Introduction
The Behringer LM DRUM is a versatile drum machine that recreates the iconic sounds of the first sample-based drum machines from the 1980s. It enhances these with a more adaptable programming environment, inspired by the RD-8 and RD-9, and offers the ability to sample sounds and create custom banks. The LM DRUM features up-to-date MIDI and USB connectivity, individual voice outputs, and can be integrated with electronic drumkits or pads for instrument-like playability with full velocity sensitivity. This manual aims to guide you in customizing your LM DRUM to your specific needs and maximizing its potential.

The second screen accessed via the data control allows editing of sample parameters like Level, Start, Length, Loop, Playback mode, Tuning, and Level.
Step Size, Probability, Flam, Polymeter, Filter
Step Size
Sets the duration of each step in a pattern (e.g., 1/8th note, 1/16th triplet). The available options depend on the global or pattern setting.
Probability
Allows for random activation of drums on specific steps within a pattern. A probability of 100% means the drum always sounds, 50% means it sounds half the time, and 0% means it never sounds. This can be set per drum, per step, or globally.
Flam
Introduces a slight timing variation (flam) to drum sounds. The amount and application (per drum, per step) are configurable.
Polymeter
Enables different step lengths for different drums within a single pattern, creating complex rhythmic relationships rather than polyrhythms.
Filter
A dual-mode filter (Low Pass/High Pass) with adjustable cutoff frequency and resonance. Filter automation can be recorded into patterns.
MIDI Map & Trigger Assign
MIDI Map
Allows re-assignment of MIDI notes to individual drum sounds. The defaults map standard MIDI notes to specific drums for both transmit (TX) and receive (RX) functions.
Trigger Assign
Configures the three analog trigger outputs on the rear panel to trigger specific drums. These settings are global.
Bitcrusher, Metronome, Options, About
Bitcrusher
Reduces the bit depth of sounds (from 11-bit down to 1-bit) to introduce graininess and distortion, altering the sound's character.
Metronome
The metronome can be switched off or set to sound on a specified number of beats (1-9). It can be used for real-time programming.
Options
This sub-menu offers various miscellaneous settings, including Random Closed Hat, Velocity THD, Velocity Sensitive Pad, Chromatic MIDI In, Sample Record Mode (AGC, Normalized, Raw), Auto Save, Beep On/Off, LCD Brightness, and LED Brightness.
About
Displays current firmware versions for the MCUs and allows restoration of factory settings. A backup of custom programming is recommended before performing a factory reset.
Wave Designer, Analog Filter, Volume, Input
Wave Designer
Allows alteration of the transients of selected drums via Attack and Sustain controls. This affects the main outputs and feeds into the analog filter.
Analog Filter
A dual-mode filter (Low Pass/High Pass) that modifies the timbre of sounds. It can be switched on or off, and its cutoff frequency and resonance are adjustable. Filter automation can be recorded.

Programming
The LM DRUM offers flexible programming options through a hierarchical selection process: Song -> Pattern -> Parameter settings.
Step Time Programming
Patterns can be created step-by-step with the playhead running or stopped. Drums are selected via Voice Select buttons (53), and steps are triggered by pressing the Step buttons. Double presses can select alternate sample variations for certain drums.
Real Time Programming
Patterns can be programmed in real time using the Step/Pad buttons, an external MIDI keyboard, or electronic drum pads. Sounds are recorded with velocity sensitivity, which can be edited later. Quantization is recommended for precise timing.
Chromatic Programming and Playing
Allows for playing and recording tunable sounds chromatically using the pads or an external MIDI keyboard. Octave can be adjusted. MIDI channels for chromatic voices can be configured via SynthTribe.
Micro Timing
Enables fine adjustment of step timing, shifting steps slightly ahead or behind the beat.
Creating a Song
Songs are constructed by chaining patterns. Users can select patterns for each slot, set repeat counts, and choose an end mode (Stop, Loop, Hold). The LM DRUM supports up to eight songs at a time.
Chaining Patterns
Patterns can be played sequentially by selecting the next pattern while the current one is playing.
Chaining Songs
Songs can be chained similarly to patterns, allowing for seamless transitions between songs.
Setlist
A Setlist feature allows songs to be arranged in a specific order and repeated. Each slot can be configured for a specific number of plays.
Sampling
The LM DRUM allows users to create and use their own samples. This can be done directly via the Rec Input socket or by loading .wav files into the SynthTribe software and downloading them.
Direct Sampling
Connect an audio source to the rear panel's Rec Input (57). Select a bank, then use the Sample button (20) to activate recording. Adjust Input Level (48) and Threshold. Press Yes to arm, and Tap + Yes to start recording. After recording, samples can be trimmed, previewed, discarded, or saved. The sample can then be named and assigned to a pad.
Using SynthTribe
.wav files (under 1MB) can be loaded into SynthTribe, converted to mono 12-bit/24kHz format, and downloaded to the LM DRUM. SynthTribe also includes a Librarian function for backing up and restoring samples.
Sample Management
Access the sample menu by pressing and holding Tap and then pressing Sample. This displays all samples in memory. Default samples in banks 1-7 are locked and cannot be deleted. Options include Select All, Deselect All, Load to Bank, Delete, Trim, and Rename.
