Dave Smith Instruments Mopho

The DSI Mopho is a deceitfully small monophonic analog synthesizer capable of producing deep sounds. Its internal voice is similar to that of the Prophet ’08 with some added features. 

The unit contains an all-analog signal path and a single voice consisting of two oscillators, each with their own sub-octave generator. There’s also an audio input, allowing users to process external audio through the Mopho’s onboard Curtis low-pass filter and accompanying envelopes.

Users can also feed the Mopho’s audio back into the Mopho through its audio input for some interesting feedback effects. Additionally, the unit features a Push It button that acts as a manual trigger able to influence several parameters, including triggering/modifying notes and sequences, and stepping through sequences on-the-fly.

No keyboard? No problem! The Mopho can be controlled via MIDI input using any compatible MIDI controller, and is extremely easy to program via an intuitive front panel. There is also a free editor available for use with an external computer that should help to streamline sound programming.
