Use
The trigger input has a range of about 5 to 12V. A trigger or gate signal of at least 5V will trigger the sound. A larger
trigger pulse will increase the level of the sound (accent the notes). When the accent socket is used, the trigger input
socket only triggers the sound and the level of the sound is controlled by the voltage of the CV at the accent socket.
The accent voltage can be from another trigger pulse generator, or from an LFO or Envelope. When using for example
an LFO, you can have the level changing with the LFO sweep.
The trigger LED will light each time a trigger pulse is received.

Introduction
The CB88 is an accurate replica of the TR808 cowbell sound. The module is
entirely discrete analogue circuitry, based as closely as possible on the original.
The sound is made up from 2 square wave oscillators whose pitch can manually
be adjusted. To create the cowbell sound though, they are tune close together
so they beat.
The CB88 can produce more than just cowbell sounds...
By tuning the 2 oscillators to equal pitch a synth sound is produced,
which can be tuned to the melodies in your music.
