Play a chord on a MIDI keyboard and Xascada names it as you press it — the key, the chord and the Roman numeral — while the notes fall as light.
Mac, Windows & iPad
A top bar reads the key, the chord and the Roman numeral in real time, so a voicing you found by ear gets its name the moment you hold it.
Beside the numeral, Xascada points to a related key — parallel, relative, subdominant or dominant — so you can see where the harmony could move.
When a progression works, build on it in Compose: a chord heat-map with weighted suggestions, then export MIDI or send it to practice.
One bar across the top of the window, updated live: the key you're in, the chord under your hands, and its Roman numeral in that key. After them, an arrow points to a related key and names the relationship — parallel, relative, subdominant or dominant. The tempo control sits beside it.
Play a progression and watch it name itself. The notes you're holding fall as light onto a lit keyboard below, so you see the voicing and its name at the same moment.
Chord recognition works from MIDI — the notes your keyboard sends — so there is no microphone to place and nothing to calibrate.
Theory students checking their Roman numeral analysis against what their hands are actually doing. Songwriters who found a chord by ear and want to know what to call it. Teachers who want a progression's numerals on screen while they play it. Producers sketching a part who want the harmony named before they commit it.
Compose takes over where reading stops: build a progression from a chord heat-map with weighted suggestions and templates, reorder it by drag, then export it as MIDI to your DAW or send it to practice and drill it.
Any standard MIDI keyboard or controller — 25 keys to 88, weighted or not. USB MIDI, plug and play. Xascada lists every connected device.
Yes. The top bar reads the Roman numeral of each chord in the current key, and points to a related key: parallel, relative, subdominant or dominant.
No. Recognition works from the MIDI notes your keyboard sends, so it needs a MIDI connection rather than a microphone.
Yes — Windows 10 or 11, 64-bit, or macOS 12 or later, Apple Silicon and Intel. On iPad it's on the App Store (iPadOS 17 or later, with a USB or Bluetooth MIDI keyboard).
Every plan starts with a 14-day free trial with the whole instrument, live chord reading included. Cancel before it ends and you pay nothing.
Free for 14 days on Mac, Windows and iPad. Plug in and play a chord.
