to make my case more clear I modify my question:
My observation is:
1) An input signal coming from an analog input in a DSP7000 is converted and then split up in two separate signals within the machine. One is driving the FX engine, the other one gets fed to the output directly in order to allow the DRY/WET setting to control the amount of dry signal.
2) The input nodes in VSIG represent the path of signal driving the FX unit, which means I can redirect only the wet portion of the signal to an output.
Conclusion: The path of the dry signal is hardwired, such that if I feed a signal to Input 1 this is directly fed to the Output 1 and there is no way to have the dry IN1 signal path redirected to OUT2.
