Design custom MIDI touch control surfaces with ease. Assign gesture bindings, physics behaviors, automation, visual design, and more on the fly. ----- Make your instrument feel like YOU. ULTIMIDI lets you build your perfect controller layout on a free-form canvas. Add faders, knobs, XY pads, buttons, joysticks, step sequencers, and MUCH more, then arrange and connect them together exactly how you want. Advanced Connectivity: - Connect to any MIDI-capable app, hardware synth, DAW, or Bluetooth MIDI enabled device. (Network connectivity features coming soon!) Automation Capabilities: - Hand draw your LFO curves or instantly adjust a step sequencer. ULTIMIDI prioritizes ZERO menus when in performance mode. Set up your automation targets ahead of time, and adjust them instantly with your own UI layout. Powerful control logic: - Need that fader to push to 75% only when button A and button B are pressed at the same time? No problem. - Chain actions, build logic gates, bind global gestures, and sync them all with with an internal or external MIDI clock. - Complex routing is made simple with zero coding knowledge required. Other Goodies: - Keep multiple controller layouts locally or save them to the cloud - Cross platform capabilities - Map anything with an external MIDI controller - Loop your control devices - Show photos / video on your canvas - Much more Designed for YOU, the creative musician who wants to connect all of their gear together for ease of use in performance or studio workflows without kneeling down to the manufacturer's idea of a "convenient" layout. ----- ULTIMIDI is a growing platform empowering musicians with simple to use MIDI tools that pack a punch under the hood. Music production can be a highly technical pursuit. For some of us that's part of the enjoyment of the activity, and for others, we just want to play. ULTIMIDI seeks to find a balance between complex routing / logic behaviors, and a no-code, open canvas interface that is fun and enjoyable to use. So whether you just want a few knobs with custom emoji cursors, or you want to create a full control surface brain to connect your entire studio together, ULTIMIDI does it all. Inject your soul and creative eye into your control surface, without abandoning technical complexity. ----- ULTIMIDI is in active development, we are actively adding in new features and control devices. Any future additions to the standard version or the currently available add-on packs will be automatically applied to purchases made today. Join the touch control movement!
