Sequential Switch Matrix Expander - 8HP

WMD Sequential Switch Matrix Expander

The WMD Sequential Switch Matrix Expander does exactly what is advertised: expands the capabilities of the Sequential Switch Matrix module. The module enables a Gate/Trig function, with the Gate function providing dedicated 10V outs for each routing button, and the Trigger function sending synchronized triggers whenever a step happens. 

Additionally, the module features adjustable trigger length (via CV or a dedicated knob), retrig-on-step functionality, and invert behavior. 

Sequential Switch Matrix Expander Features

  • Gate/Trig: Gate (Green LED lit) provides 10V outputs for each routing button. It mirrors the routing shown by the SSM LEDs. Trig mode (Red LED lit) will output a trigger when a step (CV, Step/Gate or Reset) is taken. Pushing a routing button will not change the output thus providing synchronized triggers.
  • Trigger Length: CV and knob provide adjustable trigger length.
  • Retrig on Step: When on, gates and triggers will retrigger quickly when a step is taken.
  • Invert Behavior: When on, routings that are OFF will produce ON triggers or Gates.
  • DAC3/4: Two 4 bit DAC outputs that output a weighted 4 bit voltage between 0 and 5 volts. From routing columns 3 and 4.
  • Step: Outputs a trigger for each step, reset or CV change that is made to the SSM.
  • Installation: Connect the 20 pin ribbon cable to the GTExp header on the SSM, and the ToSSM connector on the Expand. Red Stripe Down.
