The long anticipated Morpheus from Rossum Electro Music is about to arrive. London Modular have started taking pre-orders which is a good indication of its imminent arrival. Designed by Dave Rossum, co-founder of E-mu Systems, the Morpheus digital filter module brings the power of the 14-pole Z-plane filters from the E-mu Morpheus synthesizer to Eurorack.



It’s a stereo morphing Z-plane filter with over 280 filter configurations. The filters are visualised as a 3D cube, where each corner represents one of 8 complex filters. The module then enables you to interpolate smoothly between the filters within three-dimensional space.

The original Morpheus was only capable of real-time morphing in a single dimension. With the Morpheus module you can move in all three dimensions simultaneously, in real-time, in stereo.

It’s probably simpler to see and hear in action that to try to explain what’s going on. There’s very few videos available at the moment as only a couple of special people have got their hands on one. One such person is DivKid who posted this sumptuous example of a simple patch where you can see the screen showing the morphing filter position.

More Information

Other features include over 190 14-pole filter configurations, with 289 filter cubes, 1000 filters, 200 filter sequences and 20,000 dynamically allocated sequence steps. There’s manual and CV control of frequency, morphing and transformation. The sequencer steps through filter configurations via trigger or clock control. There’s this gorgeous OLED display, and every parameter has a knob or button on the front panel.

I love the idea of taking something awesome out of an old digital synthesizer and making it available in Eurorack format. I always enjoyed playing the E-mu Morpheus when I worked at the Turnkey Music Store back in the 1990’s. Dave has brought it up-to-date, ramped up the DSP power and it can now be enjoyed in completely fresh configurations. What a stunning piece of work.

The Morpheus Morphing Z-Plane Filter is available any time now and can be pre-ordered for £459 including VAT. More information on the Rossum Electro Music website.
