Italy's first analog synthesizer arrived in 1972 as a curious hybrid—part organ, part synthesizer—from the small Davoli company, and it remains one of the most unconventional monosynths ever built.
The Davolisint pairs two voltage-controlled oscillators with a divide-down architecture borrowed from transistor organs, letting you layer multiple octaves of the same note across a compact 37-key keyboard. Both oscillators generate a single harsh square waveform, but the real character comes from detuning them against each other and mixing different footage combinations using the seven rocker switches on the left panel. You get independent vibrato controls for each oscillator, three selectable rates of portamento accessed either through dedicated switches or by playing specific black keys on the keyboard, and a spring-loaded pitch-bend lever labeled "Extend" that sweeps up a full octave before slowly returning to center. Fine-tuning sliders sit in the middle of the panel for adjusting each oscillator's pitch, while the lower octave of grey keys duplicates all the main controls—a clever design choice that lets you access functions without taking your hands off the keyboard. There's no filter, no envelope generator, and no way to sync the oscillators, which keeps the sound palette deliberately limited but surprisingly expressive for what amounts to a sophisticated organ with attitude.
The Davolisint has earned respect among collectors and experimental musicians for its raw, detuned character and its unusual control layout. It's genuinely rare and increasingly sought after, though its simplicity means it works best as a textural tool or bass generator rather than a traditional lead synth. The build quality is solid, and units that surface in good condition tend to hold their value well.
