Rossum Electro-Music Mob Of Emus, A Polyfunctional Module With Endless Options

Mob of Emus is Dave Rossum’s take on the classic multi-function Eurorack module expanded with a polyfunctional harmonic concept that enables endless function combinations.

Dave Rossum is still one of the legendary developers in the Synthesizer world today. With development such as the EMU systems or the iconic SP1200 sampler, he became known worldwide. The pension is also in 2020, not insight. Dave is still busy developing new, innovative products. Currently only in Euroack format. And these are very interesting but also complex.

The new module of Rossum Electro-Music is called Mob of Emus and is a 16HP multi-functional Eurorack module.

Rossum Electro-Music Mob Of Emus

Six channels are available and each gives you oscillators, noise sources, cyclical and 1-shot modulators (LFOs, envelopes, and various other shapes). Then sample & hold waveshapes, slow random modulators, triggers, rhythm patterns, and quantization (of both internal and external signals) in ‘pretty much any combination.

You can set all 6 channels separately, but there is an option that makes it easier. In the hex mode, the module provides you a macro control layer that allows you to control all of its channels simultaneously. But the function maintains the relationships of each channel’s independent programming. Very handy indeed. Mob of Emus is not just another multi-functional module with tons of features à la disting mk4. No, Dave Rossum goes one step further. He brings a new twist to the multi-function concept

The module’s “harmonic” control structure also makes it easy to combine its oscillators into rich additive timbres, to combine its LFOs into stacked harmonic low-frequency modulation waves, and to create modulation sources and triggers with polyrhythmic patterns. It has an external trigger input, six CV inputs (operation in six different control modes), six independent outputs, and an assignable output. Thanks to its large number of functions and possibilities for combining, you can discover something new in the module every day.


  • Six channels that can function independently or can be further controlled by a Hex Mode macro layer that lets you control all six simultaneously. Channels can be:
    • Wide-range digital oscillators
    • Noise sources
    • Cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes)
    • Sample and hold waveshapes
    • Slow random modulators
    • Triggers
    • Rhythm patterns
    • Quantizers (of both internal and external(!) signals)
  • Six CV inputs that can function in six different control modes
  • Eight real-time controls for immediate access to key channel parameters
  • Six individual channel outputs and an assignable mix output
  • The ability to store and recall 12 user presets
  • And much more…

Rossum Electro-Music Mob of Emus will be available in late November 2020. Price TBA.
