The Drumbox is a drum machine soundbox with 6 sounds. The originial idea for this module came from this website (in french). My first version was not fully operational.
I modified it to make it work with Eurorack, then I saw that Sam from LMNC did a similar version, so I did use his work to upgrade my version, which is now basicaly a clone of his :).
Basic DrumMachine, 6 sounds:
- Kick
- High and Low Bongo
- Clave
- Snare (using the Noise and LowBongo at the same time)
- Noise
Decay control on all those sounds. No CV.
Individual outputs per sound and one mix output.

Build Informations
Regular build, I use ceramic capacitors and box capacitors.
When building modules, always do it in this order (from smallest component to highest):
- diodes
- resistors
- DIP chips
- capacitors (film/ceramic/box)
- Transistors
- Electrolytic capacitors
To solder the headers, place them and place both PCBs in their final position before fully soldering the pin headers/sockets.
For the next parts, always place them without soldering them on:
- jacks, pots and switches that go throught the front panel
Once placed, put the front panel in place, then fasten all components to it. Once this is done, you can solder all the remaining components.
