Interval Based MIDI Keyboard

• In Theory is an interval-based MIDI keyboard app. It has a keypad at the bottom which plays the notes in the scale you are working on.

  The keypad buttons are like +2, +1, 0, -1, +2 where;

  • - The 0 button plays the current note in the scale
  • - The +1 button plays the note after the current note in the scale
  • - The -1 button plays the note before the current note in the scale
  • - The +2 button plays two notes after the current note in the scale and so on.

In Theory has more than 110 scales that you can work on.

You can also use your custom scales that you created in ScaleBud 2!

MIDI Controller Support

• In Theory has MIDI controller and MIDI CC support.

  You can play In Theory with a MIDI Keyboard.

  • - The middle C4 key on your keyboard will trigger the 0 (root) button on the keypad
  • - The white keys after the C4 key on your MIDI keyboard will trigger the positive buttons on the keypad
  • - The white keys before the C4 key on your MIDI keyboard will trigger the negative buttons on the keypad

  You can toggle the chord intervals with MIDI CC. Assign a MIDI CC number and MIDI channel to chord intervals on the settings menu. You can send a MIDI CC value between 0-62 and toggle the intervals respectively.

  You can also sequence In Theory with a MIDI sequencer app such as PolyBud, ShiftBud or MelodyBud.
