ALM Eurorack cases are available in a range of sizes all including an integrated powered bus boards.

The cases all feature anodised aluminium construction, an on/off switch, rubber feet, and high quality switched powered bus boards with numerous keyed headers and ample power capacity.

These are simple and compact Eurorack cases, perfect for small, focused systems, taking along on travels, or as a tabletop addition to a larger setup.

Cases are available in 4 sizes; 3U 84HP / 6U 84HP / 9U 84HP / 3U 52HP / 6U 52HP sizes. They all offer at least 1 Amp on both the -12V and +12V rails per row.

Great modern cases

The ALM powered Eurorack case was originally designed for the System Coupe. Wider interest has seen it evolve into a range of different sized cases being made available by themselves.

A fixed solid bus board provides quality ample power and plentiful keyed power connectors. The shielded DC/DC power converter is low noise and includes overload and short circuit protection. Fixed, quality mounting rails are used over sometimes frustrating sliding nuts. The case has a great looking all anodised aluminium construction that is both strong and light.

The case proportions are designed to look great on a table or desk (not too deep, just enough) and also be easy to fit in a bag and transport.

Decksaver case covers are available currently for the 3U/84HP, 6U/52HP, and 6U/84HP cases.

Notes: Another banger from ALM. Based on the oscillators from the classic 1980s Casio CZ series, the Cizzle uses phase distortion synthesis for characterful, FM-adjacent synth tones.

Supplier's Notes:
The 'CIZZLE' is a dual digital 'phase distortion' VCO inspired by the classic Casio 'CZ' series synthesizers. It brings the specifics of 'CZ' style phase distortion (PD) synthesis into Eurorack with the inclusion of primary and secondary oscillator layering and detuning (with up to 8 voice chord generation), extended morphable PD wave generation algorithms, unique resonance wave generation, plus specific 'end of chain' ring modulation and noise modes that are key to the CZ sound.

The voices also feature built in VCAs and various modulation controls and inputs, a cv-able chord mode, tracking ability, triggered mode switching and can be output independently or mixed with stereo widening.

The 'CIZZLE' finally brings characteristic CZ style synthesis to Eurorack with a rich palette of sounds from mellow ambient tones, 90s Detroit Techno inspired chords, Reese style basses, and synth tones with unique faux resonance squelch.

Ideal For

Flexible and precise primary digital voice duties in a Eurorack system.
Creating basslines, rich chords, drones, morphing tones, percussive hits etc.
Unique digital squelch.

Notes: The 'Mega Milton' is a smorgasbord of handy all analogue utilities in just 8HP that will greatly extend the functionality of your Eurorack system.

It includes a stereo line input converter for incorporating line level external sources into a Eurorack system, a fixed 4 input mixer with breakout attenuator for combining signals, a gated slew limiter for adding slides to sequences, a sample and hold with analogue white noise with a myriad of uses such as generative melodies or producing percussive textures and finally a buffered mult for droop free signal distribution with handy LEDs to monitor.

All sections are normalised to help with typical use cases such as generating random CV from the sample & hold section, a smooth random source from the slew output and breaking out a standalone attenuator from the fourth mixer input.

The 'Mega Milton' provides essential classic synthesizer building blocks for patching in any Eurorack system.

Ideal For

Incorporating stereo external sources easily into your Eurorack system.
Signal attenuation and basic mixing in a small space.
Building percussion sounds from an analogue noise source.
Producing clocked random to add interest and variation to patterns and sounds.
Adding gated 303 style slides to patterns.
Creating and Manipulating patterns with Sample and Hold.
Buffering and monitoring voltage across multiple VCOs or other destinations with no drop.

Notes: Think of the MFD like a tiny DJ mixer: two stereo inputs, one stereo output, with the option to cue either input and crossfade between the two. A simple idea very well executed.

Supplier's Notes:
Inspired by DJ mixers, the MFD allows you to cue and crossfade between signals. Ideal for live performance as well as jamming out ideas in the studio.

Supplier's Notes:
The 'MFD' is a 2-channel stereo crossfader designed for live DJ-style mixing and jamming in Eurorack. Two mono or stereo inputs are mixed to a single stereo output via direct or voltage control. Additional Cue controls provide preview monitoring of either input pre-mix via dedicated Cue switches and an output.

Voltage control over the crossfade and DC coupling allow for further creative uses such as a high quality stereo VCA or as a mix processor for either stereo audio signals or CV.

The MFD is designed to have very low noise and cross bleed and employs equal power crossfading for smooth constant level blending between signal sources.

Features:

Two channel stereo crossfader with voltage control.
Approx equal power crossfading.
Cue output switches for direct monitoring of either stereo input (pairing well with HPO for headphone monitoring).
Can be used as a high quality stereo VCA.
DC coupled for use with both audio and CV.
Skiff friendly with reverse power protection.
Two year warranty.
Made in England.

Ideal For:

Smoothly blending and monitoring 'tracks' or 'scenes' during a live set.
High quality VCA use for stereo based sources.
Voltage controlled crossfading and mixing of both CV and Audio signals.
Other advanced uses including audio rate modulation, stereo panning effects and a CV controlled FX send.
