Behringer LM DRUM

Classic Hybrid Sampling Drum Machine

Introduction

The Behringer LM DRUM is not just a recreation of the first sample based drum machine from the 1980s. On top of its iconic sounds the LM DRUM adds a more versatile programming environment, adapted from the RD-8 and RD-9; and the option to sample sounds and create banks of your own to use as you wish. It comes with up to date MIDI and USB connectivity, outputs for every voice, and can be linked to an electronic drumkit or pads and played as an instrument, with full velocity sensitivity. This manual is designed to help you customize your LM DRUM to your own requirements, and to help you get the best out of it. It is arranged in the same way as the Quick Start Guide that came in the box, but is able to go into much more depth.
