Hi,

Could this method of adding several triggers to an output via diodes be put
on the DIY page?

Thank you
Sylvain

  For adding/combining gate or trigger signals a precision CV adder can be
  used but would go over the top. In the precision adder a lot of manually
  selected resistors (selected to 0.1% precision) and active electronics
with
  operational amplifiers is used and will contribute to the price of the
  module. A module for the combination of gate/trigger signals could be
  realized much easier without active electronics: nothing but e.g. seven
  sockets connected to an eighth socket via diodes. Such a module could be
  manufactered much cheaper (same price range as a multiple).

  Maybe we will have to add more simple modules for all these jobs (like
  switched multiple, gate/trigger combiner, manual gate, precision CV
adder).

  Best wishes
