MidiCore™ — Music Has No Disability

The Story Behind MidiCore

When the luthier himself lives with disabilities, the instrument adapts — not the musician.

Multi-Dys Engineer-Luthier · Dyslexia · Dyspraxia · Neurodivergent

Ewen d'Aviau — A Luthier Who Understands

Trained in lutherie, driven by personal experience with invisible disabilities.

Ewen lives with dyslexia and dyspraxia. He trained as a luthier and created adapted instruments — the Octodyna, metamaterial speakers for deaf musicians. He has collaborated with the Philharmonie de Paris and CNSM de Paris.

Multi-dys: designs from lived experience with motor & cognitive challenges
Created the Octodyna — an inclusive instrument for all abilities
Metamaterial speakers: deaf musicians feel sound through vibration
Collaborated with Philharmonie de Paris & CNSM de Paris
Every accessibility module is tested on himself first

3 Exclusive Accessibility Modules

No other MIDI system offers these. Because no other designer needed them personally.

Note Stabilizer · Anti-Tremor Filter

Note Stabilizer (Anti-Tremor)

Involuntary presses vanish. Only intentional notes reach the sound.

Filters presses shorter than 150ms, ignores adjacent accidental keys, stabilizes velocity variations, and provides real-time statistics so therapists can track progress.

Filters involuntary presses < 150ms automatically
Ignores adjacent key accidents from tremor spread
Velocity stabilization — consistent dynamics despite tremor
Real-time statistics for clinical tracking

For: Parkinson's, essential tremor, dystonia, cerebral palsy, MS, post-stroke, arthritis

Assisted Hold · Anti-Fatigue System

Assisted Hold (Anti-Fatigue)

Press once — the note sustains by itself. Save your energy for the music.

Five hold modes adapt to every condition: Latch (toggle on/off), Timed (100ms to 10 seconds), Next-note (holds until the next key), Infinite (never stops), and Disabled (normal play).

Latch mode — toggle notes on and off
Timed mode — adjustable 100ms to 10 seconds
Next-note mode — holds until the next key is pressed
Infinite mode — note sustains indefinitely
Disabled mode — standard behavior when not needed

For: ALS, myasthenia, arthritis, fibromyalgia, severe fatigue

One-Finger Chord · Full Harmony — One Key

One-Finger Chord

One key = one full chord. Complete music with one hand.

Three modes — Auto (chord follows the scale), Split (bass + chord from one zone), Single (direct mapping). Four voicings let you choose the density of the harmony.

Auto mode — chord type follows the current scale
Split mode — bass + chord from a single keyboard zone
Single mode — direct one-to-one chord mapping
4 voicings — from sparse to full orchestral density

For: Hemiplegia, amputation, one-hand playing
