Tandem turns your iPhone or iPad into a customizable MIDI controller you can actually trust on stage. Build your own layouts in minutes, map them fast, save reusable presets, and perform with powerful features like snapshots, morphing, motion control, and real-time collaboration. Whether you’re producing in the studio, playing live, teaching, or building DJ performance layouts, Tandem gives you a fast, flexible way to create controllers that fit your workflow instead of forcing you into someone else’s. BUILD THE CONTROLLER YOU ACTUALLY WANT Create custom layouts with knobs, faders, XY pads, drum pads, buttons, toggles, momentary buttons, endless encoders, transport controls, and gyroscope-based motion. Start from a blank canvas or jump in quickly with templates for mixers, synth performance rigs, drum layouts, dashboards, and more. Save your setups as presets and reuse them whenever you want. FAST WORKFLOW, BUILT FOR REAL USE Tandem is designed to help you build quickly and perform confidently. Features include: • Smart snapping and responsive grids • Spacing tools for clean layouts • Focus Mode for precision editing • Fast MIDI Learn • Helpful hints and a replayable tutorial walkthrough • Smart MIDI setup so new controls can automatically map to unused assignments SHAPESHIFT YOUR PERFORMANCE This is where Tandem becomes more than a controller. Save up to 8 snapshots of an entire layout, including all control values. Instantly jump between states or smoothly interpolate between them using a Morph Driver. It’s perfect for live performance, evolving sound design, transitions, and expressive macro control. RANDOMIZATION YOU CAN PLAY Map Randomize to a button or pad and generate musical variation on demand. Great for experimentation, happy accidents, sound design, and live moments that feel alive instead of static. COLLABORATE IN REAL TIME With Tandem Mode, multiple devices can share and control the same layout together. Host or join a session and collaborate live across devices—ideal for bands, classrooms, writing rooms, rehearsals, and shared performance setups. Locally and Remotely via SharePlay! DJ AND PERFORMANCE READY Tandem isn’t just for synths and studio control. It can also power performance-oriented layouts for transport, mixing, browser access, FX control, looping, hot cues, waveforms, and more. Build focused pages for the way you actually perform. THEMES THAT LOOK GOOD AND HOLD UP ON STAGE Use high-contrast, stage-ready themes or create your own look. Tandem includes a redesigned Theme Maker plus import/export support for themes and preset packages so you can share setups and visual styles. FLEXIBLE CONNECTIVITY Connect with: • USB-C • Bluetooth MIDI • Wi-Fi Background processing helps keep MIDI flowing while you work. Tandem isn’t just a MIDI controller app. It’s a controller builder with performance features you usually only get from dedicated hardware—wrapped in a workflow that’s fast, modern, and easy to come back to. Design your ideal controller, save your favorite setups, morph entire layouts, and perform anywhere—solo or together.

Gritopia is a character processor built for adding texture, weight, and attitude to any sound. Rather than simply clipping or saturating, Gritopia layers harmonic coloration, evolving instability, and controlled degradation to create rich, expressive character. From subtle warmth to heavily damaged digital grit, every control interacts to produce movement rather than static distortion. The result is an effect that feels alive, constantly shifting as it reshapes your sound. Perfect for drums, bass, synths, guitars, vocals, and creative sound design. Features • Layered saturation and harmonic coloration • Digital erosion and evolving texture • Dynamic instability and motion • Designed for both subtle enhancement and aggressive destruction Controls Grit – Controls the overall amount of texture and saturation. Tone – Shapes the tonal balance of the processed signal. Fuzz – Adds thick harmonic fuzz and aggressive character. Erode – Introduces digital wear, degradation, and broken texture. Drift – Creates slow, evolving movement. Jitter – Adds fast instability and unpredictable variation. Glue – Blends the processed layers into a cohesive sound. Mix – Balances processed and dry signals.
