TB MIDI Stuff is a new modular MIDI control surface for the iPad.

The app lets you create your own pages, or use the built-in MIDI keyboard (with Arpeggiator, modulation wheel, pitch wheel and accelerometer velocity), the built-in Pads controller (with customizable pads banks, accelerometer velocity, transposition, full velocity mode and repeat mode) or the 16 channels MIDI mixer (pan, volume and mute).

The page editor lets you create your own control pages. It contains some useful stuffs like pasteboard, undo manager, multi selection or z-order managment.

TB MIDI Stuff use CoreMidi : you can use any supported device, like the native WiFi driver or the camera connection kit with an external sound card. Each page can use a different CoreMidi driver.

Controls can use the iPad accelerometer as input (even faders and knobs), in each dimension (X, Y, Z or, for XY Pads, a mix of them).

The application library contains :

• Rotary sliders
• Horizontal sliders
• Vertical sliders
• Horizontal faders (with different colors)
• Vertical faders (with different colors)
• Mixer knobs (with different colors and flavors)
• Drum Pads
• XY Pads
• Value displayers
• Rounded rects
• Labels

Each control can drive simultaneously multiple MIDI messages like Control Change messages (single 7bits and coarse/fine 14bits), RNP/NRPN messages (7 and 14bits), Pitch Bend messages, Program Changes messages, Note On/Off messages.

You can open up to 32 pages simultaneously. You can change pages with three fingers swipe gesture, manage the pages order, open multiple instances of the same page and change the MIDI Out driver or the MIDI Out channel (or both) without entering the editor for each instance.

Swipe shortcuts (1, 2 and 3 fingers) let you access quickly to the MIDI keyboard, the pads controller or the 16 channels mixer.

TB MIDI Stuff contains some demo pages and 7 pads banks. For the pads banks :

• Default Bank
• Drum Kit (GM)
• Fifth
• Major Chords
• Minor Chords
• Simple Chord Generator
• Velocity
