4 modulation sources -> 4 inputs of seq switch
output of sequential switch -> modulation input of some module
some trigger source -> switch input

1 modulation source -> input of sequential switch
outputs of seq switch -> 4 different modulation inputs
some trigger source -> switch input

2 sequencers -> 2 inputs of seq switch
output of seq switch -> vco pitch input
some trigger source (possibly last or first step from one of the sequencers) -> switch input

remember to switch no of steps in the seq switch 2,3,4

remember that switch is bi-directional - inputs become outputs and vice versa depending on how it's patched

examples refer to the doepfer a-151 - but may also apply equally to other sequential switches

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities
