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. Design your ultimate MIDI controller, save your looks, morph whole layouts, and play anywhere—solo or together. ## Key features - Build custom MIDI controller layouts - Save and recall presets - Perform with motion and snapshots - Real-time collaboration - Smart MIDI setup - Morphing between states ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/tandem-midi-canvas/id6747936331/reviews.md ### 5/5 — Great idea, well made *2025-11-04* Love this concept, way better than TouchOSC nightmares! Also love that there’s option for wired / passthru 🤘 **Developer response:** Thank you so much. I appreciate the feedback. Much more to come! Passthru is wicked fun I agree. Got you 🫡 Best, Mitchell ### 5/5 — Sheeeeesh 🔥 *2025-10-01* I’m an independent rap artist and this app is wild. I set up my own sliders and pads for beats and effects, and it’s way easier than lugging around extra gear. Focus Mode is awesome when I need to fine tune stuff, and I love that I can switch layouts between studio and live shows.The best part is how smooth it connects. Bluetooth, USB, whatever, it just works. I even messed around with Tandem Mode and it feels like my producer’s right there with me. For real, if you make music and want more control without breaking the bank, this is it. Definitely worth $15! Can you add a doughnut knob? 🍩😂 **Developer response:** Thank you so much! I’m thrilled you’re enjoying it. Wow a doughnut knob would be great lol I’ll add it! -Mitchell ### 5/5 — CRAZY for iOS *2025-07-30* This app packs so many powerful features into an iOS app for musicians!

I have many plans for the future. Just you wait 😇 ## Frequently asked questions about Tandem MIDI Canvas ### What is Tandem MIDI Canvas?
