Vermona PerFourMer MKII

The PERfourMER MKII will be available worlwide in December - and the first units have already been shipped to Europe this past week.

“Four combinable synthesizer in one.” That’s the short description of the PERfourMER’s concept. The MKII-version comes with additional functions and a new user interface designed to offer more space and clarity.

The Concept

PERfourMER MKII combines four monophonic analogue synthesizers into a single rack-mountable, desktop unit. The individual synthesizer channels can be coupled in different ways and be played monophonically and polyphonically. At he same time, the synthesizer channels can interact by using oscillator synchronization or frequency modulation.

The Synthesizer Channel

All four synthesizer channels are based upon the cstructure of VCO, VCF and VCA. The oscillator offers sine, triangle, square and saw tooth waveforms or a noise generator. In addition, the square waveforms’ pulse width can be modulated using a LFO or MIDI control data.

The following resonant low-pass-filter offers a steepness of 24 dB per octave and is being followed be the voltage controlled amplifier (VCA).

A flexible LFO and an ADSR envelope generator are designed to 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. For example, a frequency modulation of oscillator or filter will expand the available spectrum of sounds. Another possible interaction is the synchronization of adjacent oscillators. SYNC and FM can also be used at the same time.

The oscillators can be synchronized, and in addition, the LFOs can be synced either to each other or to an internal or external (MIDI clock) clock source.

Playmodes

PERfourMER MKII’s voice assignment allows choosing between six operational modes. Coupled synthesizer channels can either be played polyphonically, duophonically or monophonically. This way, you can achieve sequences that may use a rotating voice assignment where each note addresses an individual synthesizer channel.

Filter bank

Each synthesizer channel offers its individual input that replaces the oscillator waveform as sound source. This way, PERfourMER MKII can also be used as a filter bank with four filter sections, four VCAs, four envelopes and LFOs.
