Turn Your iPhone Into A Hardware MIDI Controller

Line 6 has introduced a new $5.99 app, MIDI Surface (App Store link), that lets you turn your iPhone, or iPod touch into a hardware MIDI control surface.

MIDI Surface works with the Line 6 MIDI Mobilizer, a MIDI adapter that connects to the iPhone or iPod touch.

This is pretty interesting – but adapt this for the iPad and get third-party app support and MIDI Mobilizer could become a new platform for musicians.

Details below.

Control Surfaces:


  • Channel
  • Velocity


  • Channel
  • Controller (Mod Wheel, Channel Volume, Expression, etc.)
  • Low Value
  • High Value

Drum Pads

  • Channel
  • Category (Note On, Controller, Program Change)
  • Note
  • Note Off (Immediate, Touch Up)
  • Velocity

X-Y Control

  • Supports up to 4 touches
  • Channel
  • Controller
  • Left Value
  • Right Value

Each interface can be configured with detail and you can save Presets for quick recall.

  1. I was going to ask the same question… I remember one drum machine app that used the built-in mic of the iPhone (but not iPod Touch) to give some velocity-like distinction. Don't know how this one works (and the links indicate its from AudioFile, not Line6…)
