CARBON8M

8-Voice Experimental Synthesizer Module

Step beyond everyday synth experiences and enter the bold, electrifying world of contemporary sound design with the Modal Electronics CARBON8M. This powerful 8-voice synthesizer module redefines sonic exploration, offering groundbreaking ways to create, experiment with, and perform next-generation sounds. Featuring a sound engine twice as intricate as the popular ARGON8 and COBALT8 series, CARBON8M integrates complex waveform algorithms and cutting-edge wavetables into a premium 8-voice architecture—complete with advanced filter technology and dynamic LFO capabilities.

To match its revolutionary sound engine, CARBON8M delivers a wealth of creative tools: deep modulation options, an inspiring real-time / step sequencer, a high-energy arpeggiator, expressive MPE support, studio-grade effects, and seamless integration with MODALapp. Its compact design adapts effortlessly to your setup—place it on a desktop, or mount it into a 19" rack with the included rack ears.

Revolutionary Sound Engine

At the heart of CARBON8M are two powerful oscillators, each powered by 56 cores. These generate a selection of 18 high-resolution algorithms and 38 unique wavetables, delivering a vast sonic palette—from aggressive, cutting-edge textures to warm, lush timbres.

Each patch allows any combination of two algorithms or wavetables, and with a single macro parameter, you can easily sculpt and explore rich harmonic variations and tonal sweet spots.

Advanced Modulation

Dive deep into creative control with a comprehensive modulation section. Three flexible LFOs offer waveforms like variable pulse width, variable-slope triangle, and dual-rate ramps.

Three Envelope Generators (EGs) provide precise modulation over pitch, filter, and amplitude. With 12 modulation slots, you can route sources and destinations freely to warp and animate your sound in endless ways.

Mangle and Tweak

The XCore Oscillator Modifiers open up advanced sound-sculpting options. Apply Phase Distortion, Wavefolding, and Waveshaping to craft everything from subtle harmonics to radical transformations—ideal for forging new and experimental textures with character and depth.

34 Filter Types to Shape Your Tone

CARBON8M features a vast filter section with 34 different filter types, ranging from vintage analog-style circuits to modern Modal-designed innovations.

Many filters include Drive and Morph parameters, enabling subtle tonal enhancement or extreme sound manipulation—perfect for everything from classic subtractive synthesis to far-out sound design.

Bring Your Patterns to Life

The powerful built-in 512-note real-time/step sequencer features four independent animation lanes for complex, evolving performances. Use polyphonic step sequencing to enter notes and automation data with ease.

Multiple trigger modes, a programmable 32-step arpeggiator, and performance-ready features like Chord Hold, Inversions, Transpose, and Sustain Latch make CARBON8M a powerful tool for both the studio and the stage.

Full MPE support unlocks next-level expressive control for compatible controllers.

Studio-Grade FX Engine

Shape your sound to perfection with CARBON8M’s 3-slot stereo-FX engine. Choose from 26 studio-quality effects including lush reverbs, spacious delays, warm chorus, immersive phasers and flangers, plus tremolo, lo-fi, rotary speaker, EQ, compression, and more. Each effect is fully programmable for detailed sonic customization.

Built for Any Setup: Desktop or Rackmount

CARBON8M is built into a rugged steel and aluminum chassis that speaks to its professional intent. Its compact form factor is perfect for desktop use, while included rackmount ears allow seamless integration into a 19” rack.

With 13 switched encoders, 13 endless encoders, 9 responsive buttons, and an X/Y joystick, it offers intuitive hands-on control for real-time sound shaping.

Extensive Connectivity

Designed to fit into any workflow, CARBON8M includes USB and 5-pin DIN MIDI I/O, headphone and line outputs, 3.5mm sync in/out, and inputs for sustain and expression pedals.

Need more voices? Poly-chain two CARBON8 units to expand to 16 voices effortlessly.

Hundreds of Inspiring Patches

Out of the box, CARBON8M comes loaded with 300 expertly crafted factory patches, with space for up to 500 total user patches. Additionally, you can store 100 custom effects presets and sequences for instant recall—perfect for live sets or on-the-fly experimentation.

MODALapp Integration

Take full control of your sound design with MODALapp, a powerful cross-platform software editor and patch manager that provides deep editing capabilities and effortless library organization.
