JoMoX SunSyn

DesktopHybridPolyphonic

When Jomox released the SunSyn in 2000, they set out to prove that a modern synthesizer could be genuinely, unapologetically analog while still embracing digital possibilities. The result was a machine that feels like it belongs in the same conversation as the legendary modular systems of the 1970s, except it fits on a desktop and remembers your patches.

The SunSyn gives you eight voices of polyphonic synthesis, each one a complete synthesizer unto itself. Every voice has two true analog VCOs built from discrete circuits, delivering the classic sawtooth, square, and pulse waveforms with pulsewidth modulation. But here's where it gets interesting: alongside those analog oscillators sit two Ramp Controlled Oscillators, which are essentially wavetable engines that track and respond to modulation with the same precision and feel as analog circuits. This hybrid approach lets you blend analog warmth with digital complexity in ways that sound organic rather than clinical. The filter section is genuinely flexible, with four individually addressable poles that can be switched between lowpass and highpass modes, letting you emulate everything from Moog-style resonance to bandpass filtering to acid squelch. Two LFOs per voice handle modulation duties, and the real magic happens in the routing matrix: sixteen sources can be patched to fifteen destinations across four flexible routing paths, with each connection controlled by an electronically managed modifier knob. You can modulate modulations, cross-modulate between voices, and ring-modulate oscillators in ways that would normally require a room-sized modular system.

The front panel is densely packed with forty knobs and buttons, each one directly controlling an important function, plus a 48-character LCD display with soft controls for menu diving. Memory holds 350 single patches and 150 multi-patches, with four wavesets of 248 waveforms each stored internally, and a PCMCIA card slot for loading additional waves and sounds. MIDI implementation is comprehensive, with most parameters controllable from external gear.
