The LDB-1se Analog Drum Machine Kit

The LDB-1se is the second edition of Delptronics' modern classic LDB-1 “Little Drummer Boy” Analog Drum Machine. Our goal was to recreate the warm analog sounds of the legendary 80's machines, like the Roland TR-606 and TR-808. The brain of the LDB-1se is a microcontroller that is more powerful that anything available in the 80's, enabling us to provide all the features of a modern drum machine sequencer.

Easily interfaces with other instruments, synthesizers, drum machines, sequencers, DAWs, etc. through analog connections, MIDI, and DINsync.

Many more parts and features than the original LDB-1 kit — at the same price.

Video demo coming soon.
