Chords Pad

Chords Pad is a versatile music app for hearing chord tones and visualizing them on a keyboard. It offers three UIs: Pad (Chord List), Custom Pad (large tappable buttons with editable chords), and Chord Progress (auditions of common chord progressions). Tap a chord to hear it and see the chord tones displayed on the keyboard.

• Keyboard range: C2–C7 with playable notes and swipe-to-slide support.
• Bluetooth MIDI support and MIDI note on/off messages.
• 28 chord sounds available (9 initially; full set and tensions unlocked via In-App Purchases).
• Features include chord reordering, visibility toggles in the Chord List, and root-shifted progressions.
• Optional in-app purchases unlock all patterns and tensions (b9, #9, 11, #11, b13, 13, etc.).

If you’d like to expand capabilities such as large-keyboard play or chord progression creation, the app references the Android counterpart for broader chords.
