COBALT8

8 voice extended virtual-analogue synthesiser

Building on the tradition of warm and punchy analogue-style synth sounds, conceived by legendary synthesisers from the past, COBALT8 unlocks the full creative potential of analogue waveforms. This powerful, inspiring instrument reinvents the aesthetics of analogue sounds and invites musicians, producers and sound designers to explore a new era of virtual-analogue synthesiser textures, far beyond the limits of its analogue forefathers. 

On top of the innovative oscillator engine of COBALT8, we added a new morphable 4-Pole Ladder Filter. Combined with Modal’s unparalleled modulation options, an inspiring real-time / step sequencer, the energising arpeggiator, the Premium FATAR 37-note keyboard, MPE, studio-quality effects and MODALapp integration, COBALT8 is the perfect synth for everyone who wants a versatile electronic music instrument to play vintage synth sounds and is eager to enter new sound dimensions.

Eight true polyphonic voices tempt players to lay out wide string or rich synth pad chords, while a monophonic bass or lead patch, played with 64 oscillators can shake the walls of every stadium. And with the avant-garde sound forming features, every synth enthusiast can refine his performance with sounds that no other synthesiser is able to generate.

Analogue Goodness and so much more

Two independent oscillator groups with up to 4 oscillators each generate not only powerful virtual-analogue goodness, but like no other synthesiser before, 34 unique complex algorithms like Sync, Ring Modulation, Waveform Morphing, and many more are available to increase the creative options for new-generation synth sounds. Each Algorithm has a simple-to-use pair of controls selected to suit the particular algorithm or character, providing musicians the power of traditionally complex oscillator modulations or processes spontaneously.

For every synth lover: our 4-Pole Ladder Filter

COBALT8’s newly designed, self-oscillating 4-Pole Morphable Ladder Filter with Resonance injects more warmth and bite. Switch between the four different filter modes, get creative with the Notch filter and form unusual synth textures with the Phasor. Two different characteristics allow to instil a more subtle behaviour or process the sound with sheer raw power. 

Shape your sound

Three flexible audio-rate (2 x polyphonic) LFOs can be routed to a massive amount of destinations using the modulation matrix and sync to internal or external tempo. Three dedicated envelopes for the filter, amp and modulation allow excessive control over dynamics and expression. Switchable envelope types provide greater options to tailor the envelopes for specific sound purposes. COBALT8’s sophisticated 12-slot modulation matrix supports easy assignments of complex modulation routes to keep the sound evolving. Four common modulation routings are pre-set here to free up space for more exciting ideas.

Next generation Sequencer and Arp

The integrated 512-note Realtime / Step Sequencer with four powerful Animation Lanes invites to compose massive and complex melodic patterns. The polyphonic 64-note step sequencer mode enables easy step input for note and animation values. Multiple sequencer trigger modes coupled with the powerful onboard arpeggiator (programmable up to 32 steps) and performance features such as Chord Hold, Inversions, Transpose, Sustain Latch.

It’s about playing

Professional keyboard players will love COBALT8’s rugged steel and aluminium chassis and the premium FATAR 37-note full-size key bed. The keys support channel aftertouch and deliver smooth action to express powerful playing performances. For direct access of the parameters, COBALT8 features 29 endless knobs, 24 buttons and an X/Y joystick for pitch or modulation, and MPE support offers new ways of creative expression for sophisticated performers. 

Polish your patches with studio-grade FX

Reshape your sounds completely with the onboard stereo effects engine. COBALT8 comes with a 3-slot FX engine with in-depth FX programming. To polish the sound, a total of 11 FX algorithms add character and depth, including Chorus, Phaser, Flanger (Pos), Flanger (Neg), Tremolo, LoFi, Rotary, Stereo Delay, Ping-Pong Delay, X-Over Delay and Reverb.

Looking to connect

Set to be played in any synth environment, COBALT8 comes with all physical connections required. Control the synth using USB, monitor with headphones or using the dedicated line outputs, sync with external gear using the full-size MIDI in and out or the 3.5 mm Sync in or outputs and take control of your sound using the built-in Sustain and Expression inputs. By poly-chaining any two COBALT8 devices, the amount of voices is easily doubled to 16 voices and 128 oscillators.

Access all Areas

There is plenty of room to store patch, effects and sequence creations. Out of the box, 300 of the total 500 patches are filled with factory patch banks, carefully programmed by some of the most accomplished sound designers of the world.  One hundred customised effects configurations and sequences can be stored as well to be applied to any sound while performing.

Free MODALapp for immersive sound programming sessions

The free MODALapp brings the comfort of screen-based editing on your computer or mobile device. Available as a standalone app for macOS, Windows, iOS, iPadOS or Android systems and in VST3 and AU plug-in formats it is the perfect companion for synth enthusiasts looking to deep dive to all sound forming and performance parameters to create their own signature sounds, and to backup and manage patches and sequences.
