Use
The trigger input has a range of about 5 to 12V. A trigger pulse of around 1mS is recommended, although the gate
output of a synth can be used. 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.
Controls
Tune Tunes the bass drum up or down
Tone Controls ‘click’ level (like stick hitting drum skin). The click you hear is actually the trigger pulse.
Decay Sets decay time

Introduction
The BD88 is an accurate replica of the TR808 bass drum sound. The
module is entirely discrete analogue circuitry, based as closely as possible
on the original.
The BD88 can produce more than just bass drum sounds...
The BD88 has the addition of a tune control. This enables the
pitch to be brought right up. This in conjunction with short decay times
allows TR808 style Toms and Congas to be produced.
☺
The BD88 can be tuned way low with long decays... watch your
bass bins mate!
