We hash the visible text on every check, so a redesign registers and a rotating advert does not. An app that has not changed in a long time is not necessarily abandoned — but it is a fact worth knowing before you depend on it.

What it does

Connect a MIDI keyboard or a MIDI-capable phone app, then pick a genre, scale, key and level. Notes and chords fall from the top of the play area and you play each one in time before it lands. The genre sets which progressions and scales you get: pop and classical stay in major and minor, rock and blues add mixolydian, jazz and funk add dorian, and EDM adds phrygian.

What people say

We would rather show none than invent them.
