You cant do it like that, cause as i described above, the inlets are for chaining, not for turning on/off the steps. I though that first too, but they are not for that.
Its possible to make a sequencer that loads presets that lets you change the steps/toggles and save them using mouse.
But I am not sure how to use external controls, for example a midi controller to turn on/off the different steps/toggles. Cause all 16 steps in a sequencer is basically regarded as ONE parameter.
Anyway, to access parameters and change them, the only way is coding it. You can check ctrl/hook on how to acces the parameters and write to them. The functions is called
"PExParameterChange". And this works 100%, but as technobear says, this is not super easy to do.
