Modal Electronics' 5-voice extended virtual analog synthesizer is here.

Modal Electronics’ USB-powered COBALT5S is made to move and ready to spark your creativity wherever, and whenever, inspiration strikes. It’s founded on next-generation COBALT synth architecture and housed in an ultraportable go-anywhere footprint. Whether it’s a singularly authentic replication of classic analog sounds, or the most contemporary texture, COBALT5S’ extended virtual analog sound engine delivers on all counts.

COBALT5S takes inspiration from the iconic sound of its analog forebears, transcending any and all limitations to take a leading-edge synth architecture truly mobile. From sultry basslines to expansive, mutating beds—and everywhere in between—COBALT5S is not just modeling run-of-the-mill analog sounds, this is beyond analog, anywhere.

Create without limitation

Featuring five true polyphonic voices, two independent algorithm groups and up to eight oscillators per voice, musicians, sound designers and producers are armed with a palette of sound that’s primed for any application imaginable. Fuse this with 40 complex algorithms, including Sync, Ring Modulation, Waveform Morphing plus many more, and it’s easy to see how COBALT5S empowers creators with liberated sound-sculpting capability without limitation.

Ear candy

Featuring the self-oscillating 4-Pole Morphable Ladder Filter from the COBALT8, COBALT5S guarantees to texture your sound with all the bite and warmth your performance demands. Four separate filter modes fuse with mainstay controls for cutoff and resonance, alongside a morph parameter to musically manipulate the frequency response of the filter for a truly immersive experience. From the sublime to the experimental and everywhere in between, crafting the perfect timbre is limited only by your imagination.

Sound shaping, simplified

Everything you demand to craft the perfect sound in meticulous detail is right at your fingertips with COBALT5S. Three envelopes with selectable types take command of the filter, amp or modulation destinations, empowering you with unrestricted options when it comes to fine-tuning your sound. One polyphonic LFO and one global LFO provide extended power to control a plethora of modulation sources, selected via a sophisticated 8-slot modulation matrix. Whether it’s an otherworldly evolving soundscape, rhythmic pads or a searing lead, realizing your creative vision has never been this easy.

Made to move

Taking the legendary build quality synonymous with Modal Electronics’ synthesizer roster and outfitting this with a 37-note compact keybed with aftertouch, COBALT5S is primed for your creative exploits wherever and wherever creativity strikes. Plus, with a USB powered specification, powering the COBALT5S from your Mac, PC or portable power brick couldn’t be any simpler.

Control, evolved

Take complete command and craft your signature sound with ease, courtesy of 16 switched encoders. For complete expressive capability, COBALT5S’ X/Y/Z touchpad provides ultimate 5-axis control over pitch bend, mod wheel and/or any user-selected modulation assignment. Two independent stereo effect engines, including delay and chorus, inject depth and character into your patches, allowing you to create polished synth textures. Rounding out this tactile, performance-centric control assortment is a radiant monochrome OLED display that relays all key information you demand in razor-sharp resolution.

Connection options

Integrating COBALT5S into your existing setup couldn’t be simpler. Connect to PA systems, stage boxes, mixing desks and more with dual 1/4" line out jacks. Practice in private thanks to a 1/4" stereo headphone output. Add some genuine piano-style sustain to your performance with a 1/4" sustain pedal input. Connect to all your MIDI peripherals thanks to full-size MIDI ins and outs, as well as MIDI over USB capability. Finally, keep everything on point with COBALT5S’ clock sync in and out. Whatever your next performance demands, COBALT5S assimilates with ease.
