Vermona PERfourMER MKII CV/Gate Quad Analog Synthesizer
Vermona's original PERfourMER has long been admired, both conceptually and for its unique sound. Always iterating on their successful synthesizer designs, Vermona added a few extra ingredients and a little more spice and cooked up PERfourMER MKII — give it a try!
PERfourMER MKII combines four discrete built monophonic analog synthesizers into a single rackmountable desktop unit. What sounds simple will surprise you with its large sound variety. The individual synthesizer channels can be coupled in different ways and played monophonically or polyphonically. At the same time, the synthesizer channels can interact with one another via oscillator synchronization or frequency modulation.
The synthesizer channel
All four synthesizer channels are based upon the classic structure of VCO, VCF and VCA. The oscillator offers sine, triangle, square and sawtooth waveforms or a noise generator. In addition, the square waveforms' pulse width can be modulated using a LFO or MIDI control data. The resonant low pass filter that follows offers a slope of 24 dB per octave and is followed by the voltage controlled amplifier. A flexible LFO and an ADSR envelope generator allow for modulations of the oscillator's pitch as well as the filter's cutoff frequency.
FM and sync
PERfourMER MKII's synthesizer channels can interact with one another. For example, a frequency modulation of oscillator or filter will significantly expand the available spectrum of sounds. Another possible interaction is the synchronization of adjacent oscillators. SYNC and FM can even be used at the same time! However, it's not just the oscillators that can be synchronized: in addition, the LFOs can be synced either to each other or to an internal or external (MIDI) clock source.
PERfourMER MKII's clever voice assignment lets you choose among six operational modes. Coupled synthesizer channels can be played polyphonically, duophonically or monophonically. This way you can create expressive, lively sequences that may use a rotating/cycling voice assignment where each note addresses a successive individual synthesizer channel.
Each synthesizer channel has an external audio input to replace the oscillator waveform as sound source. This way, PERfourMER MKII also makes a versatile and complex filter bank with four filter sections, four VCAs, four envelopes and four LFOs.
Belying its immense flexibility, PERfourMER MKII was carefully designed to be used effortlessly and in a straightforward way. Its no-compromise, hands-on, direct-access design to all relevant parameters was an imperative for the development team at Vermona.
