Sorry for the perhaps obvious question… but I can’t seem to find an answer in the documentation, and through testing.

How many input and output channels are available for the MCC with the Moku Pro in multi instrument mode? The documentation [here](https://compile.liquidinstruments.com/docs/io.html#inputs-and-outputs) seems to suggest that two inputs and two outputs are available for the moku pro.

However, when I add the MCC instrument to the block diagram, there are two inputs, and four outputs. I tested the function using a simple passthrough program, passing InputA and B to the Outputs A, B, C and D, and it seems that they are all functional.

Are the Inputs C and D also available? If I add them to the VHDL program, they dont appear in the block diagram.

Thanks,  
Claude
