The Trip/Fire is a very handy dual utility Euro Rack module in
4HP. The top half is a full featured comparator, and the
bottom module is a multi-mode trigger/gate delay. It is great
for creating new rhythms, triggering envelopes, and all
kinds of modular experiments!
The comparator uses a reference level to compare against
the input. If the input is higher than the reference then the
output goes high. The reference source is an external input
passed through an attenuverter. If no source is plugged into
the REF input an internal source is used.
The output of the comparator is normaled to the input of the
Gate/Trigger delay, meaning that any gates derived from the
comparator pass down to the trigger/gate delay unless
another source is plugged into the trigger/gate delay input.
The delay section is an event/edge recorder with one trigger
delay mode and 2 gate delay modes. Trigger delay senses
trigger inputs and delays them before sending to the output.
The first gate mode outputs a delayed gate open input but
outputs a gate close without delay. The other gate mode
delays both the gate open and gate closed input. The delay
range is about 1 second and jumper settable to about 8
This 4HP module has a maximum 40mA current draw.
