Imagine having four independent analog synthesizers right at your fingertips, each capable of weaving its own sonic thread into a rich tapestry of sound—this is the magic that sets the PerFourMer MKII apart in Vermona's lineup of hands-on analog gear.
Each of its four channels packs a genuine analog VCO offering sine, triangle, two squares, two sawtooths, pulse width modulation, and white noise, feeding into a punchy 24dB/octave low-pass filter with resonance. Modulation comes from a dedicated LFO per voice—saw down, square, sine, or sample & hold, syncing to MIDI clock—and a full ADSR envelope that shapes pitch, filter cutoff, and VCA. Hands-on knobs give direct access to every parameter, with per-channel external inputs for filterbank duties, individual mono outs plus stereo mix with pan, a headphone jack, and optional CV/gate for modular integration. Housed in a sturdy 19-inch 5U rackmount chassis weighing about 3.7kg, it supports six play modes from monophonic unison to polyphonic, plus FM and hard sync between voices for endless experimentation.
Players love its intuitive layout that rewards tweaking in real time, delivering thick basses, soaring leads, and experimental textures with zero menu diving—though some wish for built-in wooden side panels.
