The code below returns the following when it would be expected to show 1: 1.000 , 2: 2.00 etc. With outargs set it works ok, and also the inverse (outargs but no inargs) works OK. Is there a problem with my code or is it possibly a bug?

struct testopcode : csnd::Plugin<0, 4> {
    static constexpr char const *otypes = "";
    static constexpr char const *itypes = "iiii";
    
    int init() {
        for (int i = 0; i < 4 ; i++) {
            std::string info = std::to_string(i+1) + ": " + std::to_string(inargs[i]);
            csound->message(info);
        }
        return OK;
    }
};

...
testopcode 1, 2, 3, 4
...

1: 2.000000
2: 3.000000
3: 4.000000

Ah ok, thanks! I will go with your second suggestion and basically switch round in/out.

yep, using 0 for outargs is problematic. A solution, which might sound confusing, but should work is to set outargs to 1 and use outargs[0] as your first input. You'll

also reduce the number of inargs by 1 as well. 

Or, set zero input args and use the outargs array as your inputs.

I might make a separate class template for zero outputs to make it less confusing, but

for now, one of the above should work.

I’ve added the class InPlug for the case where there are no outputs. It’s in GIT, not sure if you can try it.

Great, thank you. I have tried it, and it works :)
