Moog MF-105M MIDI MuRF
MuRF stands for "Multiple Resonance Filter Array". The MIDI MuRF is a filter sequencer, capable of creating animated filter effects across eight frequency bands. These warm and resonant filters can be applied to any sound source: guitars, synthesizers, vocals, etc. All processing is 100% analog and its parameters can be controlled from MIDI, expression pedals or CV-compatible instruments.
Third in a series of MuRF pedals, the MF-105M MIDI MuRF combines all of the features of its two predecessors and takes the idea of the filter sequencer even further. There were three limitations of the original MF-105, all of which have finally been addressed by the MF-105M.
Firstly, the original MF-105 was better suited to guitar and mid-range frequencies. The MF-105B follow-up was aimed at those who wanted a more bass-friendly unit. But with the MF-105M, the user can now switch between Mids or Bass frequency bands to animate the desired frequencies:
BASS - 110 Hz, 160 Hz, 240 Hz, 350 Hz, 525 Hz, 775 Hz, 1.2kHz,
MIDS - 200 Hz, 300 Hz, 450 Hz, 675 Hz, 1kHz, 1.5 kHz, 2.2 kHz, 3.4kHz.
Secondly, the older MF-105s were difficult to sync in a MIDI studio. The new MIDI In of the MF-105M allows perfect MIDI-clock synchronization with DAWs, drum machines, and other devices. Continuous Control (CC) MIDI data allows the user to start, re-start, and stop the pattern as well.
Thirdly, the patterns on the older units were fun but not editable. With the MF-105M, the user can create original patterns. Moog shipped a free Mac/PC sequence editor that allows the user to easily draw custom patterns and transfer them to the MIDI MuRF. All of the front panel controls can also be controlled from the software editor as well.
Like all Moogerfoogers, the MF-105M is designed to be anything from a foot pedal effect unit to part of a modular synthesis system. With its tap/step and rate jacks, even those who stay clear of MIDI (or synthesizers) will find the MIDI MuRF is a great tool for animating their sounds in creative new ways. In fact, a Moog expression pedal or MP-201 is great for getting more expressiveness out of the unit. Whether it's morphing drones, stuttering lead lines, filtering drum patterns, or space age sequences, the Moog MIDI MuRF delivers the goods.
