In fact, the PERfourMER MKII consists of four full-fledged monophonic analog synthesizers (synthesizer channels), which you can combine with each other in any way you like in order to create extraordinary but also classic timbres.

The Synthesizer Channel
The analog oscillator with five waveforms and the noise generator generate the output material, which then passes through the musical 24 dB low-pass filter with adjustable resonance before being shaped in volume by the discrete VCA. Modulation sources are the extensively synchronizable LFO and the envelope generator with the control options Attack, Decay, Sustain and Release. This alone allows you to effortlessly create a wide spectrum of the most varied sounds of the highest quality ... to make it as easy as possible for you on this sound journey, the PERfourMER MKII has a separate control for each function!

The combination makes the difference
The PERfourMER MKII shows its true potential when you combine several synthesizer channels with each other: whether with mutual frequency modulation or synchronization, the PLAYMODE or best of all everything together. The possibilities are endless and you decide whether you want to use the PERfourMER MKII as a four-voice synthesizer or as an orchestra of individual instruments.

Digital or analog control
The PERfourMER MKII is equipped with a MIDI interface as standard. Do you prefer an analog sequencer with CV and gate outputs? No problem, we can optionally equip your PERfourMER MKII with the corresponding inputs ex works.


Synthesizer Channel

  • an analog oscillator with sine, triangle, square and sawtooth waveforms, noise generator (white) and external audio input
  • Pulse width modulation of square waveform by LFO and MIDI (Modulation wheel CC#1)
  • a resonant low pass filter with 24 dB/octave
  • an LFO with sawtooth (falling), rectangle, sine and sample & hold
  • an ADSR envelope generator for VCO (pitch), VCF and VCA

Interaction of synthesizer channels

  • VCO and VCF frequency modulation
  • Oscillator synchronization (Hardsync)
  • Operating modes for connected synthesizer channels:
  • M1 - monophonic
  • M2 - rotating
  • D1 - duophone, unisono
  • D2 - duophone, rotating
  • P1, P2 - polyphonic


  • Power supply: integrated power supply (90 V~ to 240 V~)
  • Dimensions: Approx. 43,5 cm x 31,5 cm x 11 cm
  • Weight: approx. 3.7 kg
  • Rack angle included in delivery

Optional accessories:

  • CV/Gate inputs (can only be retrofitted by Vermona)
  • wooden side panels
