Vermona has announced that the PERfourMER MKII synthesizer is now available.

The PERfourMER MKII combines four discrete built 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 the 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 classic structure 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 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 significantly expand the available spectrum of sounds. Another possible interaction is the synchronization of adjacent oscillators. SYNC and FM can be used at the same time.

However, not only the oscillators can be synchronized. In addition, the LFOs can be synced either to each other or to an internal or external (MIDI clock) clock source.

Play Modes

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 achieve expressive, lively 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 also makes a versatile and complex filter bank with four filter sections, four VCAs, four envelopes and LFOs.

Note: Availability is currently limited to Europe. See the Vermona site for demos, dealers and pricing.
