Key Lens vs TONAUT

Start with a scale. Every chord, note, and progression in the app stays locked to the key you pick. Explore common chord progressions or build your own! Extensive options for voicings, inversions, extensions, borrowed chords, alternate bass notes, and more. Learn to play your chord progression on piano! Easy to read, color coded piano diagrams make playing your chords on a real piano easy.

Tonaut is a synthesizer, drum machine, sequencer and eight-track tape recorder in one instrument, made to be played rather than programmed. Pick a sound, tap out a pattern and record it to tape, all on one panel that feels more like hardware than an app. IPHONE DUO • Folded, one octave on the outer screen.
