The LDB-2e Analog Drums Eurorack Module

The LDB-2e “Little Drummer Boy” analog drums Eurorack module is an update to our popular LDB-1e module. It is 6 HP (only 2HP wider) and now includes the individual volume controls and output jacks functionality of the old expansion module.
The LDB-2x expansion module is totally new and gives you knob and CV control of the pitch of every drum, and the decay of the kick and open hi-hat.

Trigger Man - Trigger/Gate Sequencer Eurorack Module V2

The Deptronics Trigger Man Eurorack module unique trigger/gate sequencer with a revolutionary interface that enables you to create any sequence with just two knobs.

It has 8 pattern memories (sets of 8X8 sequences), which can be played back in any order and chained into a series of patterns up to 100 patterns long. There are even two CV input jacks to control the sequences, patterns, or tempo. All of this fits in a very compact 8 HP wide module.

New Version 2 firmware update adds tons of powerful new features in the same hardware!

Thunderclap Analog Hand Clap Stompbox / Module

The Delptronics Thunderclap is a classic analog hand clap effect based on the famous hand clap sound of the TR-808 and TR-909 drum machines with extra knobs to tweak the sound from claps to finger snaps to snares to cymbals to thunderous crashes.

The Thunderclap is available as an Eurorack module, or a stompbox in a heavy-duty aluminum enclosure with awesome graphics. It is also available as a Eurorack module or stompbox kit.


ThunderBell Analog Cowbell

The Deptronics ThunderBell is a classic analog voltage controlled cowbell. The circuit is inspired by the great cowbell sound in the Korg KR-55. The ThunderBell adds voltage controlled pitch and the Eurorack module version also includes voltage controlled decay.

The ThunderBell is available as an assembled Eurorack module, assembled inside an actuall cowbell, or as a kit.


LDB-1 Analog Drum Machine

The LDB-1 “Little Drummer Boy” is a modern recreation of the classic analog drum machines of the 80's, like the Roland TR-606 and TR-808. Our goal was to recreate the warm sounds of the classics, using all analog circuitry - not samples. The brain of the LDB-1 is a powerful digital microcontroller that triggers the analog drum sounds and provides the sequencer, programmability and connectivity features. Easily interfaces with other instruments, synthesizers, DAWs, etc. through analog connections, MIDI, and DINsync.


Bender Sequencer

A step sequencer for controlling circuit-bent devices that were never even designed to be controlled. Available as a kit or fully assembled.
