"Design the perfect MIDI controller for you.
Imagine the perfect MIDI rig. Create it with MIDI Designer on iPad. MIDI Designer is the ultimate way to control hardware and software synths, effects, and DAWs (like Ableton, Cubase, Reaper, Logic). And, via the "Pedalboards" feature, MIDI Designer is the ultimate hardware-software hybrid.

DESIGN IT
Design it on iPad with MIDI Designer. Switch to performance mode and play it hard. Design again. Repeat until perfect.
• Your rig has the controls you need (knobs, sliders, cross-faders, X-Y pads, buttons) in the sizes you want, arranged in a way that makes sense to you. Put labels on what you need. Organize, reorganize, play.
• Your rig has one page, a few pages, or tons of pages. Mix color and texture for each. Arrange them. Rearrange them.

MIDI UNLEASHED
MIDI Designer breaks through the limitations of hardware:
• Rewind the timeline. Save all current control positions to presets. Instantly recall them later.
• Supercontrols: Set up chains of controls. Have one superknob turn several knobs, or have a superbutton shut off hundreds of buttons in a single touch. The possibilities are endless.
• Copy the same control to multiple pages.
• Save your rig, copy it, share it.
MIDI DESIGNER: USE IT WITH YOUR FEET
Step on MIDI Designer; it was made from the ground up to be used with hardware pedalboards. As pages change, the same hardware controls connect to different controls. You can finally build the infinite virtual pedalboard of your dreams.
MIDI DESIGNER: DESIGN EASY, PLAY HARD
Push it hard and play it hard. MIDI Designer is battle-tested and performance-ready, with sub-5ms end-to-end latency, even over Wifi.
CONNECT
Connect via Wifi to your computer or use any CoreMIDI-compliant hardware connection (CoreMIDI-compliant devices include the Line6 MIDI Mobilizer II, iConnect and iRig).
JUST WORKS
MIDI Designer is the result years of experiments. Now, it just works. In Design Mode it’s flexible and allows you to build your rig quickly, easily, and intuitively. In performance mode, your rig locks down for rock-solid performance.
MIDI Designer’s unique two-up page design lets you mix and match parts of your rig in a flexible, natural way. Knob and Slider Overlays (patent pending) solve the “opaque-finger” problem once and for all. Dozens of other features including page banks and unique-CC note selection allow you to design a perfect rig using MIDI Designer for iPad.
I hope that MIDI Designer will let you express your perfect MIDI controller. It’s time.
MIDI Designer Pro also comes in a fully-functioning Lite version (with limited controls and colors). If you're unsure as to whether you need Pro, check out the Lite version first."
There is a lite version as well.
