In the two-day workshop participants build a Paper-Synthesizer 808KD, a Kick Drum Module, a Functional Clone of Tr-808 Bass Drum. It is The sound of 80´s hip hop and electro and one of the most cloned and copied electronic musical circuits of all time. Clever functionality of this particular circuit provides a good starting point for learning analog percussive sound synthesis.
This board is a functional clone of the circuit, using contemporary replacements for op-amps and transistors. The module has 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.
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. You can find a more detailed explanation on the modifications here. Read more >
