Question:
Why are my Object ID Index numbers off by two or more?
Example; RTE for output is index 32 instead of 30?

Answer:
If you change an input from Mono to Stereo, it will increase the number of input objects and that will change the index number scheme causing the index numbers to increase. Each input that you change will change the index numbers. Switching from Stereo to Mono will reduce the Index numbers.
