GTT does not support feedback connection in signal flow. For example it is not possible to connect Gain_2_0_0 to Matrix_Mixer_1_0_0 in below Signal Flow, as this connection leads to loop.
Hence if user tries to connect any audio objects which will leads to loop, a notification is shown that “Connection is not possible”.
For legacy project :
If signal flow already has a feedback loop, in that case designer will highlight Audio Objects in loop and compiler error will be reported as shown below.
To save signal flow user has to remove existing loops.
There is no restriction to add loops in control signals.
