The Modal Electronics Cobalt 8 is an eight-voice Extended Virtual Analogue synthesizer that embodies the perfect balance between familiar analog warmth and modern digital precision. Housed in a compact yet reassuringly weighty chassis with a striking cobalt blue aluminum front panel, this instrument delivers a mature, sophisticated approach to synthesis that prioritizes musical playability over complexity.
At its heart, the Cobalt 8 features a carefully curated collection of 34 oscillator algorithms that go far beyond traditional analog waveforms. While the first algorithm provides classic sine, triangle, saw, square, and pulse waves with smooth morphing capabilities, the remaining algorithms offer an expertly crafted selection of wave-shaping, sync, ring modulation, and fractal synthesis options. Each algorithm provides two thoughtfully chosen parameters that offer maximum musical impact without overwhelming complexity.
The synthesizer's sound architecture centers around 64 oscillators organized into two independent groups, with voices capable of utilizing up to eight oscillators each. Four distinct play modes - Monophonic, Polyphonic, Unison, and Stacked - provide flexibility from fat mono leads to lush eight-voice polyphony. The innovative "Drift" control adds organic analog-style pitch instability, while "Width" spreads voices across the stereo field for enhanced spatial presence.
The four-pole morphable ladder filter offers multiple configurations including resonant and balanced modes, with seamless morphing between low-pass, band-pass, high-pass, and notch responses. Three ADSR envelopes and three LFOs provide comprehensive modulation options, supported by an intuitive assignment system that makes programming both immediate and enjoyable.
Built around a premium 37-key Fatar keyboard with aftertouch, the Cobalt 8 feels substantial and professional despite its compact three-octave format. The instrument includes full MPE (MIDI Polyphonic Expression) support, making it compatible with advanced controllers like the ROLI Seaboard for enhanced expressive capabilities.
The onboard sequencer offers up to 512 steps with four animation lanes, while a three-slot effects engine provides 12 different effects with 100 preset combinations. The accompanying Modal App extends functionality with detailed parameter editing and visual feedback.
The Cobalt 8 represents synthesis for discerning musicians who value musical immediacy, build quality, and that ineffable sense of "rightness" that makes an instrument truly inspiring to play.
