VIEW MODES

Switch between six layouts from the View menu:

Piano: a familiar 2-octave keyboard with height-based velocity.
Piano Fader: four CC faders in place of the XY pad and drum pads. Assign any CC to each fader and save CC sets as presets.
Grid: Isomorphic: every row and column keeps the same interval, so chords and scales have one shape anywhere.
Grid: 2 Rows: a piano-style pair of rows, naturals below, sharps above.
Grid: Minor Thirds: columns step up by 3 semitones, rows move chromatically.
Grid: Big Piano: large naturals with quarter-size sharps.

Your view, layout, and root note persist across sessions.

SCALE MODE

Choose from 12 scales - Major, Natural Minor, Harmonic Minor, Melodic Minor, Dorian, Phrygian, Lydian, Mixolydian, Locrian, Pentatonic Major, Pentatonic Minor, Blues, and Whole Tone - in any of the 12 root keys.

On the grid, cells remap so only in-scale notes are laid out, putting every note under your fingers.

On the piano, the keyboard keeps its familiar black and white pattern. Out-of-scale keys dim and stop responding to touch, so only the keys in your key are labelled and playable. Switch back to Chromatic anytime for the full keyboard.

GRID EXPRESSION

Every grid layout includes a dedicated mod-wheel row. A vibrant gradient highlights roots and notes, optional labels show note names, and per-note MPE with pitch bend gives each finger independent control.

BUILT-IN SOUND ENGINE

Play sounds without any external app. Load SF2 SoundFonts with multi-preset selection, or import SFZ, WAV, and M4A samples. The low-CPU engine maps samples across the keyboard automatically, and sounds persist across sessions.

AFTERTOUCH & MPE EXPRESSION

Mono AT applies uniform pressure across chords, Poly AT sends independent pressure per note, and XY MPE allocates per-note MIDI channels (2-16) with Y on CC74 and X on Pitch Bend. Remap aftertouch or mod wheel to any MIDI CC or Pitch Wheel. A green gradient on pressed keys shows pressure in real time.
