In the workshop we build a functional clone of the circuit, using contemporary replacements for op-amps and transistors. in the module are controls for Accent, Decay, Tone and Level, like in the original. it has a trigger input and a sound output with a jack connector and possibility to use external accent input. All the known modification points are marked in the paperboard. | In the workshop we build a functional clone of the circuit, using contemporary replacements for op-amps and transistors. in the module are controls for Accent, Decay, Tone and Level, like in the original. it has a trigger input and a sound output with a jack connector and possibility to use external accent input.

The original circuit expects two different triggers, the actual trigger and the accent trigger, to arrive exactly at the same time and to be 1 ms long.To allow triggering with a button, we have to add in a small conditioning circuit. This makes it possible to also trigger the bass drum with another sound that has a strong and fast transient, for example hi-hat sound. it also can be triggered with any cmos style triggers, for example with an arduino. | The original circuit expects two different triggers, the actual trigger and the accent trigger, to arrive exactly at the same time and to be 1 ms long.To allow triggering with a button, we have to add in a small conditioning circuit.
