Massive Sound with a Micro Footprint

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.

Moho is fully programmable and all parameters can be tweaked from the front panel. The four Assignable Parameters controls are assignable per program for optimum performance control. A free editor is available for Mac OS and Windows to facilitate programming. (And if you already have a Prophet ’08, most Mopho parameters can be controlled from the Prophet’s font panel via MIDI.)

Mopho is perfect for people who want to learn the ins and outs of real analog synthesis without spending a bundle, DJs looking to add some old school sonic spice to their setups, and musicians who appreciate a great-sounding, very portable mono synth.
