You should be able to set most of that up with simply creating ChannelGroups and using addGroup. The second output from Group Wav to Group A will require manually adding a connection between the head DSP of Group Wav and the tail DSP of Group A.

Have you seen the dsp\_effect\_per\_speaker example we ship? It demonstrates how to do these kind of connections.
