Tiny Instrument 2.3
Chord Lab turns one finger into a full chord, the progression editor lets you play a progression straight in and pick from a circle of fifths, and Two-Hand Drills build hand coordination from any key.
Chord Lab
One finger. A full chord.
Press a single key and hear a complete chord. Switch types, stack extensions, and let Key Mode keep every chord in your key — on screen or from your MIDI pads.

Progression editor
Play a progression straight in.
Capture chords from your MIDI keyboard, pick from an interactive circle of fifths, and read the whole progression by colour.
Two-Hand Drills
Each hand, then together.
Theory-generated coordination drills from any key — scales over a bass drone, contrary motion, walking bass, and arpeggio splits.
Chord Lab
A new chord instrument in Play: press one key, hear a full chord.
Full chords from one key
Press any key and hear a complete chord instead of a single note. Choose major, minor, suspended, or diminished — the four base types and a bass voice are free forever.
Extensions, Key Mode, and voicing
Stack extensions — 6, m7, Major 7th, and 9 — for richer sevenths and added-note chords, let Key Mode auto-generate the right in-key chord as you play, and walk through inversions for smooth voice-leading.
Play it from your pads
Map your MIDI controller's pads to the chord buttons, or use the on-screen bar so it works without any hardware.
A faster progression editor
Build chord progressions in Compose by playing them in, picking visually, and voicing every chord.
Play it in
Tap Listen and play chords on your MIDI keyboard — each one is detected and added as you release it, with a live preview of the chord you're holding. Chords that belong to your key show their Roman numeral.
Pick from the circle of fifths
On the Mac, the chord picker includes an interactive circle of fifths. The chords in your key are lit and labelled; tap any wedge to add it, and the names follow your sharp or flat preference.
Colour-coded harmony
Every chord reads by colour — major blue, minor purple, diminished orange, and out-of-key green — across the editor, Play, and Chord Lab.
Voice every chord
Step through inversions or set a slash bass; the chord name, the keyboard preview, and the sound all update live as you re-voice it.
Also in 2.3
More across practice, MIDI, and the whole app.
Two-Hand Drills
A new practice mode for hand coordination: scales over a bass drone, parallel and contrary scales, chords with a walking bass, and arpeggio splits — generated from any key, practiced each hand then together with bronze, silver, and gold tiers.
Multiple MIDI inputs
Activate more than one MIDI controller at once, with a per-device on/off list in Settings and a quick toggle in the bottom bar.
Do-Re-Mi note names
Switch note names to fixed-Do solfège and every keyboard, staff, and chord label follows along — with your choice of Si or Ti for the seventh.
Explore chords with Quick Chords
The Play Quick Chords strip follows the same colour-coding as the progression editor, so the key's chords read at a glance.
