The Tetra is another Dave Smith designed piece of analog wizardry that sits somewhere between their Prophet '08 poly-synth and its monophonic desktop module counterpart, the Mopho. In fact, other than the new Prophet '08 themed paint scheme and knobs, the Tetra's case and layout is virtually identical to the Mopho. What the Tetra offers is four-voice polyphony and multitimbral capability using the same acclaimed analog technology of the Prophet '08. It is essentially four Mopho's in one, or a mini Prophet sound module.

Tetra

Der Evolver ist ein monophoner Hybrid-Synthesizer, der die analoge und digitale Welt in einem kompakten Desktop-Gehäuse vereint. Er verfügt über zwei analoge DCOs und zwei digitale Wavetable-Oszillatoren, die auf dem legendären Sequential Prophet VS basieren. Das Gerät nutzt echte analoge Curtis-Tiefpassfilter und bietet einen vollständig stereofonen Signalweg mit unabhängigen Filtern pro Kanal. Ein integrierter 16x4-Step-Sequenzer ermöglicht komplexe, modulierende Klänge und rhythmische Texturen. Dave Smith entwickelte dieses bahnbrechende Design kurz nach seiner Zusammenarbeit mit Roger Linn am Adrenalinn-Pedal.

The unit utilizes genuine analog Curtis low-pass filters and offers a true stereo signal path with independent filters per channel. An integrated 16x4 step sequencer allows for complex, evolving sounds and rhythmic textures. Dave Smith developed this pioneering design shortly after his collaboration with Roger Linn on the Adrenalinn pedal.

Evolver Desktop

Mopho is a compact and affordable—but powerful—monophonic analog synthesizer. The voice architecture is similar to a single voice of the Prophet ’08, but with a couple of twists to distinguish it from its award-winning sibling. We’ve added two sub-octave generators—one per oscillator—for additional girth and crushing basses. It also has an audio input that lets you process external audio and mix Mopho’s own audio output back in pre-filter for feedback effects that can range from subtle distortion to extreme skronk. The Push It button is a manual trigger that lets you play a specific note or latch notes and sequences on. It can also step through a sequence to play short melodic lines without a keyboard. Of course, Mopho can also be used with a MIDI controller or external sequencer.
