Jesper, you need at least 6 of these pins, 1 of them is ground and (most of)
the other ones the single channel inputs. I think, I sent you the SDS8
schematics already. The sequencer input circuitry wants to have a fat level
like the SDS6 is able to output. But you can easily sequence the SDS8 by
using the normal pad inputs and drive them with something like a clave or
sidestick sample.
