MFB's Berlin-based approach to synthesis has always favored compact, feature-dense designs, and the Synth Pro represents their most ambitious polyphonic statement yet—eight voices of analog circuitry packed into a desktop unit that refuses to compromise on sound or control.
The Synth Pro runs eight voltage-controlled oscillators across its voice architecture, with three oscillators per voice offering sawtooth, triangle, square, and ring modulation waveforms. The synthesis engine centers on dual multimode filters that can operate in stereo-spread configuration, giving you lowpass, bandpass, and highpass modes with resonance control that pushes into self-oscillation. Two envelope generators and two LFOs provide modulation sources, while the filter section accepts modulation from multiple simultaneous destinations including velocity and the mod wheel. The unit includes a built-in effects processor with reverb, echo, chorus, and additional effect types, all routed through a stereo output stage with dedicated headphone output. Control-wise you get pitch and modulation wheels, a polyphonic step sequencer with up to 16 steps, an arpeggiator, and 240 preset and sequencer memory locations. MIDI in via 5-pin DIN lets you sequence from external gear, while CV/Gate inputs provide modular integration.
The Synth Pro has earned respect in the community for delivering genuine polyphonic analog character in a surprisingly manageable footprint, with particular praise for its bass capabilities and the flexibility of its multi-timbral modes that let you run it as eight independent mono synths or various split configurations. The stereo filter architecture and comprehensive modulation options give it surprising depth for sound design, though some users note the compact layout means menu diving for deeper parameter access.
