I'm trying to write a dummy 4-in 4-out MSP external, and ran into some weird observations.
Basically I'm trying to open 4 signal inlets and outlets, add some gains to each incoming signal, and pass through inlet 1 signal to outlet 1, inlet 2 to outlet 2, and so on. After loaded, only outlet 1 gets audio and others are silent. I also tried letting inlet 1 talk to all 4 outlets, and it works. Just when having multiple input signals, things start acting funky.
Could you help take a look what's wrong in this external? I have attached the file. Thanks a bunch!
