Module	Description	Controls & Ins/Outs
	BD88 Bass/Tom/Conga Drum Module 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!	Inputs: Trigger socket 5-12V Accent socket 0-12V Outputs: 3.5mm audio out 6.35mm audio out Power: +/-12V Controls: Tune, Tone, Decay, Level Indicators: Trigger LED Size: 10HP

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

Level Sets output level
