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 white noise which is the source of the ‘snappy’ part of the sound is available at the NOISE output directly and
unprocessed.
The trigger LED will light each time a trigger pulse is received.

Introduction
The SD88 is an accurate replica of the TR808 snare drum sound. The
module is entirely discrete analogue circuitry, based as closely as possible
on the original. The snare sound is made up of two oscillators mixed with
filtered noise.
The SD88 can produce more than just snare drum
sounds...
The SD88 has additional controls to change noise decay (De cay)
and High Pass Filter cut-off (HPF) on the filtered noise. This enables
a wide range of snares, noise hits, and bongo/conga type sounds
