The RC88 is an accurate replica of the TR808 rimshot and claves sounds. The module is entirely discrete analogue circuitry, based as closely as possible on the original.

Inputs:
Trigger socket 5-12V
Accent socket 0-12V

Outputs:
3.5mm audio out
6.35mm audio out

Power:
+/-12V

Controls:
Tune, RS HPF, RS/CL select switch, 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 sound up or down

RS HPF Changes the tone of the rimshot sound by adjusting the cut-off of an internal high pass filter.

Switch This selects either the rimshot (RS) or the claves (CL) sound.

Level Sets output level
