Isotope MIDI Keyboard1.1.8 - App Store

Isotope is an isomorphic MIDI keyboard app for iOS.

Isotope makes playing music fun and intuitive, while also making music theory more accessible.

Unlike traditional keyboard, Isotope's isomorphic grid layout is based on mathematical and geometrical properties of sound itself. When you play it, it's much more intuitive. When you want to learn about music, it shows how notes relate to one another.

# Isomorphic Keyboard
- If the interval stays the same, the form of your hand stays the same. For instance, when you put your first finger on the C, third finger on the E and the second finger on the G, it's the C major chord. Now that your fingers are in a triangle, if you just go up by one row, now it becomes the F major chord.
- Square-based isomorphic keyboards like Isotope resembles stringed instruments tuned in perfect 4th apart from one string to the next. Therefore, if you have an experience in playing stringed instruments like the guitar, the bass, the violin, or the cello, you will get learn to play Isotope quickly.
