Tandem MIDI Canvas

Tandem turns your iPhone or iPad into a powerful MIDI controller you can design in minutes—then actually trust on stage. Build custom layouts, map anything, save presets, and perform with motion, snapshots, and real-time collaboration.

BUILD ANY CONTROLLER
• Start from blueprints or a blank canvas and add knobs, faders, XY pads, drum pads, buttons/toggles, momentary buttons, endless encoders, transport, and motion (gyroscope).
• Create compact performance rigs, full mixer pages, synth macro panels, or drum racks—then save them as reusable presets.

FAST, CLEAN WORKFLOW
• Smart snapping, responsive grids, spacing tools, and Focus Mode keep editing quick and performance precise.
• Zoom into a single control for accurate takes and fast MIDI Learn.
• Dashboard Hints + a replayable Tutorial Walkthrough help you level up as you go.

LAYOUTS THAT START YOU AHEAD
• Layout Maker includes curated templates (mixers, synth rigs, drum racks, dashboards).
• Layout Assistant (iOS 26+ on eligible devices) can generate balanced layouts from plain-English prompts when Apple Intelligence is available.
• Smart MIDI setup: new components can auto-assign to unused mappings so you stay in flow.

STATE SNAPSHOTS + MORPHING (THE “WHY TANDEM” FEATURE)
• Save up to 8 states of your entire layout (all control values).
• Jump instantly—or use a Morph Driver to smoothly interpolate between states with a single slider/knob.

RANDOMIZATION YOU CAN PLAY
• Map “Randomize” to any button or pad.
• Trigger smart randomization for happy accidents, sound design, and live performance moments.

COLLABORATE IN REAL TIME
• Tandem Mode lets you host or join a session so multiple devices can share and control the same layout together—great for bands, classrooms, and writing rooms.

THEMES THAT PERFORM
• Stage-ready, high-contrast themes plus an improved Theme Manager and redesigned Theme Maker.
• Import/export themes and preset packages to share looks and workflows.

CONNECTIVITY
• USB-C, Bluetooth MIDI, and Wi-Fi options.
• Background processing helps keep MIDI flowing while you work.

WHY IT’S DIFFERENT
Tandem isn’t just “a controller.” It’s a controller builder with performance features you usually only get from hardware: snapshots, morphing, randomization, and collaboration—wrapped in a fast layout workflow you’ll actually stick with.
