Positive Grid Launches Project BIAS X: AI-powered Guitar Tone Platform

Positive Grid Launches Project BIAS X: a Premier AI-Powered Platform for Guitar Tone Creation. From concept to mix-ready sound in seconds, this first-of-its-kind software tool transforms how musicians create and shape tone.

Positive Grid introduces Project: BIAS X, a ground-breaking AI-powered guitar tone platform (Mac/PC) that transforms the way guitarists and producers can craft, explore, and refine sound. Designed for fast inspiration, expressive realism, and unmatched flexibility, BIAS X blends cutting-edge AI with a next-generation tone engine to deliver a first-of-its-kind workflow.

BIAS X is the first fully generative, guitar tone design software tool powered by Agentic AI, enabling musicians to move from abstract idea to mix-ready tone within moments. From subtle finger dynamics to soaring leads; from punchy modern metal to dreamy ambient swells, BIAS X delivers highly detailed, authentic tones that embody the analog character of tubes, speakers, and circuits. The result is tone that feels as real as it sounds—present, powerful, and deeply expressive.

Whether running standalone for tone exploration or as a DAW plugin for recording, BIAS X helps musicians spend less time tweaking and more time making music.

A Paradigm Shift in Tone Creation

For decades, creating new tones meant navigating through layers of gear, menus, and manual tweaks. Now, musicians can just say what they want. Powered by Agentic AI* that understands tone like a musician, BIAS X transforms user input into high-quality sounds fast—making tone creation feel less like trial and error, and more like inspiration.

Text-to-Tone: Create tones from descriptive prompts such as favorite artists or songs, genre styles, or even abstract feelings.
Music-to-Tone: Upload audio clips to recreate tones via real-time AI analysis.
AI Refinement: Request live edits like “more bite,” “less fuzz,” or “add crunch.”

This agentic AI workflow simplifies tone discovery while enabling deep customization. Users can accept the AI's creation or dive in for manual, real-time tweaking.

Built for Response and Fidelity

An all-new BIAS X tone engine combines Positive Grid’s deep expertise in amp and effects modeling with the latest in machine learning and circuit-level modeling. It goes far beyond traditional tone modeling—reproducing the physical behavior of analog gear and the complex interactions between tubes, circuits, and speakers. The advanced Agentic DSP engine ensures that every note cuts through with clarity and punch, preserving harmonic richness across all playing styles. The result is the unmistakable feel and dynamic response of real hardware, now supercharged and infinitely flexible.

200+ Amps Learned: The circuits, transformers, and tonal behavior of over 200 amps were analyzed to understand what makes legends legendary and enable users to create with that same depth and precision.
Adaptive Circuit Modeling: Feels alive when guitarists play, reacting to their pick, dynamics, and volume like a real tube amp.
Harmonic Fingerprinting: Keeps the unique harmonic details that define each amp’s character.
Power Amp Saturation: Recreates the natural compression and distortion of real power tubes, for a rich, 3D tone.

Amp, Cabinet and Effects

BIAS X is a complete tone playground with 33 amps, 63 effects, IR Loader, and new cabinets that capture the feel of legendary gear alongside Positive Grid’s modern sound design. Craft tones manually or use AI-assisted tools for fast, inspiring results.

33 Advanced AI-powered Amp Models: The advanced sound engine analyzes preamps, power amps and transformers with AI-enhanced precision. It captures circuit-level dynamics like transformer sag and power amp response to deliver models with authentic compression, harmonic richness, and dynamic response that traditional modeling can’t match.
63 Versatile Effects: Built with component-level modeling. Each effect utilizes Agentic DSP trained on vintage analog gear to recreate the subtle non-linear behaviors and dynamic sensitivity that give classic pedals their distinctive character.
All-New Cabinet Simulation: Developed by Positive Grid engineers and in partnership with Spectre Digital, featuring high-fidelity IRs of legendary cabs and mics.
IR Loader: Load and blend two custom user IRs for flexible, fully tailored cabinet tones.
Build Anything: Mix and match any amp, cab, and effect to create a custom dream rig.

Designed for Fast Flow

The redesigned drag-and-drop interface is intuitive and clean, eliminating the menu-diving and knob-fiddling that break creative flow. Users can enjoy a streamlined workflow for crafting personalized tones quickly and easily. Or, they can go deeper with powerful features that enable confident experimentation while creating custom signal chains and more complex sounds.

Dual Signal Chains: Split the signal and process it in two parallel paths—each with its own effects. Stack or pan them for wide, layered, or contrasting tones.

Drag-and-Drop Workflow: Rearrange amps, cabs, and effects visually and instantly—build a chain in seconds.
Streamlined Preset Manager: Organize and recall tones fast with an overhauled interface built for clarity.
Flexible Routing Matrix: Experiment with parallel paths, stereo splits, and creative FX placement. Turn on the global Doubler effect to double the signal for added width.
Smooth Real-Time Control: BIAS X offers an intuitive, easy-to-use signal path interface. Move components horizontally or toggle them vertically to adjust gear placement on the fly.
Revamped Gear Browser: Browse, compare, and swap gear with a faster, more intuitive experience.

A Platform That Evolves

Built on agentic AI, BIAS X is designed to adapt and evolve along with musicians, offering a living platform full of realism, responsiveness and nearly-endless customization.
