Footswitch as On/Off Switch
Starting again with the
basic “Patching a Module” patch we are going to add a footswitch
controlled modulation source. The footswitch will be used to turn the modulation on and
off.
Both switches are patched in exactly the same way. The jacks are arranged in a simple
double pole layout. The center jack is the wiper and the connection flips between the left
and right jacks. That means when the LED is off, the center jack is connected to the left
jack and when the LED is on, the center jack is connected to the right jack.
This patch connects the triangle wave output of an LFO to the right jack of Switch 1. The
center jack is patched to the Frequency CV input of the Filter module. That means that
when the footswitch LED is lit, the LFO will modulate the Filter and when the footswitch
LED is off, the modulation will also be off.
This patch does not utilize the expression pedal inputs.
