E-Mu Systems Morpheus Z-Plane Synthesizer

   (0 reviews)

Morpheus is a completely new type of music synthesizer which represents a major landmark in the evolution of electronic sound synthesis. Many electronic instruments involve the technology of sampling, where sounds are digitally recorded and played back at different pitches. Sampling has the advantage of highly accurate and realistic sound. One disadvantage of sampling is that once the sounds are recorded, it is difficult to change them in any significant way.

Morpheus introduces the Z-Plane filter, which has the ability to smoothly change its function over time. This ultra-powerful device can accurately simulate the resonance of musical instruments, the human voice or create entirely new timbres. The Z-Plane filter is composed of up to eight complex filters for unprecedented control over subtle aspects of the sound.

Morpheus contains eight megabytes (internally expandable to 16 megabytes) of the highest quality 16 bit samples as the basis for its sounds. These sounds can be combined or spliced, modulated and then shaped through one of 197 Z-Plane filters. Sampled sounds can now be re-shaped and expressively controlled.

The 16 bit sound samples are arranged into 256 preset locations, 128 of which are user-programmable. 128 user-programmable Hyperpresets allow ultra-flexible keyboard mapping of presets. The optional memory
card lets you create an expandable library of your favorite presets and hyperpresets.

Morpheus features two studio-quality effects processors with 28 different effects to choose from. Hyperpresets allow you to have up to 32 different sounds on the keyboard at one time in any desired arrangement. Sounds can be placed side by side or layered with velocity control. The ability to respond multi-timbrally to all 16 MIDI channels makes Morpheus ideally suited for multitrack sequencing and composing using a MIDI sequencer.

Other features include 3 stereo outputs for individually processing sounds (also configurable as 6 polyphonic submixes with fully programmable panning), integral sends and returns to allow the addition of external effects units without the need for a separate mixer, user definable alternate tuning, and of course, an extensive MIDI implementation.
