We've posted a video of Dave Rossum demonstrating his new modules at the show, but here's the full details of each as seen in the company's press releases:

Rossum Electro-Music EVOLUTION Variable Character Ladder Filter
At the core of Evolution is Dave Rossum's enhancement of the iconic Moog ladder filter from the original E-mu Systems 2100 LPF module (which, incidentally, Dave counts as his favorite sounding of all of the analog filters he has designed).

For Evolution, Dave has designed new capabilities that not only allow users to dial in all of the outstanding qualities of the original 2100, but combine to let them create the sonic characteristics of a wide variety of other filter types.

They include:

  • A Genus control that allows continuous voltage control of the number of filter poles (from 3 to 6 poles), essentially allowing real-time variation of Evolution's effective cutoff slope from 18dB/oct to 36dB/oct. LEDs give continuous indication of the current slope.
  • A Species control that lets users vary the signal level into the ladder, letting them control the intensity of the filter's characteristic distortion. When in self-oscillation mode, this control modulates the amplitude of Evolution's output.
  • Voltage controlled resonance with a variable Q Level Compensation control that controls of the balance of the resonant peak and the frequencies below the cutoff frequency (which would otherwise be attenuated as the resonance is increased).
  • An extremely accurate and temperature-stable frequency control exponential generator (accurate over 10 octaves), rivaling the specifications of the best analog VCOs.


Taken together, EVOLUTION gives you everything from the platonic ideal of the classic ladder filter to a vast selection of alternative filter characteristics.

Like all Rossum Electro-Music modules, Evolution is solidly built, with machined aluminum knobs and high quality components throughout.


Rossum Electro-Music CONTROL FORGE Programmable Universal CV Generator
Control Forge's core functionality is drawn from the E-mu Morpheus's insanely powerful (but hard to program on a two-line display) Function Generators. But now expanded into a supremely flexible modulation source encompassing elaborate one-shot contours, evolving cyclical patterns and sequences of arbitrary length and complexity.

  • At its most basic, ControlForge an 8-stage function generator with variable time and target voltage level for each stage.
  • Each stage's level can be defined either absolutely or relative to the ending level of the previous stage and can optionally be quantized to the nearest 1/12 volt.
  • Each stage's level may have a user defined range of randomness of either linear or gaussian distribution.
  • The time scale may be modulated under CV control or manually via the encoder during runtime.
  • There are 67 different transition shapes between stages (indicated graphically on the display during selection), from linear and exponential shapes to various flavors of random, chaotic, and many more that don't lend themselves to one-word descriptions, including the ability to pass CVs directly through to the output for individual stages.
  • Also included are "DC" shapes that allow the module to be used as a sequencer with all of the module's available programmability. When combined with the Preset Sequencer described below, sequences can be hundreds of steps long and modified in real time manually or by CVs.
  • Each stage may optionally have a conditional jump mode that results in a jump to another selected stage if a particular condition is met. E.g., a CV being above or below the selected conditional value, the presence or lack of a gate or logic high at their respective inputs, rising or falling edges at the inputs, etc. So, in addition to one-shot shapes, extremely elaborate cyclical patterns can be programmed that evolve based on the various conditional inputs.
  • Two independent triggers can be programmed to fire in response to a variety of events and can be used to affect either Control Forge itself or external modules.
  • Hundreds of presets can be saved and recalled
  • A preset sequencer allows stepping through user defined series of presets under trigger or clock control. This allows contours and sequences of almost unlimited length and complexity.
  • All presets and sequences can be transferred to any number of Control Forge Satellites, which can then operate as stand-alone modulation sources, completely independent of the Control Forge.


Like all Rossum Electro-Music digital modules, all parameters are available for adjustment with a single button press. No menu diving.



Rossum Electro-Music MORPHEUS Stereo Morphing Z-Plane Filter
Based on the groundbreaking 14-pole Z­-Plane Filters that Dave Rossum invented for the E-mu System's Morpheus synthesizer, Rossum Electro-Music's Morpheus Eurorack module includes over 190 filter configurations. Each configuration is composed of up to 8 complex filters that one can picture as being at the corners of a three dimensional cube. Morpheus then gives users the ability to smoothly interpolate between those 8 filters within the cube's three dimensional space.

Due to processor limitations back in the day, the original Morpheus was capable of real-time morphing between filter configurations in only one dimension. Interpolation in the frequency and transform dimensions were set at note-on and remained static for the remainder of the note. But even with that limitation, Morpheus offered sonic capabilities that are unmatched to this day.

With Rossum Electro-Music's new Morpheus module, musicians and sound designers now get simultaneous real-time manual and CV control of all three dimensions, for dynamic timbral effects unlike anything ever heard before.

Morpheus features include:

  • Over 190 14-pole filter configurations
  • Real-time manual and CV control of Frequency, Morphing and Transformation
  • The ability to save hundreds of customized filter configurations
  • A sequencer for stepping through filter configurations under trigger or clock control
  • A large OLED display for programming and realtime display of morphing


Like all Rossum Electro-Music digital modules, all parameters are available for adjustment with a single button press. No menu diving.

Rossum Electro-Music SATELLITE Universal CV Generator
Satellite is a compact 12HP module that can be loaded with all of the presets and preset sequences from a Control Forge and then function as a completely stand-alone CV generator. Once the presets and preset sequences are transferred from the Control Forge (via a patch cord connection), Satellite no longer requires any connection to a Control Forge.

With one or more Satellites, Control Forge owners can take advantage of all of their presets and sequences in multiple cabinets or even different systems

Multiple Satellites can be programmed from the same Control Forge and synced together via their Gate inputs to create complex polyphonic sequences and modulation contours.

Pricing and Availability:
Available shortly from Rossum Electro-Music dealers worldwide.
