Confusion about DSP Type

FMOD Engine
1

Hi,everybody:
I want to add some DSP types in my code,but I do not know how it plays.
eg.When I add EQ and LOWPASS DSPtype,then how it plays? First Process EQ data, and base on EQ effect to process lowpass type ,or not?
Anyone can help me?

When you add a DSP to a channel, you also need to specify an index offset to add this DSP unit at in the DSP chain. This determines the order that the DSP’s are processed in.
