MIDI controller & instrument for iPad

Every scale,
your shape.

Arrange the pads the way your hands think – as strings on a guitar, stacked octaves or only the notes of the scale. Skaleton keeps your shape in every scale and in every key. Learn a melody or chord once, play it anywhere. As a MIDI controller with your DAW and external gear, or with Skaleton's own old-skool sounds+fx.

The Rings

play.

The Grid

lay it out your way – keep it constant or save it differently with every Build

shape.

Two Sticks

bend, sweep and wobble sounds with your thumbs

The Rings

Set the controls for the
heart of the sun root of the skale

LEFT SIDE

The root ring →

The big green center shows the active root note. Pick a different one from the ring to replace it with a new one.

The grid will change right away.

Inside this ring the current Skale or Build is displayed.

RIGHT SIDE

← The interval ring

The intervals in your skale light up. The perfect fifth glows teal — here, mirrored on the root ring, and on the grid.

You can choose intervals, flats, sharps or Quality as button labels.

Pick a root on the left ring. Follow your bass player, find the note on the grid, or look up the key of the song you want to jam along with – one tap, and the whole grid follows.

Then choose the notes on the right ring: tap intervals on or off, or start from one of the 50+ skales that come with Skaleton. Ring and grid change the moment you tap. Made your own? Save it in a Build.

The GRID

Everything in its right place.

Two main ways to lay out the pads:

FIXED → every pad keeps its note, like a fretboard. Stack the octaves, or tune the rows like strings: standard guitar, Drop D, DADGAD, open chords, all fourths or all fifths. Notes outside your skale stay where they are – playable, or muted if you don't want to hear them.

FOLLOW → only the notes of your skale are on the grid. Stack the octaves, shift each row a few skale steps up like strings, or let the skale stretch across the full width of your iPad.

Dm, in D Dorian.

One chord, three shapes.

FIXED → Guitar

standard tuning: strings and frets where your fingers expect them. Notes outside the skale stay playable.

Lefty? Just flip the grid!

FIXED → Perfect fifths

tuned like a cello or violin: wide reach, compact chords.

FOLLOW → Skale only

Every pad is a note that fits. No wrong notes, ever. A Dm chord is played. Both the interval ring and the grid show their respective chord pattern.

TWO STICKS

Music = Math.

Pick a root on the left ring. Follow your bass player, find the note on the grid, or look up the key of the song you want to jam along with – one tap, and the whole grid follows.


Then choose the notes on the right ring: tap intervals on or off, or start from one of the 50+ skales that come with Skaleton. Ring and grid change the moment you tap. Made your own? Save it in a Build.

01

Learn one shape

A chord or a run you learn once works in every key. Move it across the grid and it still fits.

02

Only the notes that fit

Pick a root and a skale on two rings. The grid gives you the notes that belong, and mutes or hides the rest.

03

Controller or instrument

Send MIDI to your DAW or synth. Or skip the computer and play Skaleton Sound straight from the iPad.

A pad grid that thinks in scales.

On the screen

Six things you’ll use every day.

[screenshot: the full Skaleton screen, with rings, grid, CUEs and sticks]

01 · Rings

A root ring and a skale ring

Turn one ring to pick the root, the other to pick the skale. Over 40 skales, from major and the modes to maqamat.

Read about rings →

02 · FIXED / FOLLOW

Two kinds of grid

FIXED keeps every note in place, tuned in fourths, fifths or a guitar tuning. FOLLOW only places the notes of the current skale, so every pad fits.

Read about the grid →

03 · Orientations

stan, jimi, doyle and sam

Standard, left-handed, left-handed and upside down, or everything flipped. Pick the one your hands already know.

Read about orientations →

04 · Builds and CUEs

Save a setup, fire it live

Store root, grid, sticks, sound and FX as a Build. Put Builds in four CUE slots and switch between them while you play.

Read about Builds →

05 · Two Sticks

Two joysticks, one ghost

Map each axis to a CC or pitch bend, with curves, spring-back and hold. Spoolspook can move in on one stick and fight you for it.

Read about the sticks →

06 · Skaleton Sound + FX

A sound of its own

Old-skool wavetable instruments with chorus, tape delay and reverb, right on the iPad. Headphones in and you’re playing.

Hear Skaleton Sound →

Also on board: EQ tilt, so high notes don’t get buried, and note labels as numbers, flats, sharps or intervals.

Connections

Plugs into what you already have.

Skaleton sends standard MIDI: notes, CC and pitch bend. These are typical latencies. Your setup may differ.

USB

1–3 ms

The tightest timing. Use it for drums and live sets.

WiFi

5–15 ms

No cable, Mac or PC. Fine for most playing; busy networks add jitter.

Bluetooth

10–30 ms

Pair and play. Good for sketching ideas on the sofa.

Works with

Logic Pro · Ableton Live · Bitwig Studio · FL Studio · Cubase · Reaper · GarageBand · any app or synth that speaks MIDI
