The ASSIMIL8OR works with high-quality 24-bit AD and DA converters. Internally, however, sample and bit rate for lo-fi sound can be lowered, the latter is even CV-controllable. The samples can also be otherwise manipulated in many ways. Thus, the phase of a sample via CV or a different sample can be modulated. Likewise, the loop points can be controlled and the sample can be traversed with CV control (scrubbing), whereby wavetable similar effects could be achieved. The following parameters can be addressed via the gate / trigger and CV inputs:
- Bit Depth
- Phase Modulation
- Sample Start
- Sample Length
- Loop Start
- Loop Length
- Release Decay
Samples and presets are stored on an SD card, which is easily accessible plugged into the module front.
For EVOLUTION, Dave has designed new capabilities that not only allow you to dial in all of the outstanding qualities of the original 2100, but combine to let you create the sonic characteristics of a wide variety of other filter types.
- 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 you vary the signal level into the ladder, letting you 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 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), rivalling 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.
And like all Rossum Electro-Music modules, it's solidly built, with machined aluminium knobs and high quality components throughout.
The MORPHEUS Eurorack module includes over 280 filter configurations, what we call Cubes. Each Cube is composed of up to 8 complex filters that you can picture as being at the corners of a three dimensional cube (hence the name). Morpheus gives you 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 in one dimension, but 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 the MORPHEUS filter module, you now have simultaneous real-time CV control of all three dimensions, for dynamic timbral effects unlike anything you've ever heard before. In stereo.
With one or more Satellites, you can take advantage of all of your Control Forge 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.
In addition to direct connection with a Control Forge or other Satellite, presets and preset sequences can also be loaded via audio file archives that have been saved from a Control Forge or Satellite. And since those files can be posted online and downloaded, it’s a great way to share and exchange presets.
