How do I properly setup multi band pass filters in Audiokit?

Question

I would like to setup many band pass filters in AudioKit, to separate a sound source into many bands, each for further processing down the bus/chain.

AudioKit has nodes in a sequence or bus. Each node has input, does something, and output. For the graphic EQ [1], the example passes each band's node to the next band's node of the EQ. But, for a band-pass filter, I would assume that each band pass filter node would have the same input. Otherwise, only the passband would pass to the next band pass filter which would then find nothing for itself to pass...

Say I have band pass filter 1 at 1000 Hz with bandwidth of 1000, band pass filter 2 at 2000 Hz with bandwidth of 1000, etc. If filter 2's input was filter 1's output, filter 2's output would be nothing.

I believe this is what I want:

              / band pass filter 1 --> more processing...
sound source -> band pass filter 2 --> more processing...
              \ band pass filter 3 --> more processing...

vs

sound source -> band pass filter 1 -> band pass filter 2 ...

Right?

Definitely the first one, you are correct.
