SysEx message to MD2 which updates "Guitar Gain" in MD2.
This works well.

But I now have trouble updating MD2 when changing presets on VL3x:

In the MD2 log, I see that I get this message:"Message In: Length = 2: C1 52" + several other settings.
If I press the next preset on VL3x, I read in the log "Message In: Length = 2: C1 53" + several other settings etc.

I mean I have to use "Input Rules" in SB and then I wrote this code:

IF M0 == C1 #Received a new preset from VL3x
   SND F0 .... F7 #Send a request for new parameter for ex. "Guitar Gain"
END

But with this code in "Input Rules" I see in the log that I receive the same SysEx value I sent out.
So no SysEx update from VL3x i requested for.

So...
What am I doing wrong nic
