PERfourMER MKII — Vermona

Description

The Vermona PERfourMER MKII is a quad analog synthesizer in a rack format. It comprises four independent monophonic synth channels that can be linked or played together in various configurations, effectively yielding four voices or an ensemble of individual instruments. Each channel is built around a classic VCO/VCF/VCA signal path, starting from an analog oscillator with multiple waveforms and a noise source, through a 24 dB/Oct low-pass filter with adjustable resonance, and into a discrete VCA. Modulation options include a flexible LFO and an ADSR envelope generator for VCO, VCF, and VCA, with support for hard-sync and FM interactions between channels. The design supports diverse play modes (monophonic, duophonic, polyphonic) and synchronization between channels, enabling complex textures and layered sounds. Typical use cases include live performance and studio sound design, where a single PERfourMER MKII can function as four separate instruments or as a cohesive four-voice synth. The device offers MIDI control and optional CV/Gate inputs, with individual channel controls for each function, facilitating real-time manipulation and hands-on exploration of subtractive synthesis and evolving textures.
