Each filter's gain is also controlled by the "Animator," a pattern generator that supplies envelopes to the eight filters, adjusting their levels in 12 different rhythmic patterns. Adjustments to the filters' sliders can add further rhythmic and timbral variation. The MuRF also has a tap tempo input for syncing the Animator to the beat of the music.
A wide selection of sequencing patterns is available, and the sequencing rate may be varied from extremely slow to extremely fast. The range of effects runs from gentle, slow-moving sound clouds, to deeply rhythmic grooves, to totally wild tone transmutations. Sequence selection, sequencing rate, envelope shape, and direct mix may be played in real time.
MuRF shares the musician-oriented features that are common to all Moogerfoogers. All the audio processing is 100% genuine analog, for warm, fat sound quality. Any line level or instrument level audio signal may be processed. Wide-ranging player parameters may be controlled from the panel knobs as well as from expression pedals or analog synthesis instruments. Components are rugged and long lasting, to withstand the rigors of stage and studio. Finally, the MuRF is housed in the classic Moogerfooger "double-wedge" enclosure that may be used on a table or on the floor.
The MuRF is an entirely new class of effects that is expected to ship by the end of the first quarter 2004.
